CD8A and androgen insensitivity syndrome: On the basis of the analysis of the four CD8+ GZMK+ T subsets as well as the NIHSS and BI scores before and after treatment, we identified significant positive correlations between C04 subset frequencies and NIHSS scores in AIS patients both before (r = 0.523, P < 0.001) and after treatment (r = 0.402, P = 0.001) (Fig. 3G, H).
