Detailed explanation-1: -Helper T cells stimulate the B cell through the binding of CD40L on the T cell to CD40 on the B cell, through interaction of other TNF-TNF-receptor family ligand pairs, and by the directed release of cytokines.
Detailed explanation-2: -Once the initial steps of activation have occurred, helper T cells synthesize other proteins, such as signaling proteins and the cell-surface receptors to which the signaling proteins bind.
Detailed explanation-3: -Helper T-cells stimulate B-cells to make antibodies and help killer cells develop. Killer T-cells or cytotoxic T-cells directly kill cells that have already been infected by a foreign invader.
Detailed explanation-4: -Adaptive Immune Responses to Infection Activated T helper cells also secrete cytokines that lead to activation of other T helper cells as well as activating Tc and B lymphocytes. The result is a population of lymphocytes cytotoxic for infected cells and antibody production.
