WebFeb 1, 2024 · Spike-specific T cell responses are CD4 + dominated and are likely to support antibody generation, with follicular helper T cells correlating with humoral immunity in the memory phase 53,54,55. Cell-mediated immunity or cellular immunity is an immune response that does not involve antibodies. Rather, cell-mediated immunity is the activation of phagocytes, antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.
