Eleftheriadis, T.; Liakopoulos, V.; Leivaditis, K.; Antoniadi, G.; Stefanidis, I. (2011)Hemodialysis (HD) patients are particularly predisposed to infections. It seems that the HD procedure per se as well as disturbances in both innate and adaptive immunity significantly contribute to this susceptibility. ... -

Eleftheriadis, T.; Pissas, G.; Antoniadi, G.; Liakopoulos, V.; Stefanidis, I. (2015)Activated T cells rely on aerobic glycolysis and glutaminolysis in order to proliferate and differentiate into effector cells. Therefore, intervention in these metabolic pathways inhibits proliferation. The aim of the ... -
