lymphocyte

Also known as lymphoid cell, lymphocytes, lymphocyte (Blood Cells)

A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an important subtype (which functions in cell-mediated, cytotoxic innate immunity). They are the main type of cell found in lymph, which prompted the name "lymphocyte" (with cyte meaning cell). Lymphocytes make up between 1

AI overview

A lymphocyte is a type of white blood cell that plays a central role in your immune system by helping fight infections and maintain health through various mechanisms—some cells produce antibodies, others directly attack infected cells, and some regulate immune responses in your body's tissues. They are called lymphocytes because they are the main type of cell found in lymph, a fluid that circulates through your immune system.
