Many neurodegenerative diseases, including Alzheimer’s Disease, are associated with ER stress. It is suggested that plasma membrane channels contribute to the increased ionic influx and subsequent cell death in response to ER stress. Pannexin channels, which have been implicated in various pathophysiological conditions, are a suitable candidate for facilitating this response. However, mechanisms of pannexin channel activation are poorly defined. I investigated the potential regulation of pannexin activity by the ER stress sensor, STIM. It was hypothesized that pannexin channel activation during ER stress is contingent on the recruitment of STIM proteins. In neurons, pannexin activation was observed in response …
