MICROANATOMY

Detailed explanation-1: -T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.

Detailed explanation-2: -Cytokines are a collective name of lymphokines (cytokines secreted by lymphocytes), monokines (cytokines secreted by monocytes), interleukins (cytokines secreted by one leukocyte and acting on other leukocytes), chemokines (cytokines with chemotactic activities), etc.

Detailed explanation-3: -Lymphokines are a subset of cytokines that are produced by a type of immune cell known as a lymphocyte. They are protein mediators typically produced by T cells to direct the immune system response by signaling between its cells.

Detailed explanation-4: -: any of various substances (as an interleukin) of low molecular weight that are not antibodies, are secreted by T cells in response to stimulation by antigens, and have a role (as the activation of macrophages or the enhancement or inhibition of antibody production) in cell-mediated immunity.
