WebA T-helper cell binds to the APC and activated the B-cell. The B-cell then starts dividing himself in to effector and memory cells. The effector cell produces antibodies / immunoglobulins which tag antigens so they'll be detected and destroyed by the non-specific immune system: fagocytes. Am I right? WebT cells are divided into two broad categories: CD8+ T cells or CD4+ T cells, based on which protein is present on the cell's surface. T cells carry out multiple functions, including killing infected cells and activating or recruiting other immune cells. CD8+ T cells also are called cytotoxic T cells or cytotoxic lymphocytes (CTLs).
