ANATOMY

Detailed explanation-1: -Both TH1 and TH2 cells can help stimulate B cells to proliferate and differentiate into either antibody-secreting effector cells or memory cells.

Detailed explanation-2: -There are two main types of T-cells: 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-3: -Helper T-cells are one of the most important parts of your adaptive immunity. They’re involved in almost all adaptive immune responses. They activate two types of cells: B-cells, which produce antibodies, the chemicals designed to fight specific foreign substances.

Detailed explanation-4: -T cells can wipe out infected or cancerous cells. They also direct the immune response by helping B lymphocytes to eliminate invading pathogens. B cells create antibodies. B lymphocytes, also called B cells, create a type of protein called an antibody.
