WebTfh cells marked by high levels of CXCR5, PD-1, and Bcl-6 expression are specialized to support B-cell response in germinal centers that are essential for class switching … Web21 Jun 2024 · CXCR5 is one of the most widely used markers to identify Tfh cells. Initially, OX40 in vitro was reported to induce CXCR5 mRNA transcription in activated mouse T cells, indicating that OX40 signaling may promote differentiation of Tfh cells by upregulating CXCR5 expression ( 71, 72 ).
