Megjegyzések:	On a roundtrip to Mars, astronauts are expectedly exposed to an approximate amountof radiation that exceeds the lifetime limits on Earth. This elevated radiation dose ismainly due to Galactic Cosmic Rays and Solar Particle Events. Specific patterns of theN-glycosylation of human Igs have already been associated with various ailments such asautoimmune diseases, malignant transformation, chronic inflammation, and ageing. Thefocus of our work was to investigate the effect of low-energy proton irradiation on the IgGN-glycosylation profile with the goal if disease associated changes could be detected duringspace travel and not altered by space radiation. Two ionization sources were used duringthe experiments, a Van de Graaff generator for the irradiation of solidified hIgG samples invacuum, and a Tandetron accelerator to irradiate hIgG samples in aqueous solution form.Structural carbohydrate analysis was accomplished by CE with laser induced fluorescentdetection to determine the effects of simulated space radiation onN-glycosylation of hIgG1samples. Our results revealed that even several thousand times higher radiation doses thatof astronauts can suffer during long duration missions beyond the shielding environmentof Low Earth Orbit, no changes were observed in hIgG1N-glycosylation. Consequently,changes inN-linked carbohydrate profile of IgG1 can be used as molecular diagnostic toolsin space.
