Supplementary MaterialsAdditional file 1: Figure S1. for determining the expression of PD-1, ICOS, IL-21, and pSTAT3. The cut off for PD-1 (A), ICOS (B), IL-21 (C), or pSTAT3 (D) positivity in CD4+CXCR5+ T cells was determined based on fluorescence minus one (FMO) and isotype control subjects of PD-1, ICOS, IL-21, or pSTAT3.
