Oligophrenin-1: the link between calcium-regulated exocytosis and compensatory endocytosis in neuroendocrine cells

Résumé

In neuroendocrine cells, hormones and neuropeptides are released from large-dense core vesicles (secretory granules) by calcium-regulated exocytosis. Following exocytosis, compensatory uptake of membrane is required to maintain membrane homeostasis and allow recycling of secretory vesicle membranes. How these cells initiate and regulate this compensatory endocytosis remains poorly understood. Our recent data suggests that oligophrenin-1 (OPHN1) is a link coupling calcium-regulated exocytosis to compensatory endocytosis of secretory granules in the adrenal chromaffin cells (Houy et al., 2015, J Neurosci. 2015, 35:11045-55). Here, we highlight the major evidence and discuss how OPHN1 could couple these two processes.
