Feiyuebio research direction includes metabolomics, signal transduction, neuroscience, and immunology. Metabolomics is the study of metabolites and their role in cellular processes like energy metabolism and biosynthesis. Signal transduction refers to the process of transmitting extracellular signals through intracellular biochemical cascades via receptors and signaling pathways. Neuroscience is the study of the nervous system, including the structure and function of the brain. Immunology charts the immune system's role in health and disease by studying the physiological and molecular characteristics of its components.
