New Publication in Gastro Hep Advances (June 2024)
1030 412 DaCosta Lab

We are pleased to announce a new publication, “Glucagon-like-protein-2 stimulates lacteal contractility and enhances chylomicron transport in the presence of an intact enteric nervous system,” in Gastro Hep Advances (June 2024). Authors: Majid Mufaqam Syed-Abdul, Lili Tian, Timothy Samuel, Alex Wong, Young-Kwon Hong, Ralph S. Dacosta, Gary F. Lewis ABSTRACT Background and Aims: Secretion and transport of intestinal chylomicrons (CM) via lymphatics to the blood circulation is stimulated primarily by fat ingestion, whereas several other factors have also been shown to play important roles in regulating CM secretion rate. Amongst these factors, active regulation of lymphatic pumping has not been…
