Genetic deficiency of adiponectin protects against acute kidney injury.

ABSTRACT: Adiponectin is a multifunctional cytokine that has a role in regulating inflammation. Here we determined whether adiponectin modulates ischemic acute kidney injury. Compared with wild-type mice, adiponectin-knockout mice were found to have lower serum creatinine and less tubular damage or apoptosis following ischemia/reperfusion injury. This latter process was associated with decreased Bax and reduced activation of p53 and caspase-3. Targeted disruption of adiponectin was also found to inhibit the infiltration of neutrophils, macrophages, and T cells into the injured kidneys. This was associated with inhibition of NF-κB activation and reduced expression of the proinflammatory molecules IL-6, TNF-α, MCP-1, and MIP-2 in the kidney after ischemia/reperfusion injury. Wild-type mice engrafted w
