Conditional neuronal membrane potential oscillations have been identified as a potential mechanism to help support or generate rhythmogenesis in neural circuits. A genetically identified population of ventromedial interneurons, called Hb9, in the mouse spinal cord has been shown to generate
Many aldehyde dehydrogenases (ALDHs) have potential potassium-binding sites of as yet unknown structural or functional roles. To explore possible K(+)-specific effects, we performed comparative structural studies on the tetrameric betaine aldehyde dehydrogenase from Pseudomonas aeruginosa (PaBADH) and on the dimeric

We studied principal neurons from canine intracardiac (IC) ganglia to determine whether large-conductance calcium-activated potassium (BK) channels play a role in their excitability. We performed whole cell recordings in voltage- and current-clamp modes to measure ion currents and changes in
Recently, we have found that pressure-induced hemolysis is enhanced by inhibiting water transport via aquaporin-1 (AQP1), as seen in p-chloromercuribenzoate (pCMB)-treated erythrocytes. So, using this method we reinvestigated the functions as AQP1 inhibitors of drugs and chemicals such as acetazolamide
Neurosteroids such as allopregnanolone (Allo) are widely distributed in the brain and may modulate neuronal excitability under physiological or pathological states. Allo modulates GABAA receptor responses, and in this study we investigated the functional effects of Allo on presynaptic GABAA
