Interferon-gamma(-/-) (IFN-gamma(-/-)) and IFN-gamma(+/+) C57BL/6 mice (3 weeks of age) completed the production of morphogenesis-derived hair. Around 6 weeks of age, however, most of the IFN-gamma(-/-) but none of the IFN-gamma(+/+) mice began to lose hairs in the dorsal and occipital areas in the absence of inflammatory reactions, and the alopecia was(More)
Hair growth abnormalities in mice usually are accompanied by histologic abnormalities as well. Recently, however, we reported a mouse model in which an arrest of the hair cycle and diffuse shedding of the hair without pathologic features induced alopecia in interferon-gamma(-/-) (IFN-gamma(-/-)) C57BL/6 (B6) mice. Here, we explored the cellular origin of(More)
We previously demonstrated that around 6 weeks of age most of the interferon-gamma (IFN-gamma)(-/-) but none of the IFN-gamma(+/+) C57BL/6 mice began to lose hair in their dorsal or occipital areas or both and that a single s.c. injection of IFN-gamma into IFN-gamma(-/-) mice at 3 but not at 8 weeks of age (or later) could protect all the mice from(More)
