Impact of Radiation on Immunity
Preliminary data in our lab have shown a long-lasting impact of neonatal irradiation on the CD4 T cell response against influenza viruses. Although defective CD4 T cells response did not compromise immunity to influenza viruses, it is possible that CD4 T cell-mediated protection against other extracellular pulmonary pathogens can be compromised by exposure to radiation in neonatal life (Radiat Res 184(4): 352-366: 2015). Thus, we are currently focused to investigate the effect of neonatal irradiation in the control of clinically relevant pulmonary pathogens.
