Topic: Brain proteins, microglia and lab models
The anti-obesity drug GLP-1 has been proven to have an impact on central nervous system, while its extremely short half-life greatly limited its use. In this study, our group constructed two engineering strains MG1363-pMG36e-GLP-1 and VNP20009-pLIVE-GLP-1 to continuously express GLP-1, and supplementation of these strains, especially MG1363-pMG36e-GLP-1, had significantly restored the spatial learning and memory impairment of mice caused by LPS (p < 0.05), suppressed glia activation and Aβ accumulation, and downregulated inflammatory expressions of COX-2, TLR-4, TNF-a, and IL-1β. In addition, MG1363-pMG36e-GLP-1 had significantly blocked the translocation of NF-κB signal and inhibited the phosphorylation of redox-sensitive cytoplasmic signalings of MAPKs and PI3K/AKT. These data suggest that MG1363-pMG36e-GLP-1 could be used as a safe and effective nonabsorbed oral treatment for neuroinflammation-related diseases such as Alzheimer's disease (AD).

Key findings
- In this study, our group constructed two engineering strains MG1363-pMG36e-GLP-1 and VNP20009-pLIVE-GLP-1 to continuously express GLP-1, and supplementation of these strains, especially MG1363-pMG36e-GLP-1, had significantly restored the spatial learning and memory impairment of mice caused by LPS (p < 0.05), suppressed glia activation and Aβ accumulation, and downregulated inflammatory expressions of COX-2, TLR-4, TNF-a, and IL-1β.
- In addition, MG1363-pMG36e-GLP-1 had significantly blocked the translocation of NF-κB signal and inhibited the phosphorylation of redox-sensitive cytoplasmic signalings of MAPKs and PI3K/AKT.
- These data suggest that MG1363-pMG36e-GLP-1 could be used as a safe and effective nonabsorbed oral treatment for neuroinflammation-related diseases such as Alzheimer's disease (AD).

Study details
- Evidence strengthLow
How this study scored 38/100
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 22 of the 58 points we could judge it on, which is 38 out of 100.
