Osteopontin attenuates inflammation via JAK2/STAT1 pathway in hyperglycemic rats after intracerebral hemorrhage.

ABSTRACT: Acute intracerebral hemorrhage (ICH) complicated by hyperglycemia is associated with aggravation of post-stroke inflammation, leading to exacerbation of brain edema and predicting poor neurological outcomes and higher mortality of patients. Osteopontin (OPN) is a neuroprotective glycoprotein, which is able to attenuate brain injury induced by hemorrhagic stroke. In the current study we investigated whether OPN will decrease the inflammatory post-ICH response as well as attenuate brain edema and neurological deficits in hyperglycemic rats. We employed a collagenase model of ICH on male Sprague-Dawley rats (n = 148) rats and 50% of Dextrose was injected intraperitoneally (i.p) 3 h after ICH (ICH + HG). Intranasal administration of recombinant OPN (rOPN) was performed 1 h after ICH. The devel
