However, we did not observe significant differences in the frequencies of central memory (CM) (CD45RA-CD45RO+CD27+), effector memory (EM) (CD45RA-CD45RO+CD27-), naïve (CD45RA+CD45RO-CD27+) and effector (CD45RA+CD45RO-CD27-) CD8 T cells, nor MAIT cells (TCRVα7.2+CD161+) between psoriasis patients and healthy controls (Figures 1C, D). Here, CD8A is linked to psoriasis.
