In Vitro Induction of Tumor-specific Immunity
Induction of tumor-specific immunity in vitro was accomplished by cocultivation of cortisone-resistant murine thymocytes or spleen cells with irradiated syngeneic plasma cell tumors (PCT). The cytotoxic activity generated could be detected in a short-term (51)Cr-release assay. Optimal cytotoxic activity against PCT-associated transplantation antigens (TATA) was generated after 7 days in culture...
متن کاملBoosting Tumor-Specific Immunity Using PDT
Photodynamic therapy (PDT) is a cancer treatment with a long-standing history. It employs the application of nontoxic components, namely a light-sensitive photosensitizer and visible light, to generate reactive oxygen species (ROS). These ROS lead to tumor cell destruction, which is accompanied by the induction of an acute inflammatory response. This inflammatory process sends a danger signal t...
متن کاملRadiotherapy supports protective tumor-specific immunity
Radiotherapy is an important therapeutic option for the treatment of cancer. Growing evidence indicates that, besides inducing an irreversible DNA damage, radiotherapy promotes tumor-specific immune response, which significantly contribute to therapeutic efficacy. We postulate that radiotherapy activates tumor-associated dendritic cells, thus changing the tolerogenic tumor environment into an i...
متن کاملLoss of tumor-specific and idiotype-specific immunity with age
The ultraviolet light-induced fibrosarcoma 1591 undergoes "first-set rejection" when transplanted into normal syngeneic mice. We found, however, that the primary resistance of normal mice decreases with age, beginning at 9--12 mo, equivalent to middle age for mice. Mice lose with age the capacity to mount both idiotypic and anti-idiotypic responses responsible for controlling the growth of tumo...
متن کاملPolyomavirus-Specific Cellular Immunity: From BK-Virus-Specific Cellular Immunity to BK-Virus-Associated Nephropathy?
In renal transplantation, BK-virus (BKV)-associated nephropathy has emerged as a major complication, with a prevalence of 1-10% and graft loss in >50% of cases. BKV is a member of the polyomavirus family and rarely induces apparent clinical disease in the general population. However, replication of polyomaviruses, associated with significant organ disease, is observed in patients with acquired ...
