Research & Grants
Our research is directed towards, identification and regulation of the molecular mechanisms involved in Ca2+ signaling (TRPC and Orai proteins) in neuronal and non neuronal cells. Define the molecular mechanism involved in their regulation, identify the role of calcium in differential gene expression, and in diseases such as Parkinson’s, Alzheimer, Sjogren’s, Dariers disease and Cancer. We use cutting edge molecular, biochemical, and physiological methods for this exciting research and are also interested in developing technology for early diagnosis of these diseases.
