GLP-1-activated PKA inhibits voltage-gated potassium channels, prevents membrane repolarization, and prolongs VDC channel opening to promote Ca 2+ inward currents, contributing to GLP-1 stimulate insulin secretion, and the antagonistic effect of GLP-1R activation on Kv currents in cells requires transactivation of epidermal growth factor receptors, accompanied by signal conduction of cAMP/PKA and phosphatidylinositol-3-kinase (PI3K)/PKC signaling (MacDonald et al., 2003)
Clinically speaking, there is no formal medical definition of microdosing GLP-1. The term generally refers to taking a dose lower than the standard FDA-approved titration schedule for a GLP-1 receptor agonist
