Cellular signaling is a central focus of research in the Department of Cell Biology. Signal transduction through cell surface receptors, ion channels, and associated proteins exerts both short- and long-term effects across diverse cell types, ultimately shaping fundamental cellular functions. Our research integrates a wide range of experimental systems, from unicellular models to complex multicellular organisms, along with advanced methodologies. This multidisciplinary approach allows us to investigate how cells sense and respond to their environment, how signaling pathways regulate organ development and maintain homeostasis, and how disruptions in these processes contribute to the onset and progression of disease.
