urthermore, TR in enteroendocrine cells may participate in the complex events leading to control of feed intake. For example, dietary carbohydrates and some HIS may increase glucose absorption by stimulating the T1R2 receptor in the gut mucosa which, in turn, triggers active glucose transport through the SGLT1. Porcine sweet TRs have been involved in up-regulating SGLT1 and glucose uptake after stimulation with sucrose, SAC or NHDC in piglet intestinal mucosa (Figures 1 and 2 –Moran et al. 2010-). If these findings would be confirmed we could speculate in HIS to be involved in improving glucose uptake but also to initiate an orexigenic response through GLP1, thus potentially enhancing feed intake in piglets through post-ingestive events.
