A new Alzheimer's disease interventive strategy: GLP-1
Perry TA, Greig NH.. Current drug targets, 2004-08-01
Topic: Gut, metabolism and diet
Glucagon-like peptide-1 (7-36)-amide (GLP-1) is an endogenous 30-amino acid gut peptide, which binds at the GLP-1 receptor coupled to the cyclic AMP second messenger pathway. GLP-1 receptor stimulation enhances pancreatic islet beta-cell proliferation, glucose-dependent insulin secretion and lowers blood glucose and food intake in patients with type 2 diabetes mellitus. Not limited to the pancreas, the chemoarchitecture of GLP-1 receptor distribution in the brain of rodents and humans correlates with a central role for GLP-1 in the regulation of food intake. However emerging evidence suggests that stimulation of neuronal GLP-1 receptors plays an important role in regulating neuronal plasticity and cell survival. GLP-1 has been documented to induce neurite outgrowth and to protect against excitotoxic cell death and oxidative injury in cultured neuronal cells. Moreover, GLP-1 and exendin-4, a naturally occurring more stable analogue of GLP-1 that likewise binds at the GLP-1 receptor, were shown to reduce endogenous levels of amyloid-beta peptide (Abeta) in mouse brain and to reduce levels of beta-amyloid precursor protein (betaAPP) in neurons. Collectively these data suggest that treatment with GLP-1 or a related peptide beneficially affects a number of the therapeutic targets associated with Alzheimer's disease (AD). Although much remains to be elucidated with regards to the downstream signaling pathways involved in the pro-survival properties of GLP-1, modulation of calcium homeostasis may be critical. This review will consider the potential therapeutic relevance of GLP-1 to CNS disorders, such as AD.
Key findings
- However emerging evidence suggests that stimulation of neuronal GLP-1 receptors plays an important role in regulating neuronal plasticity and cell survival.
- Collectively these data suggest that treatment with GLP-1 or a related peptide beneficially affects a number of the therapeutic targets associated with Alzheimer's disease (AD).

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
