Antigenome defines a selection of mutated tumor peptides driving tumor-specific T-cell response
Hadlová, Petra ; Drbal, Karel (advisor) ; Dibus, Michal (referee)
T cells, as an essential part of the adaptive immune system, play crucial role in eradication of tumor growth. T cells target, interact with and eventually annihilate the tumor cells in antigen- specific (Ag) manner. T cells interact with tumor cells via short epitopes bound to the major histocompatibility complex (MHC) molecules on the tumor cell surface. Tumor specific neoepitopes arise from random somatic mutations and constitute a part of the tumor antigenome. Antigenome comprises of two classes of antigens, tumor specific antigens (TSA) and tumor associated antigens (TAA). TSA are neoantigens carrying neoepitopes unique to each tumor. TAA are self-antigens presented by both tumor cells and non-transformed cells. Each tumor cell is able to develop numerous ways to evade the immune system consisting of T cells, NK cells, macrophages and other mechanisms employed. Despite that immunotherapy has shown a great potential in personalized medicine. The stratification of responsive patients is essential for effective and durable management of therapy in clinical practice. Methods are employed, which study existing reactive T cell clones, somatic mutations present in each patient, role of somatic mutations in tumor development and present neoepitopes. All these patient- specific features facilitate...
