APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Natural killer (NK) cells. These are large granular lymphocyte-like cells with important functions in innate immunity. Although lacking antigen-specific receptors, they can detect and attack certain virus-infected cells.

Detailed explanation-2: -Lymphocyte There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body’s own cells that have themselves been taken over by viruses or become cancerous.

Detailed explanation-3: -Lymphocytes are a type of white blood cell. They help your body’s immune system fight cancer and foreign viruses and bacteria.

Detailed explanation-4: -B lymphocytes, also called B cells, create a type of protein called an antibody. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection.
