Abstract
To investigate immunoregulatory mechanisms of Sertoli cells in the testis in vitro and in vivo, we utilized our well-characterized Ureaplasma Urealyticum (UU)-induced model. We investigated the expressions of IL-1alpha, IL-6, TGF-beta, FasL and ZNF265 at the first, second and third weeks post-infection. During recovery from inflammation and with the help of negative regulators TGF-beta and FasL, the high levels of IL-1alpha and IL-6 expressions were observed in the early stages of the infection, and decreased gradually in the later weeks both in vitro and in vivo. The trend of varied expression of ZNF265 was similar to those of TGF-beta and FasL in vitro and in vivo for Sertoli cells infected with UU.
