1 Moreover, we found that Pb-increased quiescence of HSC critically relied on a synergetic action of Pb and IFNgamma on BM-resident macrophages (MΦ), but not a direct action of Pb on HSC. Lead interferon gamma Homo sapiens
2 Specifically, in steady state, BM-MΦ promoted HSC proliferation; and upon Pb treatment, IFNgamma was induced in the BM, and thereafter Pb in synergism with IFNgamma acted on BM-MΦ to cause BM-MΦ to become suppressive for HSC proliferation, thus leading to increased quiescence of HSC. Lead interferon gamma Homo sapiens
3 Specifically, in steady state, BM-MΦ promoted HSC proliferation; and upon Pb treatment, IFNgamma was induced in the BM, and thereafter Pb in synergism with IFNgamma acted on BM-MΦ to cause BM-MΦ to become suppressive for HSC proliferation, thus leading to increased quiescence of HSC. Lead interferon gamma Homo sapiens
4 Specifically, in steady state, BM-MΦ promoted HSC proliferation; and upon Pb treatment, IFNgamma was induced in the BM, and thereafter Pb in synergism with IFNgamma acted on BM-MΦ to cause BM-MΦ to become suppressive for HSC proliferation, thus leading to increased quiescence of HSC. Lead interferon gamma Homo sapiens
5 Our study suggests that Pb increased the quiescence of HSC via a synergetic action of Pb and IFNgamma on BM-MΦ, which was a previously unrecognized toxicity of Pb. Lead interferon gamma Homo sapiens
