A)NFAT and T-bet
B)AP-1 and GATA-3
C)Fos and STAT-6
D)NF-kB and IRFs
E)Lck and Jun

Question

Quizplus · Accepted Answer

The predominant signaling pathway used by Toll-like receptors (TLRs)results in the activation of the NF-F1F1F1S1F1F1F10B and immune regulatory factors (IRFs),which regulate promote expression of inflammatory genes and type 1interferon genes,respectively.T-bet and GATA-3 are transcriptional regulators involved in helper T cell differentiation.Fos is a component of AP-1,and STAT-6 is a transcription factor activated by IL-4 binding to cells.Lck is not a transcription factor,but rather a tyrosine protein kinase involved in antigen-receptor signaling in T cells.
