WebHe et al 26 proposed that circulating Tfh cells can be categorized as effector memory cells (Tfh-em) and central memory cells (Tfh-cm) on the basis of PD-1 and CCR7 expression. Tfh-em cells are defined as PD-1 + CXCR5 + BCL6 − ICOS + CCR7 low cells, which are similar to pre-Tfh cells at the activated stage, and Tfh-cm cells are PD-1 − CXCR5 ... Web22 Nov 2024 · T peripheral helper (Tph) cells represent a T cell population that stimulates B cell responses within peripheral tissues. Like T follicular helper (Tfh) cells, PD-1 hi CXCR5 − CD4 + Tph cells produce IL-21 and CXCL13, yet these cells differ from Tfh cells in expression of both transcription factors and chemokine receptors.

Therefore, circulating … WebHowever, GS-986–stimulated pDCs from CHB patients expressed OX40L and produced IL-6 and IL-12, resulting in the induction of IL-21–producing Tfh cells (CXCR5 + PD-1 + CD4 +) from naïve CD4 + T cells. The Tfh-inducing capacity of GS-986 was reduced in the presence of an anti-OX40L blocking antibody.
