Association of dipeptidyl peptidase-4 with Alzheimer's disease: A new therapeutic prospect.
Alzheimer's disease (AD) is the most common disease associated with cognitive dysfunction, which is closely associated with type 2 diabetes mellitus (T2DM) in clinical manifestations, pathological changes and prevention. Inhibition of dipeptidyl peptidase 4 (DPP-4) can lower blood glucose levels by stimulating insulin secretion. Besides, it can affect cognitive function through the neuroprotective effect of DPP-4 substrates, such as glucose-dependent insulin peptide and glucagon-like peptide-1, the proteolytic effect on amyloid-β and the protective effect on neuronal structure. This review discusses the relationship between cognitive impairment in T2DM and in AD, summarizes the effect of DPP-4 inhibitor (DPP-4i) on improving cognitive impairment in these two diseases based on the current studies. Given the lack of clinical randomized trials that evaluate the effect of DPP-4i on AD, this review is expected to provide preclinical evidence for DPP-4i as a potential therapy for the treatment and prevention of AD.
期刊介绍：
The Journal of Alzheimer''s Disease (JAD) is an international multidisciplinary journal to facilitate progress in understanding the etiology, pathogenesis, epidemiology, genetics, behavior, treatment and psychology of Alzheimer''s disease. The journal publishes research reports, reviews, short communications, hypotheses, ethics reviews, book reviews, and letters-to-the-editor. The journal is dedicated to providing an open forum for original research that will expedite our fundamental understanding of Alzheimer''s disease.
