DCs had been identified by their CDc and MHCII double positivity. In contrast to lymphocytes, the number of DCs didn’t change inside the directly irradiated animals. Bystander responses had been also absent for all doses (Figure A). TLR expression on DC cell surface is a sign of DC activation by lipopolysaccharide (LPS) or LPSlike endogenous danger signals, like higher mobility group binding protein (HMGB) . Due to the fact radiationinduced cellular harm is associated with danger signal release, we investigated radiationinduced changes in the fraction of TLRexpressing DCs.
