In order to become activated, these cells use their TCRs and CD8 molecules to bind to dendritic cells with MHC-I molecules with attached epitope on their surface. These cells capture and present protein antigens to effector T4-lymphocytes. When the MHC-II molecules with bound peptide on these cells are recognized by complementary shaped T-cell receptors (TCR) and CD4 molecules on a T(h)1-lymphocyte, the cell becomes activated and able to destroy intracellular pathogens. These cells are derived from T-lymphocytes and develop anamnestic response for heightened future response to the initiating antigen. These cells develop from B-lymphocytes and secrete vast quantities of antibodies. These cells interact with MHC-II molecules with bound epitope on the surface of activated B-lymphocytes and secrete cytokines which stimulate the proliferation and differentiation of these B-lymphocytes. a. T4-effector cells b. plasma cells c. macrophages d. T-memory cells e. naïve T8-lymphocytes 75. activated and able to destroy intracellular pathogens. 76.
