WebSep 9, 2024 · Cytotoxic CD4 T lymphocytes (CD4-CTL) are important in antiviral immunity. For example, we have previously shown that in mice, CD4-CTL are important to control ectromelia virus (ECTV) infection. How viral infections induce CD4-CTL responses remains incompletely understood. We demonstrate here that not only ECTV but also vaccinia … WebWhen a cytotoxic T cell (CTL) recognizes a peptide presented in the MHC-1 of a dendritic cell (APC), why it doesn't kill this cell? I know that initially, in the lymph node, the T cell is inactivated. But eventually it becomes activated and travels to the tissue, where it again finds APCs presenting the offending antigen.
