Functional KCa3.1 K+ channels are required for human lung mast cell migration.
BACKGROUND Mast cell recruitment and activation are critical for the initiation and progression of inflammation and fibrosis. Mast cells infiltrate specific structures in many diseased tissues such as the airway smooth muscle (ASM) in asthma. This microlocalisation of mast cells is likely to be key to disease pathogenesis. Human lung mast cells (HLMC) express the Ca2+ activated K+ channel K(Ca)...
متن کاملFunctional Hair Cell Mechanotransducer Channels Are Required for Aminoglycoside Ototoxicity
Aminoglycosides (AG) are commonly prescribed antibiotics with potent bactericidal activities. One main side effect is permanent sensorineural hearing loss, induced by selective inner ear sensory hair cell death. Much work has focused on AG's initiating cell death processes, however, fewer studies exist defining mechanisms of AG uptake by hair cells. The current study investigated two proposed m...
متن کاملAstrocyte Na+ channels are required for maintenance of Na+/K(+)-ATPase activity.
Astrocytes in vitro and in situ have been shown to express voltage-activated ion channels previously thought to be restricted to excitable cells, including voltage-activated Na+, Ca2+, and K+ channels. However, unlike neurons, astrocytes do not generate action potentials, and the functional role of voltage-activated channels in astrocytes has been an enigma. In order to study the function of Na...
متن کاملK channels are expressed early in human T-cell development.
Mature human T lymphocytes proliferate in response to the mitogen phytohemagglutinin (PHA), but immature thymocytes lacking the T3 receptor (T3- thymocytes) do not. Because functioning K channels are required for proliferation of mature T cells, we asked whether immunoincompetent T3- thymocytes lack normal K channels. We report that T3- thymocytes have a K+ current similar to that of mature per...
متن کاملK(ATP)(+) channels, nitric oxide, and adenosine are not required for local metabolic coronary vasodilation.
The role of ATP-sensitive K(+) (K(ATP)(+)) channels, nitric oxide, and adenosine in coronary exercise hyperemia was investigated. Dogs (n = 10) were chronically instrumented with catheters in the aorta and coronary sinus and instrumented with a flow transducer on the circumflex coronary artery. Cardiac interstitial adenosine concentration was estimated from arterial and coronary venous plasma c...
