Quantification of thioguanine-resistant lymphocytes from mice irradiated in vivo.
Adult mice were Co-60 gamma irradiated, and 7 months later splenocytes were isolated, cultured in microwells, and the frequency of hprt-deficient mutants was determined by measuring the cloning efficiency in media with 6-thioguanine. The mutant frequency at 2, 4, and 6 Gy was 1.6 x 10(-5), 4.4 x 10(-5), and 12.7 x 10(-5), respectively. The frequency of spontaneous mutants was 2.5 x 10(-6). The ...
متن کاملT lymphocytes from mice immunized with irradiated sporozoites eliminate malaria from hepatocytes.
When mice are immunized with radiation-attenuated sporozoites they are solidly protected against sporozoite challenge by an immune response that has been shown to require CD8+ lymphocytes in several strains of mice. The target of this CD8+ T-cell-dependent immunity has not been established. Immune BALB/c mice were shown to develop malaria-specific, CD8+ T-cell-dependent inflammatory infiltrates...
متن کاملImmunogenicity of Gamma-Irradiated Toxoplasma gondii Tachyzoites in Mice
The Immunogenicity of γ-irradiated tachyzoites of a highly virulent strain of Toxoplasma gondii (RH strain) was investigated. Immunized mice survived challenge infection and displayed increased interferon gamma (INF-γ ) production. On the other hand, nonimmunized controls died after 10 days and displayed a significantly decreased lymphoproliferative response to Concanavalin A (Con A). No tachyz...
متن کاملDevelopment of methemoglobin-based biological dosimetry in gamma–irradiated mice
Background: A new biological dosimeter based on methemoglobin level was developed in this study. Materials and Methods: Methemoglobin level in erythrocytes from mice subjected to &gamma rays from a 60Co source was detected using the methemoglobin kit. The dose range was from 0.5 to 8 Gy and the dose rate was 0.5 Gy/min. Results: The results demonstrate that methemoglobin level increases with in...
متن کاملIonizing radiation induces ferroptosis in splenic lymphocytes of mice
Backgrounds: It remains unclear whether radiation-induced haemorrhage in the spleen causes iron accumulation, and subsequently, ferroptosis in splenic lymphocytes. In this study, we investigated the occurrence of ferroptosis in splenic lymphocytes of gamma-irradiated mice. Materials and Methods: Mice were subjected to gamma radiation from a 137Cs source. Iron, Ferroportin 1, and iron regulatory...
