Abstract

N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) is a natural tetrapeptide with anti-inflammatory and antifibrotic properties. Its effect on salt-sensitive (SS) hypertension is unknown. We hypothesized that in Dahl SS rats on high-salt (HS) diet, Ac-SDKP prevents loss of nephrin expression and renal immune cell infiltration, leading to a decrease in albuminuria, renal inflammation, fibrosis, and glomerulosclerosis. To test this, Dahl SS rats and consomic SS13BN controls were fed either a low-salt (0.23% NaCl) or HS (4% NaCl) diet and treated for 6 weeks with vehicle or Ac-SDKP at either low or high dose (800 or 1600 μg/kg per day, respectively). HS increased systolic blood pressure in SS rats (HS+vehicle, 186±5 versus low salt+vehicle, 141±3 mm Hg; P
