WebFeb 11, 2016 · Circulating memory T follicular helper subsets, Tfh2 and Tfh17 are found to be aberrantly regulated in many autoimmune diseases. However, their roles in the pathogenesis of GBS are still unclear. WebMar 24, 2024 · Follicular T helper (Tfh) and regulatory (Tfr) cells are distinct subsets of CD4 + T lymphocytes, regulating humoral immune responses in the germinal center. It is widely accepted that dysregulated Tfh and Tfr cells are associated with autoimmunity. Here, we evaluated the frequencies of circulating CXCR5 + PD-1 + Tfh (cTfh) and …
WebApr 20, 2024 · CD4 + T cells play a crucial role in B cell responses. T follicular helper (Tfh) cells were recently described as a distinct subset of CD4 + T cells with specialized B cell helper functions. Tfh cells express abundant C-X-chemokine receptor type 5 (CXCR5), which enables homing to B cell follicles. WebSep 7, 2024 · We show that anti-PD-1 therapy induces a population of circulating T follicular helper cells (cTfh) with enhanced B activation capacity, which participates in tumor response to treatment. Anti-PD-1 increases the number of tertiary lymphoid structures (TLS), which correlates with impaired tumor growth.
