TGFB2 and posterior cortical atrophy: Similarly, another recent study [50] found strong correlation between microbe (e.g. Delftia acidovorans, Gardnerella vaginalis) abundance in PCa tissue and regulatory T-cells, as well as with down-regulated immune-associated genes including LPCAT2, TL3, and TGFB2, indicating an immuno-suppressive tumor environment associated with the PCa microbiota.
