Unlocking the secrets of how the body heals itself, especially when organs become diseased, a new study shows that the presence of small particles known as microvesicles helps cellular communication and enables healing.
Microvesicles are much smaller than a normal cell and contain genetic information such as messenger ribonucleic acid (RNA), other species of RNA and protein.
Jason Aliotta, physician researcher at the critical care and haematology-oncology departments at Rhode Island Hospital (RIH), and colleagues focussed on these small particles.
During times of cellular injury or stress, or with certain diseases like cancer, infections and cardiovascular disease, these particles are shed and then taken up by other cells in the body.
The genetic information and protein in the microvesicles help to reprogramme the accepting cell to behave more like the cell from which the particle was derived.
Aliotta, also an assistant professor of medicine at the Brown University, said: “What we attempted to understand is how cells within the bone marrow are able to repair organs that are unrelated to those bone marrow cells, such as the lung.
