Figure 1 (Left) Recovery of tTFH and CD4+ T-cells/μL) after HSCT. (Right) Frequencies of cTFH in the CD4+ T-cell gate beginning 2 months after HSCT. Number of patients analyzed for each time point is indicated below the graph. Dashed lines represent the median values from 11 Healthy Donors (90% CI plotted in light red and light grey for the respective population).

Figure 2 Assessment of B-tell helper function in cTFH subsets. cTFH (CD4+CD45RA-CXCR5+) and non-cTFH (CD4+CD45RA-CXCR5-) T cell subsets were purified by flow cytometric cell sorting. IgG (left) and IgM (Right) production was measured in supernatants? after 12-day co-culture of purified T-cell subsets with naive B-cells stimulated with Staphylococcal Enterotoxin B.
