1)Effector cytokines act exclusively on T cells

2)Th17 and TFH cell subsets are the major sources of B cell help

3)Signal three (3) in T Cell activation is provided by negative costimulatory receptors.

Answer 1

Correct sentences could be :

1) Cytokines act exclusively on cells having/bearing specific receptors on them.

2) Only TFH cell subsets ate the major source of B cell help while The17 is the subsets of the CD4+ T cells which involves in the inflammatory process in most of the immune response.

3) Full T-cell activation requires 2 signals which is provided by positive costimulatory receptors. ( negative costimulatory receptors seems necessary for the inducing t-cell tolerance).
