Chapter 17, Problem 10R
Summary Introduction
To review:
The phagocyte found in skin and lymphoid tissue that activate T cells.
Introduction:
The antigen presenting cells, which displays the antigenic substance, coupled with major histocompatibility molecules on their surfaces for the recognition of T cell receptors. There are some antigen presenting cells, such as dendrites, macrophages, and B cells. They presents the antigen for T helper cells to undergo the phagocytosis and cytotoxic effects.
