Put the following steps in order for cell-mediated immune
reactions:
(a) Differentiated T cells include T helper, delayed hyper-
sensitivity, cytotoxic, and memory T cells that all have
different immunological functions depending on the an-
tigen presented.
(b) Antigen-presenting cells (macrophages and dendritic
cells) phagocytize pathogens, ingesting and degrading
them into pieces which are transported to the surface of
the cell.
(c) T cells bearing the corresponding receptor for the pre-
sented antigen bind to it and become activated only if
the appropriate MHC is also present.
(d) Some pieces of the pathogen’s antigens are processed
by inserting them into the antigen-presenting cell’s
membrane and are held in place by class II major
histocompatibility complex (MHCII) proteins.
(e) Activated T cells are stimulated to divide and differen-
tiate into different types of T cells, including memory
cells
