Germinal matrix hemorrhage is induced by stereotaxic injection of collagenase into the germinal matrix of P7 Sprague-Dawley rats. Hemoglobin assay, western blot, immunofluorescence and neurobehavioral tests were used to test the effects of BLVRA on hematoma resolution and anti-inflammatory response. We showed that BLVRA triggered a signaling cascade that ameliorated post-hemorrhagic neurological deficits in both short-term and long-term neurobehavioral tests in a GMH rat model. Specifically, BLVRA inhibited toll-like receptor 4 (TLR4) expression by translocating to the nucleus in an endothelial nitric oxide (eNOS)/nitric oxide (NO)-dependent manner. BLVRA also induced the upregulation of CD36 scavenger receptor level in microglia/microphages, of which the prominent role is to enhance hematoma resolution. However, the beneficial effects of BLVRA were abolished with the knockdown of eNOS, indicating that the eNOS/NO system is an important downstream factor of BLVRA. Our results demonstrate a mechanism of BLVRA modulating hematoma resolution and suppressing inflammation through eNOS/NO/TLR4 pathway in the GMH rat model.
