IL-9 is a T cell-derived cytokine that, similar to the Th2 cytokines IL-4 and IL-10, has been implicated in the response to parasitic infections, allergy, and inflammatory processes. Because both IL-4 and IL-10 can confer protection to mice from septic shock, we investigated whether IL-9 may also be capable of conferring resistance on recipients of an(More)
Highly immunogenic sublines of L1210 and LSTRA lymphomas were obtained from athymic (nude) mice treated with 4(5)-(3,3-dimethyl-1-triazeno)imidazole-5(4)carboxamide (DIC) in vivo. Conventional mice, compatible with the parent tumor, rejected the DIC-treated sublines and were relatively resistant to a subsequent challenge with the parent lines. The(More)
To determine the effect of interleukin 4 (IL-4) administration in a live sepsis model characterised by high-level production of tumour necrosis factor a (TNF-alpha), mice infected systemically with lethal or sublethal inocula of Pseudomonas aeruginosa were given the recombinant cytokine at different times before infection. Improved survival and decreased(More)
The nude mouse model (NMM) has been proposed for testing chemosensitivity of human cancer cells with encouraging results. However, nude mice cannot be considered as unreactive "test tube" recipients of allogeneic or xenogeneic tissues, since a variety of immunological functions are fully represented in these hosts. In general, graft resistance against(More)
To investigate the effect of cyclooxygenase inhibition in experimental Gram-negative sepsis, indomethacin was administered to mice at different times (1 or 5 days, or 1 h) before sublethal infection with an intravenous inoculum of Pseudomonas aeruginosa Early indomethacin exposure did not alter the outcome of infection, yet treatment at the time of(More)
Excessive production of proinflammatory cytokines, including TNF-alpha, IL-1, IL-6, IL-12, and IFN-gamma is thought to contribute significantly to lethality in septic shock syndromes. IL-23 is a heterodimeric cytokine that combines the p40 subunit of IL-12 with a specific p19 subunit. Similar to IL-12, IL-23 is considered to be a key immunoregulator in the(More)
Several murine tumors were used to determine whether the phenomenon of tumor inhibition in athymic "nude" mice reported previously could be extended to other tumor systems in nude as well as conventional mice. The results with the L5MF-22 tumor line were confirmed, and similar data were obtained with the K36 leukemia of AKR mice and the LAF-17 leukemia of(More)
The effects of indomethacin administration on Pseudomonas aeruginosa infection were investigated in neutropenic mice. Cyclophosphamide-treated mice received the drug at 2.5 to 12 mg/kg according to different regimens, to be challenged with a lethal intraperitoneal inoculum of P. aeruginosa 5 days after myelosuppression. A single exposure of the neutropenic(More)
