IMMUNOLOGY

Detailed explanation-1: -Synthesized exclusively by B cells, antibodies are produced in billions of forms, each with a different amino acid sequence and a different antigen-binding site.

Detailed explanation-2: -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.

Detailed explanation-3: -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-4: -In fetuses, the liver makes B-cells. Once you’re born, B-cells develop in the spongy tissue inside your bone called bone marrow. They start as hematopoietic stem cells and eventually become B-cells during a process called hematopoiesis.

Detailed explanation-5: -Plasma cells are differentiated B-lymphocyte white blood cells capable of secreting immunoglobulin, or antibody. These cells play a significant role in the adaptive immune response, namely, being the main cells responsible for humoral immunity.

Detailed explanation-6: -The B Cells have the ability to transform into plasmocytes and are responsible for producing antibodies (Abs). Thus, humoral immunity depends on the B Cells while cell immunity depends on the T Cells.

Detailed explanation-7: -Types of T-cells Helper T-cells stimulate B-cells to make antibodies and help killer cells develop.
