We established a murine RAS model by placing a cuff on the right renal artery and treated mice with the p38 inhibitor SB203580 or vehicle for 2 wk. We sought to test the hypothesis that inhibition of p38 MAPK ameliorates chronic renal injury in mice with RAS. However, a potential role of p38 signaling in the development and progression of chronic renal disease in RAS has not been previously defined. In vitro studies have implicated p38 MAPK as a critical intermediate for the production of CCL2. Recent studies have underscored a critical role for CCL2 (MCP-1)-mediated inflammation in the progression of chronic renal damage in RAS and other chronic renal diseases. Renal artery stenosis (RAS) is an important cause of chronic renal dysfunction.

Our data confirm the role of uremic toxicity in the genesis of neurological abnormalities (other than anxiety. In conclusion, we showed that a murine model of CRF is suitable for evaluating uremic toxicity and the associated neurological disorders. Furthermore, neurological test results in non-CRF mice tended to improve in the days following ischemic stroke, whereas the results in CRF mice tended to worsen. Chronic renal failure enhances the severity of ischemic stroke, as evaluated by the infarct volume size in CRF mice after 34 weeks of CRF.
controls after 6 weeks of CRF but was impaired after 10 weeks of CRF. In contrast, CRF mice showed lower levels of anxiety in some tests. We did not observe any significant increases between CRF mice and non-CRF mice in terms of anxiety. In the present study, we examined the impact of CRF on behavior (anxiety, recognition and ischemic stroke severity in a well-defined murine model of CRF.
However, data on the impact of CRF on the cerebral circulatory system are scarce—despite the fact that stroke is the third most common cause of cardiovascular death in people with CRF.
