Does the 2-monoacylglycerol moiety of dietary fat appear to be responsible for the fat-induced release of GLP-1 in humans?
Under our study conditions, 2-OG and GPR119 activation can fully explain the olive oil-induced secretion of GLP-1, PYY, and neurotensin. In contrast, both oleic acid and 2-OG contributed to the GIP response. Dietary butyrate did not stimulate gut hormone secretion. Olive oil-derived oleic acid seems to be fully responsible for olive oil-induced CCK secretion. This trial was registered at clinicaltrials.gov as NCT02264951.
These results indicate that TYLCV tends to induce SA-regulated plant defense against B but SA-regulated plant defense against Q was reduced. In other words, Q may have a mutualistic relationship with TYLCV that results in the reduction of the plant's defense response.
