Acid-sensing ion channel 1a regulates the survival of nucleus pulposus cells in the acidic environment of degenerated intervertebral discs
Objective(s): Activation of acid-sensing ion channel 1a (ASIC1a) is responsible for tissue injury caused by acidosis in nervous systems. But its physiological and pathological roles in nucleus pulposus cells (NPCs) are unclear. The aim of this study is to investigate whether ASIC1a regulates the survival of NPCs in the acidic environment of degenerated discs. Materials and Methods: NPCs were i...
متن کاملInhibition of human acid-sensing ion channel 1b by zinc.
Acid-sensing ion channel 1b (ASIC1b) is expressed in peripheral sensory neurons and has been implicated in nociception. Understanding the modulation of ASIC1b will provide important insight into how ASIC1b contributes to pain sensation. In our previous study, we showed that zinc, an important modulator of pain sensation, reduces rat ASIC1b current. However, rat ASIC1b shows several important di...
متن کاملPt718. Histamine Selectively Potentiates Acid-sensing Ion Channel 1a
Although acid-sensitive ion channels (ASICs) play an important role in brain functions, the exact mechanism of their physiological activation remain unclear. A possible answer to the intriguing question is that some presently unknown endogenous ligand(s) positively modulate ASICs and enhance their responses to physiologically significant level. In the present work we found that histamine select...
متن کاملActivation of acid-sensing ion channel 1a (ASIC1a) by surface trafficking.
Acid-sensing ion channels (ASICs) are voltage-independent Na(+) channels activated by extracellular protons. ASIC1a is expressed in neurons in mammalian brain and is implicated in long term potentiation of synaptic transmission that contributes to learning and memory. In ischemic brain injury, however, activation of this Ca(2+)-permeable channel plays a critical role in acidosis-mediated, gluta...
