AT-3 Mouse Mammary Carcinoma Cell Line AT-3 mouse mammary tumor cell line may be used to develop mouse models for mammary cancer studies.

Tumor-induced immunosuppression is a common phenomenon in cancer and an important consideration for cancer immunotherapy. However, most studies on tumor-induced immunosuppression rely on tumor implant models, in which the disease progresses rapidly and usually causes non-physiological host responses that do not recapitulate normal tumor development and progression . Models that generate autochthonous tumors are therefore valuable for providing more physiologically-relevant systems for investigating tumor-host interactions and longer-term immunosuppressive effects.
