    • Methods for enhancing the therapeutic and adjuvant use of IL-12 by reducing unwanted transient immunosuppression caused by IL-12 or by high doses thereof involve co-administering IL-12 with an effective amount of an agent that inhibits or neutralizes nitric oxide (NO) in vivo. Enhanced vaccine therapy involves co-administering the IL-12 adjuvant, a selected vaccine antigen and the NO inhibiting/neutralizing agent. Additionally, the toxicity of IL-12 treatment may be reduced by co-administering IL-12 with an effective amount of the NO inhibiting or neutralizing agent. A therapeutic composition characterized by reduced toxicity in mammals contains IL-12, preferably a low dose thereof, and an NO inhibiting or neutralizing agent in a pharmaceutically acceptable carrier. A vaccine composition contains an effective adjuvanting amount of IL-12, an effective amount of an NO inhibiting or neutralizing agent, and an effective protective amount of a vaccine antigen in a pharmaceutically acceptable carrier.
    • 通过减少由IL-12引起的不需要的瞬时免疫抑制或通过高剂量来增强IL-12的治疗和辅助使用的方法包括将IL-12与有效量的抑制或中和一氧化氮(NO) 体内。 增强的疫苗疗法包括共同施用IL-12佐剂,选择的疫苗抗原和NO抑制/中和剂。 另外,通过与有效量的NO抑制剂或中和剂共同施用IL-12可以降低IL-12治疗的毒性。 特征在于哺乳动物毒性降低的治疗组合物含有药物可接受载体中的IL-12,优选低剂量的NO抑制剂或中和剂。 疫苗组合物在药学上可接受的载体中含有有效佐剂量的IL-12,有效量的NO抑制剂或中和剂和有效保护量的疫苗抗原。
