WebApr 12, 2024 · KLF2, a member of the Kruppel-like factor family, has diverse roles in the immune system, and in particular plays a critical role in controlling migration of T (and B) cells via its control of expression of key homing receptors which determine selective trafficking capabilities. Other functions of KLF2 remain mostly undefined. WebTo date, both KLF2 and KLF13 have been shown to be involved in the regulation of development of T cells. Expression of KLF2 is downregulated following treatment of T cells with anti-CD36 but may also be upregulated during the early stages of T cell activation.7 KLF2 has been shown to maintain T cells in a quiescent state8 to heater controller circuit

WebPeripheral CD8 + T cells in Klf13 −/ ... KLF2 is expressed in quiescent T cells and is down-regulated soon after activation (Buckley et al., 2001; Kuo et al., 1997). In contrast, KLF13 is not expressed in resting T cells but is produced within 24–48 h of activation through the T cell receptor (Song et al., 2002). WebHere we found that the KLF2 transcription factor serves to restrain Tfh cell generation. Induced KLF2 deficiency in activated CD4 + T cells led to increased Tfh cell generation and B cell priming, whereas KLF2 overexpression prevented Tfh cell production.
