CCL2 mediates early renal leukocyte infiltration during salt-sensitive hypertension.

ABSTRACT: Studies examining mechanisms of Dahl salt-sensitive (SS) hypertension have implicated the infiltration of leukocytes in the kidneys, which contribute to renal disease and elevated blood pressure. However, the signaling pathways by which leukocytes traffic to the kidneys remain poorly understood. The present study nominated a signaling pathway by analyzing a kidney RNA sequencing data set from SS rats fed either a low-salt (0.4% NaCl) diet or a high-salt (4.0% NaCl) diet. From this analysis, chemokine (C-C motif) ligand 2 (CCL2) and chemokine (C-C motif) receptor 2 (CCR2) were nominated as a potential pathway modifying renal leukocyte infiltration and contributing to SS hypertension. The functional role of the CCL2/CCR2 pathway was tested by daily administration of CCR2 antagonist (RS-10289
