Detailed explanation-1: -The adaptive immune response in B cells, Helper T cells and Cytotoxic T cells involved four phases: encounter, activation, attack, and memory. in this response, activated T cells differentiate and proliferate, becoming Helper (TH) cells or Cytotoxic (TC) cells.
Detailed explanation-2: -There are three stages during T cells activation by DCs, namely antigen presenting, antigen recognition of T cells and two signals formation. In addition, IS formation between T cells and DCs plays an important role in T cell activation.
Detailed explanation-3: -There are 3 stages in the process of cell-mediated immunity. These are: Cognitive-It shows foreign antigens in a particular form recognized by helper T (Th1) lymphocytes. Activation-Th1 cells produce cytokines to help in the proliferation & differentiation of all T cells and macrophages.
Detailed explanation-4: -Antigen enters tissues, lymphocytes sensitised, antigen passed to members of a clone of lymphocytes, macrophages engulr antigen, T-lymphocytes attack antigen-bearing agents.
Detailed explanation-5: -The normal immune response can be broken down into four main components: pathogen recognition by cells of the innate immune system, with cytokine release, complement activation and phagocytosis of antigens.
