Long-term exposure of mice to mild heat (34°C±1°C) confers neuroprotection against traumatic brain injury (TBI); however, the underling mechanisms are not fully understood. Heat acclimation (HA) increases hypothalamic angiotensin II receptor type 2 (AT2) expression and hypothalamic neurogenesis. Accumulating data suggest that activation of the brain AT2(More)
Preventing relapse to drug use is a major challenge for the treatment of drug addiction. Environmental cues are among the major determinants of relapse in abstinent cocaine users. The protein kinase M ζ (PKMζ) is involved in the generation and maintenance of long-term potentiation and is critical in memory storage. Here we show that inhibition of PKMζ in(More)
Despite years of research, no effective therapy is yet available for the treatment of traumatic brain injury (TBI). The most prevalent and debilitating features in survivors of TBI are cognitive deficits and motor dysfunction. A potential therapeutic method for improving the function of patients following TBI would be to restore, at least in part,(More)
Nerve growth factor (NGF) is a neurotrophin required for differentiation, development, and survival of the sympathetic nervous system, with many of its biological effects being mediated via trkA receptors. There is a need for a standard quantitative bioassay for NGF, to be used in basic research and in pharmaceutical studies. The objective of the present(More)
Snake venoms are a very abundant source of nerve growth factors (NGF). NGFs of Elapidae showing 65% sequence homology with mouse or human NGF, while the Viperidae NGF shows N-glycosylation (Asn-21) typical of these mammalian NGFs. Snake NGF-induced neurite outgrowth (neurotropic activity) was measured in the past by using PC12 cell or dorsal root ganglion(More)
Cognitive deficits, especially memory loss, are common following many types of brain insults which are associated with neuroinflammation, although the underlying mechanisms are not entirely clear. The present study aimed to characterize the long-term cognitive and behavioral impairments in a mouse model of neuroinflammation in the absence of other insults(More)
Angiotensin II receptor type 2 (AT2) agonists have been shown to limit brain ischemic insult and to improve its outcome. The activation of AT2 was also linked to induced neuronal proliferation and differentiation in vitro. In this study, we examined the therapeutic potential of AT2 activation following traumatic brain injury (TBI) in mice, a brain pathology(More)
