چکیده

A considerable body of evidence has revealed that interstitial cells of Cajal (ICC), identified with c-Kit-immunoreactivity, act as gut pacemaker cells, with spontaneous Ca(2+) activity in ICC as the probable primary mechanism. Namely, intracellular (cytosolic) Ca(2+) oscillations in ICC periodically activate plasmalemmal Ca(2+)-dependent ion channels and thereby generate pacemaker potentials. This review will, thus, focus on Ca(2+)-associated mechanisms in ICC in the gastrointestinal (GI) tract, including auxiliary organs.

O23: Modulation of Pacemaker Channels and Rhythmic Thalamic Activity by Demyelination and Inflammatory Cytokines

The thalamus is a central element for the generation of rhythmic oscillatory activity under physiological and pathophysiological conditions. Especially slow oscillations in the delta and theta frequency band which normally occur during slow-wave sleep are associated with a number of neuropsychiatric conditions if they occur during wakefulness and may be the basis for the generation of character...

Clotrimazole-sensitive K+ currents regulate pacemaker activity in interstitial cells of Cajal.

Interstitial cells of Cajal (ICC) are pacemaker cells for gut peristaltic motor activity. Compared with cardiac pacemaker cells, little is known about mechanisms that regulate ICC excitability. The objective of the present study was to investigate a potential role for clotrimazole (CTL)-sensitive K currents (I(CTL)) in the regulation of ICC excitability and pacemaker activity. ICC were studied ...

Beating to time: calcium clocks, voltage clocks, and cardiac pacemaker activity.

THE HEARTBEAT ARISES in the sinoatrial node (SAN) and then spreads throughout the heart. SAN function is therefore essential for normal cardiac physiology. The function of the SAN decreases with age, and this has been correlated with changes of ion channel expression (12). It is therefore of great importance to understand the mechanisms responsible for normal pacemaker activity in the SAN. Writ...

Erosive Pressure Dermatitis Associated with Cardiac Pacemaker

Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...

Gut pacemaker cells: the interstitial cells of Cajal (ICC).

This review will focus on the pacemaker mechanisms underlying gastrointestinal autonomic rhythmicity in an attempt to elucidate the differences and similarities between the pacemaker mechanisms in the heart and gut. Interstitial cells of Cajal (ICC) form networks that are widely distributed within the submucosal (ICC-SM), intra-muscular (ICC-IM, ICC-DMP) and inter-muscular layers (ICC-MY) of th...
