Abstract
Inherited retinal degenerations (IRDs) are a genetically heterogeneous group of disorders characterized by the progressive loss of photoreceptor cells. Despite this heterogeneity in the disease-causing mutation, common underlying mechanisms promoting photoreceptor cell death may be present. Dysregulation of photoreceptor cyclic nucleotide signaling may be one such common feature differentiating healthy from diseased photoreceptors. Here we review evidence that elevated retinal cAMP levels promote photoreceptor death and are a common feature of numerous animal models of IRDs. Improving our understanding of how cAMP levels become elevated and identifying downstream effectors may prove important for the development of therapeutics that will be applicable to multiple forms of the disease.
