EVs are composed of various kinds of proteins, lipids, and genetic materials (DNA and/or RNA). Therefore, identification of EV components is a prerequisite of understanding EV function and biogenesis mechanisms. To this end, Professor Gho’s group tries to construct databases of EV components. EVs are composed of diverse molecules and are secreted by various cell types, including immune, neural, tumor and stem cells. Therefore, it could be readily inferred that EVs might play many different functions. However, the physiological roles of EVs are generally unclear. Professor Gho’s group studies EV functions in vitro and in vivo. Such studies might help to understand various biological phenomena, including cancer, which could not be explained fully by soluble intercellular communicating molecules and intracellular communication. EVs could be classified by their biogenesis mechanism: exosome, which are formed inside the multivesicular endosomes (MVEs) of the secreting cells and released by fusion of MVEs and plasma membrane; microvesicles, which are formed by blebbing and/or shedding from the plasma membrane. However, factors which promote or inhibit EV biogenesis are largely unknown. Professor Gho’s group tries to elucidate EV biogenesis mechanisms and modulate EV biogenesis. Together with studies of EV functions, elucidation of EV biogenesis mechanisms might help to develop novel diagnostics and identify novel targets involved in the pathogenesis of various diseases. The systemic studies on EVs are critical for understanding the intercellular communication network that is essential for decoding the secrets of life and elucidating the exact causes of many diseases.
