Protein tyrosine kinase activity following T-cell stimulation:
A Phosphorylates and thereby activates phospholipase C gamma 1.
B Is an inherent property of the T-cell receptor alpha and beta chains.
C Is an inherent property of CD3.
D Is unaffected by herbimycin A.
E Is unrelated to phosphorylation of the CD3-associated zeta chains.
Give this one a try later!
A Phosphorylates and thereby activates phospholipase C gamma 1.
In the immunological synapse:
A The acetylcholine receptor in expressed on the T-cell.
B Production of substance P by the antigen-presenting cell is a key event.
C The initial interaction between TCR and MHC is unstable.
, D Adhesion molecule pairs eventually move to the center of the synapse.
E The B7-CD28 interaction is redundant.

C The initial interaction between TCR and MHC is unstable.
A naïve T cell refers to a T cell that:
a. does not express CD4+ or CD8+.
b. has not left the bone marrow.
c. has not yet encountered an antigen.
d. is not mature.
e. resides in the thymus.
