['CCR5 is expressed on infiltrating T cells in hypertensive mice and CCR5 antagonists reduce hypertension making CCR5 an interesting target in treatment of hypertension.', 'To evaluate the role of CCR5 in hypertensive renal and cardiac end-organ damage, we induced hypertension with desoxycorticosterone acetate (DOCA) and angiotensin II (Ang II) in wild-type (WT) and CCR5-deficient mice.', 'CCR5 expression was increased in renal cortex and cardiac tissue as measured by quantitative PCR. Systolic blood pressure and renal function did not differ between hypertensive CCR5(-/-) and WT mice. DOCA + Ang II induced massive albuminuria and glomerular injury but no difference was found between CCR5(-/-) and WT mice. In addition, no difference was found for renal inflammation as measured by infiltrating T cells, macrophages, and CCL2 expression. The renal expression of the CCR5 ligands, CCL3, and CCL5 was increased in the kidney of hypertensive mice. For CCL3 the increase was significantly higher in CCR5(-/-) than in WT mice. DOCA + Ang II induced cardiac damage as assessed by heart weight, cardiac fibrosis as well as expression of fetal and matrix components but no significant difference was found between CCR5(-/-) and WT mice.'] Does cCR5 deficiency reduce hypertensive end-organ damage in mice?
