CD36 deletion improves recovery from spinal cord injury.

ABSTRACT: CD36 is a pleiotropic receptor involved in several pathophysiological conditions, including cerebral ischemia, neurovascular dysfunction and atherosclerosis, and recent reports implicate its involvement in the endoplasmic reticulum stress response (ERSR). We hypothesized that CD36 signaling contributes to the inflammation and microvascular dysfunction following spinal cord injury. Following contusive injury, CD36(-/-) mice demonstrated improved hindlimb functional recovery and greater white matter sparing than CD36(+/+) mice. CD36(-/-) mice exhibited a reduced macrophage, but not neutrophil, infiltration into the injury epicenter. Fewer infiltrating macrophages were either apoptotic or positive for the ERSR marker, phospho-ATF4. CD36(-/-) mice also exhibited significant improvements in inj
