CD8A and neoplasm: Interestingly, in the tumours that have high levels of STAB1 mRNA, higher infiltration of CTLs is associated with decreased overall survival (upper Kaplan–Meier curves in Fig. 3d) whereas, in the low-STAB1-expressing tumours, higher CTL infiltration is associated with a more favourable overall survival (lower curves in Fig. 3d), suggesting that STAB1 expression levels might indeed correlate with mechanisms that impair the antitumour effector functions of CD8+ T cells.
