Abstract:
Taste-signaling proteins, which are expressed throughout the digestive tract, are involved in regulating metabolism and immunity. This study aimed to determine if these genes are expressed and altered in jejunal tissues from patients with extreme obesity who received bariatric surgery. Reverse transcription polymerase chain reaction revealed that phospholipase C beta 2 and transient receptor potential channel M5 expression was downregulated in the jejunum of patients with a body mass index above 50, whereas gustducin expression remained unchanged. Our data suggest that taste-signaling dysregulation might contribute to obesity.

Gastric Phase of Digestion
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...
