Question 1

Which of the following BEST describes how cytokines are released from activated T cells?

Accepted Answer

A) Cytokines are released near where T-cell receptors are clustered. 
B) T cells release cytokines on the side of the cell opposite the MTOC to more efficiently distribute the response around the cell. 
C) T cells release cytokines evenly around the cell. 
D) Cytokines are released in short bursts from preformed vesicles full of cytokines. 
E) Cytokines are released in whatever direction the MTOC happens to be facing upon TCR ligation.
