Antitumor action of lymphokin-activated сеlls of patients with soft tissue sarcomas and melanomas in dependence on expression of MHC classes I and II antigenes
Aim: To study expression of major histocompatibility complex (MHC) classes І and ІІ antigens and CD25, CD71, Ki-67, CD54, CD56, CD11b, PCNA on lymphocytes and tumor cells and antitumor action of lymphocytes activated with IL-2. Materials and Methods: Tumor explants (soft tissue sarcoma, n = 20, mela...

Vinnichuk, U.D. Belova, O.B. Baranovich, V.V. Original contributions Aim: To study expression of major histocompatibility complex (MHC) classes І and ІІ antigens and CD25, CD71, Ki-67, CD54, CD56, CD11b, PCNA on lymphocytes and tumor cells and antitumor action of lymphocytes activated with IL-2. Materials and Methods: Tumor explants (soft tissue sarcoma, n = 20, melanoma, n = 25) were co-cultivated in diffusion chambers with autologous lymphocytes; antitumor action was evaluated by morphologic patterns of explant’s growth. Expression of CD25, CD71, Ki-67, CD54, CD56, CD11b, PCNA was evaluated by the method of indirect fluorescence using respective monoclonal antibodies. Results: The highest antitumor action of lymphocytes toward soft tissue sarcoma and melanoma cells is observed if tumor cells are expressing MHC class I antigens. In the cases of soft tissue sarcoma no correlation between the level of antitumor activity of lymphocytes and expression of CD25, CD71, Ki-67, CD54, CD56, CD11b, PCNA has been found, whilst in the case of melanoma it is associated with the high level of CD11b expression. Conclusion: There is a direct correlation between sensitivity of soft tissue sarcoma and melanoma cells to action of lymphokin-activated killer cells and the level of MHC class I antigens. Цель: изучить экспрессию антигенов І и ІІ класса главного комплекса гистосовместимости (ГКГ) на лимфоцитах и опухолевых клетках (саркомы мягких тканей и меланома кожи) и противоопухолевое действие лимфоцитов, активированных и неактивированных ИЛ-2 параллельно с экспрессией некоторых рецепторов, характеризующих протеом. Материалы и методы: культивирование эксплантатов опухоли и аутологичных лимфоцитов в диффузионных камерах с дальнейшим изучением противоопухолевого действия лимфоцитов на основании морфологических особенностей роста эксплантатов. Экспрессию антигенов CD25, CD71, Ki-67, CD54, CD56, CD11b, ядерного антигена пролиферирующих клеток (ИПО-38) определяли методом непрямой флуоресценции с помощью соответствующих моноклональных антител. Результаты: наиболее выраженное противоопухолевое действие лимфоцитов как больных саркомами мягких тканей, так и меланомой проявляется по отношению к тем опухолевым клеткам, которые экспрессируют антигены I класса ГКГ. Установлено, что значение экспрессии указанных структур для противоопухолевого действия зависит от биологических особенностей опухоли: зависимости между уровнем противоопухолевой активности и экспрессией изученных рецепторов клетками больных саркомой не выявлено. В то же время наиболее выраженное противоопухолевое действие лимфоцитов больных меланомой сочеталось с высоким уровнем экспрессии ими CD11b. Выводы: установлена прямая зависимость чувствительности опухолевых клеток к действию лимфокинактивированных клеток от уровня экспрессии антигенов ГКГ I класса на клетках как меланомы, так и сарком. 2006 Article Antitumor action of lymphokin-activated сеlls of patients with soft tissue sarcomas and melanomas in dependence on expression of MHC classes I and II antigenes / N.M.
