Abstract
Adoptive transfer of human TALL-104 killer cells into a dog with metastatic mammary adenocarcinoma resulted in 50% reduction of the largest lung metastasis and stabilization of the other lesions for 10 weeks, accompanied by the development of tumor-specific immune responses. Upon halting cell therapy, the dog developed new lung lesions within 10 weeks and died of slowly progressive disease. TALL-104 cell therapy of mice bearing the dog's tumor xenograft induced 65% reduction of local tumor growth and regression of lung metastases in 100% of the animals. The overall findings indicate the therapeutic potential of TALL-104 cells for canine mammary tumors.
