The Role Of Astrocytic Calcineurin Activation And Downstream Signaling In Neurodegenerative Diseases, Melanie M. Pleiss

Theses and Dissertations--Pharmacology and Nutritional Sciences

Calcineurin (CN) is a calcium (Ca²⁺)-sensitive serine/threonine protein phosphatase that plays a significant role in several cell signaling pathways, and has been implicated in many neurodegenerative diseases including Alzheimer’s disease (AD) and vascular cognitive impairment and dementia (VCID). Although normally found in neurons, CN also appears at high levels in activated astrocytes under conditions of injury and disease. To elucidate the role of astrocytic calcineurin signaling in neurodegenerative diseases, our lab has used primary rat astrocytes, transgenic and diet-induced mouse models of dementia, and human tissue biospecimens from confirmed AD and VCID cases.
