An integrin inhibiting molecule decreases oxidative damage and improves neurological function after spinal cord injury.

Our previous studies have shown that treatment with an alpha4beta1 integrin blocking antibody after spinal cord injury (SCI) in rats decreases intraspinal inflammation and oxidative damage, improving neurological function. Here, we studied effects of a high affinity small molecule alpha4beta1 inhibitor, BIO5192. First, rats were treated intravenously with BIO5192 (10 mg/kg) or with vehicle (controls) to assess effects of integrin blockade for 24 h or 72 h after thoracic clip-compression SCI.
