Roles of B Cells, T Cells, and Progenitor Cells in the Immune System

B cells, T cells and progenitor cells

B cells, T cells, and progenitor cells are all types of cells involved in the immune system’s response to foreign substances and pathogens.

B cells are a type of white blood cell that produce antibodies, proteins that bind to specific antigens on pathogens and mark them for destruction by other immune cells. B cells also play a role in the development of immunity through memory B cells, which can quickly respond to subsequent exposure to the same pathogen.

T cells are another type of white blood cell that play a critical role in the immune response. They can recognize and respond to specific antigens on the surface of infected or abnormal cells, such as cancer cells or cells infected with viruses. T cells can directly attack these cells or release chemicals that attract other immune cells to help destroy them.

Progenitor cells are stem cells that are capable of differentiating into other types of cells, including B cells and T cells. These cells are responsible for the ongoing production and replenishment of the immune system’s cells.

In summary, B cells produce antibodies, T cells attack infected or abnormal cells, and progenitor cells differentiate into other immune cells. All three of these types of cells are crucial components of the immune system’s response to foreign substances and pathogens.
