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)
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)
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)
