Q: Question: Does low-dose radiotherapy selectively reduce adhesion of peripheral blood mononuclear cells to endothelium in vitro?
Answer: The anti-inflammatory effect of LD-RT might, in part, be due to the reduction in the adhesion of PBMC to EC. This reduction in adhesion might be a consequence of the reduced expression of L-selectin on the surface of PBMC, and the inhibition of adherence by soluble L-selectin shed by PBMC in vitro.
A:
yes
