Dr. Santosh Kumar, a professor at the University of Tennessee Health Science Center, told MNT that:
“The study shows a significant role of nasal epithelial extracellular vesicles (EVs) in the sensitivity to viral or other infections and perhaps a self-defense mechanism via TLR. In addition, the EVs’ biology via TLR may change based on the presence of seasonal infectious agents or allergens. This provides an adaptive biological role of nasal epithelial EVs. The findings may also be generalized to other EVs generated by other organs/tissues upon exposure to other agents.”
