Summary: The formation of central CD8 T cell memory in response to infection depends on the transcription factor Tcf1 (Tcf7). Tcf1 is expressed at high levels in naive CD8 T cells but downregulated in most CD8 T cells during effector differentiation. The relevance of Tcf1 downregulation for effector differentiation and the signals controlling Tcf1 expression have not been elucidated. https://www.diegojavierfares.com/flash-find-Bushranger-Awning-2-5m-W-x-2-0m-L-2-Year-No-Fuss-Warranty-AW2000-best-save/
