Department of Biotechnology started the Bioinformatics in 1987 as one of the thrust areas of Biotechnology and the sustained support has given impetus to the development of Bioinformatics in the country through establishing the necessary infrastructure including the ‘Supercomputer’. This can be addressed by utilizing several computer programs to analyze each of these properties and by bioinformatics tools for the screening and selection of vaccine candidates, according to their top feature values. Freely available bioinformatics tools and an unprecedented volume of –omics data now present an opportunity for in silico vaccine discovery for eukaryotic pathogens. This tool can be used to select the appropriate size of a peptide in order to render its stability and to introduce stabilizing mutations or chemical modifications that minimize flexibility, hence yielding better vaccine candidates than simple peptides. This method can be applied to previously predicted peptides and is expected to improve prediction accuracy in order to identify the best MHC class I and II binders. MenB is a major cause of sepsis and meningitis in North and South America, Canada, Europe, Australasia, and many other countries, but developing an effective vaccine was for many years an unsolved problem. Molecular docking tools can be used to establish interaction between two or more molecules (antibodies and cell receptors). In the search for a vaccine to fight drug abuse, cocaine, nicotine, and methamphetamines are some of the main targets; however, to date there are, to our knowledge, no US: Federal Drug Administration (FDA)‐approved vaccines. 9.12, CHARMM, WhatIF, PROCHECK, Verify 3D), and structure‐based epitope prediction for E protein, NS3, and NS5. The main drawbacks in this are that many predicted epitopes are buried within the protein; thus, they would not be detected by the antibodies. Then they introduced these mutations individually into CHIKV and identified a panel of E2 mutations that confer reduced virulence in a murine model. Realization will depend on the application of flanking logistic and regulatory measures and the awareness of the strong impact of vaccine development to solve global health problems. They predicted MHC‐I restricted epitopes, and then performed docking of these peptides with human leukocyte antigen (HLA) receptors to confirm their predictions. Citations of this article. predicted, using the same strategy, B‐ and T‐cell peptides belonging to Per a 9 and Per a 10 (two major allergens as assessed by enzyme‐linked immunosorbent assays (ELISA) but, in order to obtain substantial quantities of these allergens for use in functional studies, they cloned and expressed them in an Escherichia coli system [78, 79]. It is important to study the similarity between the sequences under study with molecules from the host that will receive the vaccine, as well as between the related etiological agents. Funding is also required for the basic research needed to provide the basis for rationally developed vaccines. Toxicity analyses included allergenicity prediction. Some of the important properties to detect good vaccine candidates are described as follows: Proteins are localized in different parts of the cell: in the cytoplasm, the cell membrane, or they can be secreted out of the cell and become extracellular. Dikhit et al. The development of such products has been hindered by the need of a carrier protein and an adjuvant to combine with haptens of the drugs to elicit the necessary antibody levels expected to interfere with the transport of the drug to the Central Nervous System (CNS), thus with the expected effect [72]. In 2016, Yang et al. or subcutaneously (s.c.) showed no serious adverse events (SAEs) during the study and no subject withdrew from the latter due to an adverse event. However, despite their practical and societal value, vaccines remain only a small component of the global pharmaceutical market ($5 billion out of $350 billion sales in 2000). Table 1. This chapter provides an overview of the application of bioinformatics strategies in vaccine design and development, supplying some successful examples of vaccines in which bioinformatics has furnished a cutting edge in their development. None has a more persuasive potential impact than the application of computational informatics to vaccine discovery; the recent expansion in genome data and the parallel increase in cheap computing power have placed the bioinformatics exploration of pathogen genomes centre stage for vaccine researchers. Keywords: Viral diversity, Bioinformatics, Vaccine design, Target discovery, Reverse vaccinology, Database, Tools Background Novel vaccine design strategies are required to overcome the deficiency in the immune response to pathogens that do not naturally result in lasting immunity [ 1 ], such as human immunodeficiency virus (HIV), influenza, dengue, and hepatitis C, among others. The complexity of some experimental tools such as mass spectrometry hampers its usefulness in the selection of targets in a clinical setting where personalized therapy is needed. In 2011, Worm et al. To achieve an analysis, the “immunome” of an organism is required; this includes all of the genes and proteins of cells that take part in its immune response. reported such data, to our knowledge for the first time, using new computational methods for annotation of mature peptide proteins, genotypes, and recombination events for all ZIKV genomes [70]. In the case of CHIKV, an LAV candidate, attenuated by serial passages in MRC‐5 fibroblasts, the authors predicted an amino acid substitution at E2 position 82, which was highly dependent upon ionic interaction with HS for infectivity. Search term. The immunological system can be classified as cellular or humoral and, depending on the disease, it can be induced the expected immune response. Currently, there are many bioinformatics programs that predict protein epitopes. In such a situation, work progresses cyclically using and refining models and experiments, moving toward the goal of effective and efficient vaccine development. Impact of bioinformatics in vaccine discovery: Due to increase in the concentration of pathogens in the environment, the demands for vaccines to eradicate them at the initial stage are very high. The next stage will come with closer connections between immunoinfor-maticians and experimentalists searching for new vaccines, both academic and commercial, conducted under a collaborative or consultant regime. and Tong et al. Antitoxins and vaccines against diphtheria, tetanus, anthrax, cholera, plague, typhoid, tuberculosis, and more were developed through the 1930s. However, misinformation and the consequent mistrust of vaccinations pose a threat to their success and positive impact on global human health. TT is used as a carrier; FliC acts as a carrier protein, and additionally it has been demonstrated that it stimulates toll‐like receptor 5 (TLR5), therefore inducing myeloid differentiation factor 88 (MyD88), which renders a TH2 response to predominant production of IgG1 and no cytotoxic T lymphocytes (CTL). The vaccine market is dominated by just four large manufacturers: GlaxoSmithKline, Aventis Pasteur, Wyeth, and Merck & Co. [67] utilized ProPred1 to predict antigenic epitopes for HLA class I, as well as 48 antigenic epitopes for HLA class II employing ProPred immunoinformatics algorithms. Additionally, antibodies against regulatory T‐cells have been found with aid in the regression process of the tumor [9, 31]. [34] developed universal vaccine candidates against serotype 1 Streptococcus pneumoniae considering epitope prediction and structure modeling. Reverse vaccinology is a methodology that uses bioinformatics tools for the identification of structures from bacteria, virus, parasites, cancer cells, or allergens that could induce an immune response capable of protecting against a specific disease [7]. By making research easy to access, and puts the academic needs of the researchers before the business interests of publishers. It’s based on principles of collaboration, unobstructed discovery, and, most importantly, scientific progression. One premise of bioinformatics is to detect epitopes that can be recognized by antibodies, but modeling antibody‐antigen complexes has been difficult because of the mobility of protein loops in the Fab region of antibodies [40]. And then, at the dawn of bacteriology, developments rapidly followed. In the case of cancer vaccines, antigens present in B cell have been developed that can help in the cancer cell elimination process. It has been asserted that vaccination, as well as clean water, has had such a major effect on mortality reduction and population growth [1, 2]. Afterward, this mutation demonstrated the attenuation two strains of CHIKV in vivo. Protein or nucleic acid sequences can be aligned to detect conservation and strain or species coverage. This is a concern, especially with peptides, which are usually more flexible and disordered than when they are found in a complete protein context. Several bioinformatics studies perform toxicity or allergenicity prediction on peptide candidates to rule out adverse effects in the resulting candidate vaccine [38, 39]. Vaccines are the pharmaceutical products that offer the best cost‐benefit ratio in the prevention or treatment of diseases. Another study proposed a multivalent vaccine with fused peptides against Staphylococcus aureus. For this purpose, several software systems and programs identify all open reading frames (ORFs) that constitute the sequences expressing the majority of proteins [8–10].

For a vaccine against this pathogen, multiple bioinformatics strategies are being exploited as an essential tool; the majority of studies involve in silico predictions to find the best epitopes. A vaccine is a molecular or supramolecular agent that induces specific, protective immunity (an enhanced adaptive immune response to subsequent infection) against micro-bial pathogens, and the diseases they cause, by potentiating immune memory and thus mitigating the effects of reinfection. It is now widely accepted that mass vaccination, which takes into account herd immunity, is the most efficacious prophylactic treatment for contagious disease. INTRODUCTION. This has aided in expanding the concept and application of vaccines beyond their traditional immunoprophylactic function of preventing infectious diseases, and also serving as therapeutic products capable of modifying the evolution of a disease and even cure it [3]. By Waldely de Oliveira Dias, Ana Fabíola R.O. Molecules with adhesin properties are vaccine candidates [16]. Structural information is utilized to map antigenic epitopes to detect conformational features that could affect immunogenicity, such as the structural stability of proteins or the solvent exposure of candidate peptides, and to select antigenic regions shared by proteins of different pathogens that otherwise (i.e., by multiple alignments or epitope mapping) could not be evident. Several candidates are undergoing preclinical and clinical studies, and some platforms being investigated include inactivated, subunit/peptide, DNA‐based, live‐attenuated, and vectored vaccines. E-mail address: [email protected]. These characteristics must be analyzed for each protein in the proteome under study, employing different bioinformatics approaches to select the protein(s) with the best properties for testing through in vitro and in vivo assays, in order to demonstrate its safety and immunogenicity. Available from: Special cases: vaccines against infectious and noninfectious diseases, Laboratory of Production and Biological Control, Department of Microbiology, National School of Biological Sciences, National Polytechnic Institute, Mexico City, Mexico, Laboratory of Medical Bacteriology, Department of Microbiology, National School of Biological Sciences, National Polytechnic Institute, Mexico City, Mexico. It also includes immunotranscriptomics, the application of microarray analysis to the immune system. Care should be taken while designing peptide‐based vaccines because the resulting peptide could be toxic or allergenic. All authors are grateful to COFAA‐IPN. Based on this fact [59], E2 mutations were selected that confer HS dependence on infectivity by serial passage of wild‐type CHIKV‐LR on different cell types in vitro. As part of the study, these authors included computational modeling utilizing the structural data of the E2 retrieved from PDB and visualizing the results using UCSF CHIMERA software. In this context, because it is not possible to analyze all of the mutations, bioinformatics addresses this problem and has become important in the selection of targets and in their prioritization [80]. On the other hand, if a humoral response is required, the software needs to identify antigens for B cells, for example, in the case of influenza virus or HIV [24, 25]. There are Websites and downloadable software that can be useful for a particular reverse vaccinology analysis, for example, NERVE, Vaxign, Jenner‐predict server, and Vacceed. They concluded that their developed epitope-based vaccine could efficiently result in both preventive and therapeutic antitumor immunity in … Finally, the stability of these interactions can be assessed through energy calculations or molecular dynamics simulations. Other software developers have addressed the analysis of the complete immune response against specific antigens, such as C‐ImmSim. The number of new cases worldwide rose to 10.4 million [42]; this high incidence rate is based on several factors, and one of the most important factors is the ineffectiveness of the vaccine used at present: the BCG. In allergies, computational approaches have been applied to find T‐cell epitopes to target allergen‐specific T cells, thus improving the safety of the immunotherapy. Again, bioinformatics was necessary to assess the secondary structure and MHC‐II binding predictions for FliC and mFliC, employing the PSIPRED (http://bioinf.cs.ucl.ac.uk/psipred/) method and the external software from IEDB (http://www.immunoepitope.org/), respectively [74]. Some common allergies are caused by cat, peanut, and cockroach allergens, with the specific immunotherapy (SIT) effective, but sometimes associated with IgE‐dependent adverse events. Eukaryotic pathogens are extremely complicated systems with … In this work, computational modeling played an important role because it helped to explain the effect of the single amino acid mutations on altering the electrostatic profile of the E2 glycoprotein and increasing net positive charge in two exposed regions. Bioinformatics has now become a common laboratory name for groups studying genomic sequences. Most of the time, vaccine candidates are expressed in biological systems that are different from the original source; in that case, the three‐dimensional (3D) structure of the protein could be changed or difficult to purify if it has a transmembrane helix, due to differences in membrane structure [21]. The vaccine administered intradermally (i.d.) Chen et al. There have been two main types of informatics support for vaccines. For CHIKungunya Virus (CHIKV), there are some vaccine candidates in clinical trials, but there is no licensed vaccine to date. It has been found that neutralizing antibodies can bind to intact trimers, confirming the possibility of a universal vaccine aimed at the HA stem. It is composed of many different, yet interrelated scientific fields such as genomics, proteomics, and transcriptional profiling. Reverse vaccinology, immunoinformatics, and structural vaccinology are described and addressed in the design and development of specific vaccines against infectious diseases caused by bacteria, viruses, and parasites. Bioinformatics analyses have been performed to improve the functionality of antibodies. Vaccinology and immunology are now at a turning point. Allergies comprise another area where vaccine (specific immunotherapy (SIT)) investigation is conferred due to the association of allergy with asthma and anaphylaxis. The initial stage in bioinformatics analyses involves linear epitope prediction, taking hydrophilicity as the major characteristic for locating epitopes. T cells express a particular receptor: the T cell receptor (TCR), which exhibits a wide range of selectivities and affinities. This approach possesses many advantages over traditional vaccinology: it reduces time and cost in vaccine development; refines the number of proteins to be studied, facilitating the selection process; can identify antigens present in small amounts or expressed only at certain stages, which would hinder or prevent their purification; and allows for the study of noncultivable or risky microorganisms [3]. TCRs bind to major histocompatibility complexes (MHCs) presented on the surfaces of other cells. It consists of complexing two molecules (protein‐protein or protein‐ligand) with best shape complementarity and minimal binding energy. If a vaccine that induces a cellular response is needed, for example a tuberculosis vaccine [22] or a parasite vaccine against leishmaniasis [23], the software must search for antigens that can be recognized by the major histocompatibility complex (MHC) molecules present in T lymphocytes [4]. They performed molecular docking of the ZIKV‐E protein with HLA‐A0201, of the ZIKV‐NS3 protein with HLA‐B2705, and of the ZIKV‐NS5 protein with HLA‐C0801 (PatchDock rigid‐body docking server, FireDock server). From COVID-19 vaccines to drugs and data analysis: How AWS is helping in the global pandemic response. Regarding allergy to cockroaches, there are some research studies that have followed the in silico prediction of B‐cell, T‐cell, and IgE‐binding epitopes in a first stage to propose a vaccine formulation. The first is standard bioinformatics support, technically indistinguishable from support for more general target discovery. Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. In addition to the invaluable role of traditional vaccines to prevent diseases, the society has observed remarkable scientific and technological progress since the last century in the improvement of these vaccines and the generation of new ones. Several approaches have been applied to reduce the times and costs of their development, mainly focusing on the selection of appropriate antigens or antigenic structures, carriers, and adjuvants [6]. Moreover, it requires not only an understanding of immunology but also the integration of many disciplines, both experimental and theoretical. There are known sequences of antigens with good in vivo and in vitro immunologic inductions that are compared with each sequence of the proteome under study in order to search for similarities. Traditionally, vaccines have been attenuated or "weakened" whole pathogen vaccines such as BCG. employed three immunoinformatics tools: the Protean™ system (DNAStar, Inc., Madison, WI, USA); the bioinformatics predicted antigenic peptides (BPAP) system (http://imed.med.ucm.es/Tools/antigenic.pl), and the BepiPred 1.0 server (http://www.cbs.dtu.dk/services/BepiPred/), which utilizes four properties, including hydrophilicity, flexibility, accessibility, and antigenicity as parameters for the prediction of B‐cell epitopes. Many epitope‐based vaccines attempt to elicit an antibody‐mediated immune response that could neutralize the activity of toxins or pathogen receptors. Websites already exist that present databases with antigens, with their epitopes identified in several organisms, and other immunological information, for example, IEDB, SIFPEITHI, IMGT, MHCBN, AntiJen, Dana‐Farber Repository, and AgAbDb. However, considering these predictions as the sole factor in determining the potential of a sequence to be immunogenic is risky. The development of bioinformatics tools along with advances in recombinant DNA technology (rDNA) and the knowledge on the host immune response and the genetic background of the pathogen will lead to new vaccines against diseases that currently have few or no control measures in just 1 or 2 years through computer in silico predictions to define targets see Fig. The latter use different algorithms and some of these analyze the genome of the organism‐under‐study in order to identify new, probable MHC molecules. The Impact of Bioinformatics on Vaccine Design and Development, Vaccines, Farhat Afrin, Hassan Hemeg and Hani Ozbak, IntechOpen, DOI: 10.5772/intechopen.69273. Several conserved regions have been described in the stem region of HA [57], which make a universal vaccine a possibility. María R; Arturo C; Alicia J; et al. However, it is important to mention that in some instances, the vaccine candidate obtained by this technology could fail as a good vaccine antigen, because it is identified based solely on computational probabilistic studies, and there are other factors that could interfere when this antigen is administered in a complete organism. All of these vaccines have been proven effective, safe and had a great impact on public health. Login / Register. The next step in reverse vaccinology is to determine several antigenic and physicochemical properties that have been associated with good antigens. Licensee IntechOpen. They subsequently evaluated the antitumor efficacy of the vaccine through in vivo preventative and therapeutic assays. The Impact of Bioinformatics on Vaccine Design and Development. Contextualizing the Impact of Bioinformatics on Preclinical Drug and Vaccine Discovery. We share our knowledge and peer-reveiwed research papers with libraries, scientific and engineering societies, and also work with corporate R&D departments and government entities. Structural vaccinology focuses on the conformational features of macromolecules, mainly proteins that make them good candidate antigens. Hitherto, bioinformatics support for preclinical drug discovery has focused on target discovery. Several predictions can be mapped into the structure, such as epitope prediction or amino acid conservation. In the field of structural vaccinology, molecular docking can be employed to predict the binding of epitopes to antibodies or to MHC receptors. Some of these have been expressed and proven in vitro and in vivo, demonstrating their immunogenicity and protective effect. The other type of support is focussed on immunoinformatics and addresses problems such as the accurate prediction of immunogenicity, manifest as the identification of epitopes or the prediction of whole protein antigenicity. Hitherto, bioinformatics support for preclinical drug discovery has focused on target discovery. The immune system is complex and hierarchical, exhibiting emergent behavior at all levels, yet at its heart are straightforward molecular recognition events that are indistinguishable from other types of biomacromolecular interaction. The binding of an epitope to a MHC protein, or a TCR to a peptide-MHC complex, or an antigen to an antibody, is, at the level of underlying physicochemical phenomena, identical in nature to drug-receptor interactions. Alam et al. We are IntechOpen, the world's leading publisher of Open Access books. Dar et al. This has been possible by the fusion of computational technologies with the application of recombinant DNA technology, the fast growth of biological and genomic information in database banks, and the possibility of accelerated and massive sequencing of complete genomes [3–5]. Again, epitope prediction was followed by peptide structure prediction, docking with TLR2, molecular dynamics simulations to assess the stability of the complexes, and finally, allergenicity prediction [39]. Several candidates and epitopes have been found with different software. In addition, the vaccine candidates studied presented the characteristics described previously, such as nonhuman homology, adhesins [44], secreted or membrane structures [45, 46] with low transmembrane helix, and in addition, the proteins expressed in the latent or active state of the microorganism [47]. Darren R. Flower. Darren R. Flower . The study of all of the reactions that take part in the immune response is known as “immunomics” and it is specific for each organism; therefore, it is important to perform the study with information of the recipient organism. With the best vaccine candidates, different types of vaccines can be designed and developed, for example: subunit, recombinant, and nucleic acid vaccines [11]. In the opposite case, the hydrophobic amino acids are located in the center of the structure. Methods that accurately predict individual epitopes or immunogenic proteins, or eliminate microbial virulence factors, will prove to be crucial tools for tomorrow's vaccinologist. The stem region contains the fusion peptide and, although it previously was not considered a target for vaccine development, the discovery of neutralizing antibodies aimed at this region revealed its potential in vaccine design [52, 56]. Contact our London head office or media team here. for the treatment of peanut allergy, which presents symptoms ranging from mild oropharyngeal pruritus to life‐threatening anaphylaxis, considerably compromising the patient’s quality of life. Later, Pasteur adopted "vaccination"—the word coined by Jenner for his treatment (from the Latin vacca: cow)—for immunization against any disease. [69], in which the authors predicted antigenic B‐cell (IEDB) and CTL epitopes (NetCTL.1.2 server). [38], in a preliminary report, designed peptides as vaccine candidates against the Zika virus. In this case, the software uses different algorithms for each step; at the end, a series of graphic representations of each cell type can supply an idea of whether the response is sufficient to protect against a disease [32]. After virtual screening, they confirmed a predicted peptide agreement between their docked results and previous experimental results (i.e., the immunogenicity of this peptide was confirmed in vivo studies), thus proposing molecular docking as an additional technique to improve the selection of peptide candidates for cancer vaccines [83]. The aim of such a multi-disciplinary collection is to provide further insights and enhance the development of … Finally, these authors investigated the stability of the docked peptide‐MHC I protein complexes by performing Molecular Dynamics (MD) simulations (AMBER 12 simulation package) [69]. Molecules localized on the cell membrane or extracellularly are better antigens because they are more exposed to host cells, specifically to those related to the immune system; thus, they have a greater probability of generating a protective response [15]. Chen et al., Yang et al., and Tong et al. Mendeley users who have this article in their library. Influenza viruses evade the immune response through antigenic drift and antigenic shift [52], rendering a long‐lasting immune response very difficult. One of these approaches is the incorporation of bioinformatics methods and analyses into vaccine development. On the other hand, as they observed in prior experiments in which they conjugated GNE (a cocaine hapten) with FliC, TLR5 activation was attenuated at higher hapten densities (i.e., above ∼10 GNE per flagellin). The T cell, a specialized type of immune cell mediating cellular immunity, constantly patrols the body seeking out foreign proteins originating from pathogens. One of these approaches is the incorporation of bioinformatics methods and analyses into vaccine development. The goal of this Research Topic is to bring together the latest developments and opinions from different disciplines of precision vaccine development, such as systems vaccinology, omics development, human in vitro modeling, adjuvant discovery and development, and bioinformatics. One study modified the Fc portion of antibodies to increase binding of proteins to the antibodies’ Fc.
