We show that IRF4 is differentially required for long-term survival of CD8+ mem-ory T cell subsets. In particular, maintenance of tissue-resident memory T cells appears to depend on IRF4. Upon reactivation, IRF4-deficient CD8+ memory T cells are strongly impaired in theirproliferation andcytokine ...

Immunity 47, … WebDec 6, 2024 · In agreement with the lack of a role for STAT3 in TNF-Th17 cell generation, TNF-induced IRF4 up-regulation was similar in STAT3-deficient and WT CD4 + T cells (SI Appendix, Fig. S6D). The dependence of TNF-Th17 generation on IRF4 was shown by the reduction of ROR-γt expression ( Fig. 2 J ) and IL-17A production ( Fig. 2 K ) in its absence.
IRF4 is a transcription factor belonging to the Interferon Regulatory Factor (IRF) family of transcription factors. In contrast to some other IRF family members, IRF4 expression is not initiated by interferons; rather, IRF4 expression is promoted by a variety of bioactive stimuli, including antigen receptor engagement, lipopolysaccharide (LPS), IL-4, and CD40. IRF4 can function either as an activating or an inhibitory transcription factor depending on its transcription WebWe found that IRF4 was promptly induced in T cells upon TCR signaling through the MEK1/2 pathway. IRF4 ablation in T cells resulted in progressive establishment of CD4 + T cell …
