RT info:eu-repo/semantics/article T1 The role of Ca2+ signaling in aging and neurodegeneration: Insights from caenorhabditis elegans models A1 Álvarez Martín, Javier A1 Álvarez Illera, María Pilar A1 García Casas, Paloma A1 Fonteriz García, Rosalba Inés A1 Montero Zoccola, María Teresa K1 Calcium K1 Calcio K1 Caenorhabditis elegans K1 Neurodegeneration K1 Neurodegeneración AB Ca2+ is a ubiquitous second messenger that plays an essential role in physiological processes such as muscle contraction, neuronal secretion, and cell proliferation or differentiation. There is ample evidence that the dysregulation of Ca2+ signaling is one of the key events in the development of neurodegenerative processes, an idea called the “calcium hypothesis” of neurodegeneration. Caenorhabditis elegans (C. elegans) is a very good model for the study of aging and neurodegeneration. In fact, many of the signaling pathways involved in longevity were first discovered in this nematode, and many models of neurodegenerative diseases have also been developed therein, either through mutations in the worm genome or by expressing human proteins involved in neurodegeneration (β-amyloid, α-synuclein, polyglutamine, or others) in defined worm tissues. The worm is completely transparent throughout its whole life, which makes it possible to carry out Ca2+ dynamics studies in vivo at any time, by expressing Ca2+ fluorescent probes in defined worm tissues, and even in specific organelles such as mitochondria. This review will summarize the evidence obtained using this model organism to understand the role of Ca2+ signaling in aging and neurodegeneration.
