However, the results from TIMER showed that USP13 expression was positively correlated with the infiltration levels of B cells (R = 0.377, p < 0.001), CD8+ T cells (R = 0.544, p < 0.001), macrophages (R = 0.323, p < 0.001), neutrophils (R = 0.302, p < 0.001) and dendritic cells (R = 0.37, p < 0.001), as shown in Fig. 7Q. We then analyzed the association between the expression of USP13 and immune inhibitors (Fig. 8A), immunostulators (Fig. 8B), chemokines (Fig. 8C) and major histocompatibility complex (MHC) (Fig. 8D) in PCa based on TCGA_PRAD. The gene discussed is CD8A; the disease is posterior cortical atrophy.
