The Cellular Signaling and Regulatory Systems (CSRS) Study Section reviews applications that focus on a fundamental understanding of molecular mechanisms underlying cellular signaling, information processing, homeostasis, and physiology. A distinguishing characteristic of these applications is an emphasis on pharmacological, physiological, and cell biology studies of cell surface receptors including G-protein coupled receptors (GPCRs), ion channel receptors, and enzyme-linked receptors and their regulation, signaling pathways and networks and the coordination of processes, including those regulating cell growth, proliferation, differentiation, and death. Proposed investigations will typically include cell biological, molecular, biochemical, and morphologic approaches and employing various model systems including but not limited to different cell types, yeast, flies, worms, frogs, plants, cultured cells, and mice.
The membership panel is a list of chartered members only.
