• The role of the immune system in tumor progression has been the subject of research for more than 100 years since Paul Ehrlich hypothesized that the presence of the immune system limits the occurrence of cancer. One of the mechanisms hindering the initiation and progression of the tumor is the cytotoxic activity of macrophages; however, in some cases, it is not sufficient to control tumorigenesis. This may be due to both the development of resistance of tumor cells to the antitumor activity of macrophages and the development of a tolerant phenotype of macrophages that do not have sufficient antitumor activity. In this work, the lung cancer cells resistant to the cytotoxic action of macrophages were obtained and characterized for the first time, and the genes associated with the observed changes were identified. Understanding the mechanisms of resistance of tumor cells to the cytotoxic activity of macrophages and the peculiarities of its manifestation in a tumor environment is critically important for improving the effectiveness of the existing methods of cancer treatment and developing novel methods for tumor immunotherapy.
