Padua Research Archive, l’archivio istituzionale della produzione scientifica dell’Università degli Studi di Padova, ha lo scopo di raccogliere, documentare, conservare e pubblicare, anche ad accesso aperto, i prodotti della ricerca dell’Ateneo. Padua Research Archive utilizza la piattaforma IRIS (Institutional Research Information System) sviluppata da Cineca.
EnglishWe report the occurrence of chromosome instability in human T lymphocytes irradiated in vitro with gamma-rays and cultured for several generations before analysis. The delayed effects of gamma-radiation have been evaluated by conventional and molecular (chromosome painting) cytogenetics in preparations obtained from long-term bulk cultures or clonal cultures. The results indicate that the cell progeny of gamma irradiated human T lymphocytes can be characterized by a higher rate of chromosome damage, but this effect depends on the individual donor response to ionizing radiation. Evidence has been collected about a differential involvement of chromosomes 7, 9 and 19 in the induced chromosome rearrangements, and this effect is equally visible as an immediate or delayed response of human T lymphocytes to ionizing radiation.
