GLP-1 receptor activation inhibits beta-cell apoptosis through cAMP/PKA and PI3K/Akt signaling pathways, protecting beta-cells from cytokine and fatty acid-induced death.
GLP-1 helps beta-cells survive stress by activating survival pathways (Akt and CREB). This protection may help maintain insulin production in the face of metabolic stress.
GoodSupportsHIGH confidence
GLP-1 receptor activation also promotes cell survival in beta-cells and neurons via increased levels of cAMP leading to cAMP response element binding protein activation, enhanced insulin receptor substrate-2 activity and, ultimately, activation of Akt.
Why this rating
Supported by multiple in vitro and in vivo studies cited in the review.
