What are lymphocytes-?

Lymphocytes are a type of white blood cell that play a critical role in the body's immune system. They are produced in the bone marrow and then mature in the thymus gland before circulating throughout the body. There are two main types of lymphocytes: B cells and T cells. B cells produce antibodies, which are proteins that recognize and bind to specific antigens. When an antigen binds to an antibody, it triggers the B cell to divide and produce more antibodies, which can then neutralize the antigen and prevent it from causing infection. T cells directly attack infected cells or cancer cells. They do this by recognizing and binding to specific antigens on the surface of the infected or cancerous cell. Once bound, the T cell releases toxins that kill the cell. There are three main types of T cells: helper T cells, cytotoxic T cells, and regulatory T cells. Helper T cells help B cells to produce antibodies, while cytotoxic T cells directly kill infected or cancerous cells. Regulatory T cells help to control the immune response and prevent it from attacking healthy tissue. Lymphocytes are essential for the body's ability to fight infection and cancer. They work together to provide a robust and adaptable immune response that can protect the body from a wide range of threats.
