Adaptive immune receptors recognizing DTP-HepB-Hib antigens (TCR/BCR (DTP-HepB-Hib))

Adaptive immune receptors recognizing DTP-HepB-Hib antigens refer to the specific T-cell receptors (TCRs) and B-cell receptors (BCRs) that mediate the immune response to the components of pentavalent vaccines (WHO, 2017). These receptors recognize antigens from Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, Hepatitis B virus, and Haemophilus influenzae type b (CDC, 2021). The primary biological function of these receptors is the recognition of vaccine-derived epitopes, which triggers the activation of the adaptive immune system, including the production of high-affinity antibodies and the establishment of immunological memory (Janeway et al., 2001). By targeting these receptors, vaccines provide prophylactic protection against severe bacterial and viral infections. The interaction is highly specific, involving the binding of BCRs to surface epitopes and TCRs to processed peptides presented by major histocompatibility complex (MHC) molecules (StatPearls, 2023). Monitoring the efficacy of this interaction is typically performed by measuring serum antibody titers against the specific toxoids and surface antigens (PubMed, 2019).

The vaccine antigens interact with B-cell receptors (BCRs) and are processed for presentation to T-cell receptors (TCRs) via MHC molecules, leading to lymphocyte activation, clonal expansion, and the generation of long-lived memory cells and protective antibodies (Janeway et al., 2001; WHO, 2017).
