چکیده انگلیسی
The transcription factor Krüppel-like factor 4 (KLF4) can activate or repress gene expression in a cell-context dependent manner. We have previously shown that KLF4 inhibits the proliferation of naïve CD8+ T cells in vitro downstream of the transcription factor ELF4. In this work, we describe a novel role of KLF4 in the differentiation of CD8+ T cells upon infection. Loss of KLF4 had minimal effect on thymic T cell development and distribution of mature T cells in the spleen, blood, and lymph nodes. KLF4-deficient naïve CD8+ T cells also displayed normal homeostatic proliferation upon adoptive transfer into lymphopenic hosts. However, activation of KLF4-deficient naïve CD8+ T cells by in vitro TCR crosslink and co-stimulation resulted in increased proliferation. Furthermore, naïve KLF4-deficient OT-I CD8+ T cells generated increased numbers of functional memory CD8+ T cells compared to wild type OT-I CD8+ T cells co-injected in the same recipient in both primary and recall responses to Listeria monocytogenes-OVA. Collectively, our data demonstrate that KLF4 regulates differentiation of functional memory CD8+ T cells while sparing development and homeostasis of naïve CD8+ T cells.
