Our data from bladder and other cancer types (colorectal, prostate, and ovarian cancers) [51,108,109,110] demonstrated that high COX2 levels are associated with the suppression of CTL-attracting chemokines and the overexpression of Treg attractants and that its suppression can promote selectively enhanced attraction of type-1 immune cells while inhibiting Treg and MDSC attraction [103]. The gene discussed is PTGS2; the disease is cancer.
