Reactivity of the Immune System and Activities of PPARα and PPARγ in the Liver under Conditions of LPS-Induced Acute Infl ammatory Response in Hypertensive ISIAH Rats

  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

The effects of LPS from E. coli on DNA-binding activities of PPARα and PPARγ in the liver and immune system parameters of were studied in hypertensive ISIAH rats and normotensive WAG rats. In ISIAH rats characterized by low basal level of PPARα, PPARγ, and HDL, the response of the peripheral immune system compartment to LPS was more pronounced and was not associated with decrease in DNA-binding activities of PPARα observed in WAG. Proinfl ammatory stimulus did not induce proliferative changes in the thymus of ISIAH rats, which can refl ect impaired relationships between the central and peripheral organs of the immune system. The character of regulatory interactions between PPARα and immune cells can differ in various rat strains and depend on initial PPARα activity, HDL level, specifi c features of immune status, resistance to stress, and hormonal and metabolic background.
