Experimental study of the efficacy of combined use of cancer vaccine and interferon

Aim: To study in in vivo model the efficacy of combined scheme of administration of cancer vaccine (CV) and interferon (IFN). Materials and Methods: Lewis lung carcinoma (LLC) was transplanted to male C57Bl mice. For treatment, CV prepared from LLC cells with the use of cytotoxic lectins of B. subti...

Original contributions Aim: To study in in vivo model the efficacy of combined scheme of administration of cancer vaccine (CV) and interferon (IFN). Materials and Methods: Lewis lung carcinoma (LLC) was transplanted to male C57Bl mice. For treatment, CV prepared from LLC cells with the use of cytotoxic lectins of B. subtilis B-7025, and preparation of murine IFN-alpha were used. Therapeutic effect was evaluated by measurement of tumor volume and analysis of average life span (ALS) of treated animals. Immunologic study included determination of antitumor cytotoxicity of T-lymphocytes (CTL) and natural killer (NK) cells by radiometric method, functional activity of peritoneal macrophages (MP) — by colorimetric test with nitroazole blue, and evaluation of titers of tumor necrosis factor (TNF) and interleukins-1 and -2 (IL-1, 2). Results: It has been shown that the use of IFN preparation significantly elevated efficacy of vaccine therapy of solid form of LLC: duration of latent period of tumor growth elevated by 25%, ALS — by 28%, index of tumor growth inhibition — by 35–40%. Upon combined use of CV and IFN, significant activation of the cells — effectors of nonspecific immune defense (MP), and specific one (CTL) was observed. Conclusion: The obtained results evidence on perspectiveness of the development of combined schemes of administration of CV and IFN for elevation of the efficacy of vaccine therapy. Цель: исследовать в эксперименте эффективность комбинированной схемы введения противоопухолевой вакцины (ПВ) и интерферона (ИФН). Материалы и методы: карциному легкого Льюис (КЛЛ) трансплантировали мышам-самцам C57Bl. Для лечения использовали ПВ, приготовленную из клеток КЛЛ с помощью цитотоксических лектинов B. subtilis B-7025, и препарат мышиного ИФН. Терапевтический эффект оценивали путем измерения объема солидной опухоли и анализа средней продолжительности жизни опытных животных. Иммунологическое исследование включало определение противоопухолевой цитотоксичности Т-лимфоцитов (ЦТЛ) и природных киллерных клеток (ПКК) радиометрическим методом; функциональной активности перитонеальных макрофагов (Мф) в колориметрическом НСТ-тесте; определение титров фактора некроза опухоли (ФНО), интерлейкинов-1 и -2. Результаты: показано, что использование препарата ИФН существенно повышает эффективность вакцинотерапии солидной формы модельной КЛЛ: на 25% повышается продолжительность латентного периода, на 28% — средняя продолжительность жизни мышей, на 35–40% — индекс торможения опухолевого роста. При комбинированном применении ПВ и ИФН отмечают существенную активацию клеток-эффекторов как неспецифической (Мф), так и специфической (ЦТЛ) иммунной защиты. Выводы: полученные результаты свидетельствуют о перспективности разработки комбинированных схем введения ПВ с ИФН, позволяющих повысить эффективность вакцинотерапии. 2007 Article Experimental study of the efficacy of combined use of cancer vaccine and interferon / G.P.
