effector cell

1 a terminally differentiated leukocyte that performs more than one specific function.
2 a muscle cell or gland cell.

effector cell

A cell that carries out the final response or function of a particular process. The main effector cells of the immune system, for example, are activated lymphocytes and phagocytes—the cells involved in destroying pathogens and removing them from the body.

1. a muscle or gland that contracts or secretes, respectively, in direct response to nerve impulses.
2. a molecule that binds to an enzyme with an effect on its catalytic activity, i.e. either an activator or inhibitor.
