Abstract

Colorectal cancer is a prevalent and deadly malignancy globally, posing an important challenge due to its heterogeneity and treatment resistance. Although oral contraceptives have been shown to reduce the incidence of colorectal cancer, their impact on the anti-tumor effect of CD8⁺ T cells remains unclear. Here we show that the contraceptive Marvelon plays an important role in anti-MC38 tumor immunity. The contraceptive Marvelon significantly inhibits MC38 tumor growth in vivo. Marvelon treatment promotes IFN-γ expression in CD8⁺ tumor infiltrating lymphocytes, but shows dispensable impact on their exhausted profile. By further investigating the effects of Marvelon’s primary components, Ethinylestradiol and Desogestrel, we reveal that Ethinylestradiol enhances IFN-γ production in Type 1 Cytotoxic T (Tc1) cells and significantly inhibits the viability of MC38 tumor cells, whereas Desogestrel exhibits minimal effects. This study not only redefines the role of oral contraceptives but also provides valuable insights for the development of novel immunotherapeutic strategies.

期刊介绍： Molecular Immunology publishes original articles, reviews and commentaries on all areas of immunology, with a particular focus on description of cellular, biochemical or genetic mechanisms underlying immunological phenomena. Studies on all model organisms, from invertebrates to humans, are suitable. Examples include, but are not restricted to: Infection, autoimmunity, transplantation, immunodeficiencies, inflammation and tumor immunology Mechanisms of induction, regulation and termination of innate and adaptive immunity Intercellular communication, cooperation and regulation Intracellular mechanisms of immunity (endocytosis, protein trafficking, pathogen recognition, antigen presentation, etc) Mechanisms of action of the cells and molecules of the immune system Structural analysis Development of the immune system Comparative immunology and evolution of the immune system "Omics" studies and bioinformatics Vaccines, biotechnology and therapeutic manipulation of the immune system (therapeutic antibodies, cytokines, cellular therapies, etc) Technical developments.
