GNAI1 and infection: Because of the above facts, our results indicate that the reduction of HO-I mRNA at the level of 52%–69% in rabbit organs (liver, kidneys, spleen) after infection with L. europaeus GI.1 and GI.2 genotypes does not protect cells against oxidative damage but, on the contrary, may intensify, which is consistent with the results of experimental studies on various animal models (Choi and Alam, 1996; Yachie, 2021).
