In this review, we describe the current knowledge on calcium signaling pathways in interstitial cells with a special focus on interstitial cells of Cajal (ICCs), interstitial Cajal-like cells (ICLCs), and telocytes. In detail, we present the generation of Ca2+ oscillations, the inositol triphosphate (IP₃)/Ca2+ signaling pathway and modulation exerted by cytokines and vasoactive agents on calciu...

BACKGROUND Idiopathic slow transit constipation is one of the most severe and often intractable forms of constipation. As motor abnormalities are thought to play an important pathogenetic role, studies have been performed on the colonic neuroenteric system, which rules the motor aspects of the viscus. AIMS We hypothesised that important neuropathological abnormalities of the large bowel are p...

Interstitial cells of Cajal (ICC) are pacemakers that generate electric waves recorded from the gut and are important for intestinal motility. The aim of the study was to evaluate the distribution of interstitial cells of Cajal in colon specimens from patients with idiopathic chronic pseudo-obstruction and other non-tumoral colon disorders as compared with samples from normal colon. The distrib...

Patients with long-standing diabetes commonly suffer from gastric neuromuscular dysfunction (gastropathy) causing symptoms ranging from postprandial bloating to recurrent vomiting. Autonomic neuropathy is generally believed to be responsible for diabetic gastropathy and the underlying impairments in gastric emptying (gastroparesis) and receptive relaxation, but the specific mechanisms have not ...
