Background: Awareness of age-related features of carcinogenesis and the importance of cellular immunity is crucial for developing effective antitumor therapies for specific patient groups.
Methods: In this study, we examined different populations of cancer stem cells (CSCs) and circulating tumor cells (CTCs) in "young" (8-10 weeks) and "aged" (80-82 weeks) C57BL/6 male mice. We used an orthotopic model of Lewis lung carcinoma (LLC) to evaluate the effectiveness of cell therapy targeting lung cancer through reprogrammed CD8-positive T cells (rCD8+ T cells) in mice from two different ages.
Background: Metastatic disease is a major and difficult-to-treat complication of lung cancer. Considering insufficient effectiveness of existing therapies and taking into account the current problem of lung cancer chemoresistance, it is necessary to continue the development of new treatments.
Methods: Previously, we have demonstrated the antitumor effects of reprogrammed CD8 T-cells (rCD8 T-cells) from the spleen in mice with orthotopic lung carcinoma.
