GLP-2's intestinal growth-promoting effects were mediated through PI3K-gamma signaling, identifying the specific intracellular pathway by which this gut peptide maintains and repairs the small intestinal lining.

What the researchers found
PI3K-gamma was identified as an essential mediator of GLP-2's intestinal mucosal growth effects, with PI3K-gamma knockout mice showing impaired GLP-2-stimulated mucosal proliferation — mapping the signal transduction for gut peptide-driven intestinal repair.
