Computational neutralization fingerprinting, NFP, is an efficient and accurate method for predicting the epitope specificities of polyclonal antibody responses to HIV-1 infection. Here, we present next-generation NFP algorithms that substantially improve prediction accuracy for individual donors and enable serologic analysis for entire cohorts. Specifically, we developed algorithms for: (a) sel...
Background and purpose: In 2019, the world has witnessed the emergence of a virus that caused acute respiratory distress syndrome in human with high mortality rates (approximately 3.7%). So far, no effective treatment has been proven against COVID-19. This study aimed at designing a multi-epitope vaccine combining several T-cell and B-cell epitopes of the SARS-CoV-2. Materials and methods: Bas...
Identification of antigen-antibody interacting sites is an important task for vaccine design, and hence reliable computer based prediction methods are highly desirable. The prediction performances of the current existing methods to predict the conformational B-cell ep itope residues are still not satisfying and remain far from ideal. This is a new approach in the area of vaccine development to ...
Contagious human coronavirus belong to family Coronaviridae and infects respiratory system causing the disease known as COVID-19 (WHO). To eradicate severe acute syndrome 2 pandemic, an effective vaccine should be developed. In current study immunoinformatics procedures were employed introduce a novel multi-epitope subunit vaccine. This can activate equally class I II leukocyte antigen antibody...
T-cell CD4+ epitopes are important targets of immunity against infectious diseases and cancer. State-of-the-art methods for MHC class II epitope prediction rely on supervised learning methods in which an implicit or explicit model of sequence specificity is constructed using a training set of peptides with experimentally tested MHC class II binding affinity. In this paper we present a novel met...
CD4+ T cells play critical roles in initiating, regulating, and maintaining antitumor immune responses. One way to improve current tumor vaccines that mainly induce CTLs would be to activate antigen-specific CD4+ T cells that recognize MHC class II restricted tumor associated antigens. Human telomerase reverse transcriptase (hTRT) is preferentially expressed by various tumors and, therefore, co...
Identification and validation of T-cell epitopes in outer membrane protein (OMP) of Salmonella typhi
This study aims to design epitope-based peptides for the utility of vaccine development by targeting outer membrane protein F (Omp F), because two available licensed vaccines, live oral Ty21a and injectable polysaccharide, are 50% to 80% protective with a higher rate of side effects. Conventional vaccines take longer time for development and have less differentiation power between vaccinated an...
BACKGROUND HLA class-I alleles differ in their ability to control HIV replication through cell-mediated immune responses. No consistent associations have been found between the breadth of Cytotoxic T Lymphocytes (CTL) responses and the control of HIV-1, and it is unknown whether the size or distribution of the viral proteome-wide epitope repertoire, i.e., the intrinsic ability to present fewer,...
As epitope mimics, mimotopes have been widely utilized in the study of epitope prediction and the development of new diagnostics, therapeutics, and vaccines. Screening the random peptide libraries constructed with phage display or any other surface display technologies provides an efficient and convenient approach to acquire mimotopes. However, target-unrelated peptides creep into mimotopes fro...
T cell immune responses are driven by the recognition of peptide antigens (T cell epitopes) that are bound to major histocompatibility complex (MHC) molecules. T cell epitope immunogenicity is thus contingent on several events, including appropriate and effective processing of the peptide from its protein source, stable peptide binding to the MHC molecule, and recognition of the MHC-bound pepti...
