Many studies have shown that apoptosis serves an important role in VaD occurrence; therefore, inhibition of apoptosis may contribute to the recovery of neurological function after VaD occurrence. Cerebroprotein hydrolysate-I (CH-I), a neuropeptide preparation which consists of several amino acids and small molecular peptides as the main active constituent, is extracted using a method similar to cerebrolysin (CBL) which has neuroprotective and neurotrophic effects.Methods: In the present study, a VaD model which was constructed using bilateral common carotid artery occlusion (BCCAO) in Kunming mice was applied to examine the neuroprotective effects of CH-I.Results: The results show that CH-I treatment could attenuate the decrease of learning and memory ability, cell apoptosis in the hippocampal CA1 region and inhibit the activation of caspase-3 and caspase-9 in VaD mice. Furthermore, CH-I treatment could also upregulate Bcl-2 protein levels and activate PI3K and Akt.Discussion: We speculate that CH-I may induce a neuroprotective effect activating PI3K/Akt signaling pathway in VaD mice.Keywords: vascular dementia, cerebroprotein hydrolysate-I, apoptosis, PI3K/AktWu XLiu YZhu LWang YRen YCheng BRen LGe KLi HDove Medical Pressarticlevascular dementiacerebroprotein hydrolysate-iapoptosispi3k/aktNeurosciences.
