Furthermore, for the KTR, 40% (8/20), 50% (10/20), and 60% (12/20) of results were out of CD4+, CD8+ T cell, and NK cell function RIs, respectively; for the infants, 70% (14/20), 70% (14/20), and 75% (15/20) of results were out of CD4+, CD8+ T cell, and NK cell function RIs, respectively; for the SLE patients, 45% (9/20), 50% (10/20), and 65% (13/20) of results were out of CD4+, CD8+ T cell, and NK cell function RIs, respectively (Figure 7B). Here, CD8A is linked to systemic lupus erythematosus.
