GLP-1, on the other hand, is a specific peptide hormone secreted primarily by intestinal L-cells after you eat
ENS neurons can release many neurotransmitters and are closely related to vagus efferent input, forming intrinsic sensorimotor circuits (187, 188)
simultaneously, IBD-related genetic markers (NOD2, IL23R) influence baseline gut barrier function and inflammatory state
Interestingly, the reduced levels of PI(4)P and PI(4,5)P 2 in both rod Igf-1r / and ret Igf-1r / mice suggest that IGF-1R may regulate phosphatidylinositol 4-kinase (PI4K generates PI(4)P from PI), phosphatidylinositol 5-phosphate 4-kinase (PIP4K generates PI4,5P 2 from PI(4)P), and phosphatidylinositol 4-phosphate 5-kinase (PIP5K generates PI (4,5)P 2 from PI(5)P)
Remember this is a PEPTIDE (messenger), not a trans-dermal filler
The next 18 months will determine whether muscle-sparing adjuncts become essential or if next-gen incretin combinations close the gap before the category matures
