Explanation / Answer

List the three main stages of T cell development. selection, differentiation and maturation.

List the three main surface molecules that are used to define the major stages of T cell development: CD4 , CD8 and Memory T cells.

List the two chains of the T cell receptor found on developing and mature CD4 and CD8 T cells CD4 glycoprotein and CD8 glycoprotein.
