Cells of the Immune System

Platelets are not white blood cells, they are involved in blood clotting.

Neutrophils are phagocytic cells that engulf and destroy bacteria.

B cells are responsible for producing antibodies, which are proteins that recognize and bind to specific antigens.

Natural killer cells are cytotoxic lymphocytes that kill virus-infected cells and tumor cells.

Dendritic cells are antigen-presenting cells that capture and process antigens and present them to T cells.

Macrophages are phagocytic cells that engulf and destroy bacteria, viruses, and other foreign particles.

Regulatory T cells are a type of T cell that helps to control the immune response and prevent autoimmune diseases.

Eosinophils are phagocytic cells that are involved in fighting parasitic infections.

Both T cells and B cells can produce memory cells, which are long-lived cells that can quickly respond to a previously encountered antigen.

Basophils are involved in allergic reactions by releasing histamine and other inflammatory mediators.

Natural killer cells produce interferon, which is a cytokine that helps to fight viral infections.

Mast cells are involved in allergic reactions and inflammation by releasing histamine and other inflammatory mediators.

T cells produce interleukin-2, which is a cytokine that helps to activate other immune cells.

Plasma cells are differentiated B cells that produce antibodies.

Macrophages produce tumor necrosis factor, which is a cytokine that helps to kill tumor cells.
