Fig. 3. The relevance of IFN-I signaling to MAIT cell dysfunction in HIV-1 infection.

(A) The level of IFN-α, IFN-β, IP-10, and IL-10 in the plasma was detected by enzyme-linked immunosorbent assay (ELISA). (B) Correlation between the proportion of IFN-γ⁺ or GzmB⁺ MAIT cells in response to PFA-fixed E. coli and the level of IP-10 in the plasma from HIV-1–infected patients receiving (blue) or not receiving (red) ART. P values were determined by Spearman rank correlation tests.
