Chapter 5 T Cell Receptors and Antigen Recognition: MHC, Diversity, and Immune Specificity Explained

Unlock the complexity of T cell antigen recognition in this detailed Chapter 5 lecture! Ideal for immunology students, medical professionals, and biology educators, this video covers the structure, generation, and function of T cell receptors (TCRs) and their interaction with MHC molecules. Key topics include: T Cell Receptor Structure: Similarity to immunoglobulin Fab fragments and membrane-bound nature TCR Diversity: V(D)J gene recombination and the essential role of RAG genes in adaptive immunity CD3 Complex and γδ T Cells: Surface expression and alternative TCR types Antigen Recognition: TCRs recognize processed peptides bound to MHC molecules MHC Classes I and II: Structural differences, antigen presentation, and cell-type expression Antigen Processing Pathways: ER loading (MHC I), endosomal presentation (MHC II), and cross-presentation Peptide Binding: Specificity, diversity, and the role of the peptide-loading complex and invariant chain HLA Genes and Polymorphism: Genetic diversity and its impact on immunity and disease resistance Understand how T cells distinguish pathogens through precise molecular interactions, shaping the adaptive immune response.
