antibodies are produced by..
B cells
Antibodies are proteins produced by a specific type of white blood cell called B lymphocytes (B cells) in response to the presence of a foreign substance (antigen) in the body. When a B cell recognizes an antigen, it undergoes a process of activation and differentiation, and ultimately changes into a plasma cell. Plasma cells are specialized B cells that produce and secrete large amounts of antibodies into the blood circulation.
Antibodies play a critical role in the immune system’s response to infections and diseases. They bind specifically to the antigen on the surface of pathogens such as bacteria, viruses, or parasites, making it easier for other immune cells to recognize and destroy them. In addition to their role in fighting infections, antibodies are also used in immunotherapy treatments to treat cancer, autoimmune diseases, and other conditions.
