Explanation:
Detailed explanation-1: -CD4 cells are a type of white blood cell. They’re also called CD4 T lymphocytes or “helper T cells.” That’s because they help fight infection by triggering your immune system to destroy viruses, bacteria, and other germs that may make you sick.
Detailed explanation-2: -There are two main mechanisms of immunity within the adaptive immune system – humoral and cellular. Humoral immunity is also called antibody-mediated immunity. With assistance from helper T cells, B cells will differentiate into plasma B cells that can produce antibodies against a specific antigen.
