Our cells are constantly communicating, and scientists have developed an efficient way to find out what messages they are sending in protein-packed biological suitcases called exosomes. These spherical exosomes, which reside in the internal membrane of a cell but will eventually head out to get inside another cell, transport large molecules like proteins, a basic building block in the body and drivers of biological activity, and RNA, which produces protein. “This is an ongoing process,” says Dr. Sang-Ho Kwon, Cell Biologist in the Department of Cellular Biology and Anatomy at the Medical College of Georgia at Augusta University, and there is increasing evidence that it occurs both in states of health and disease. “We are trying to figure out this puzzle of what exosomes are doing in different scenarios,” says Dr. Kwon. He is corresponding author of a study in the Journal of Extracellular Vesicles detailing a labeling technique he and his research team have developed to analyze the contents of exosomes from any specific cell type to better understand their role in wellbeing and illness.
