The Of About: Tumor antigen - DBpedia

Antigenic compound produced in tumor cells The spectrum of target antigens connected with tumor immunity and allo-immunity after allogeneic hematopoietic stem cell transplant. Host-derived T and B cells can be induced to acknowledge tumor-associated antigens, whereas donor-derived B and T cells can acknowledge both tumor-associated antigens and alloantigens. Growth antigen is an antigenic substance produced in growth cells, i.

Tumor Antigens and Their Role in Immune Response in Melanoma

Tumor antigens are beneficial tumor markers in recognizing growth cells with diagnostic tests and are potential candidates for usage in cancer treatment. The field of cancer immunology research studies such topics. Mechanism of growth antigenesis [modify] Processing of growth antigens acknowledged by CD8+ T cells Typical proteins in the body are not antigenic due to the fact that of self-tolerance, a procedure in which self-reacting cytotoxic T lymphocytes (CTLs) and autoantibody- producing B lymphocytes are culled "centrally" in primary lymphatic tissue (BM) and "peripherally" in secondary lymphatic tissue (primarily thymus for T-cells and spleen/ lymph nodes for B cells).

This might consist of typical proteins that are well sequestered from the body immune system, proteins that are generally produced in extremely small quantities, proteins that are normally produced only in specific stages of advancement, or proteins whose structure is modified due to mutation. Classification of tumor antigens [edit] Classes of human growth antigens acknowledged by T lymphocytes, with their genetic process At first growth antigens were broadly classified into 2 classifications based upon their pattern of expression: Tumor-Specific Antigens (TSA), which are present just on tumor cells and not on any other cell and Tumor-Associated Antigens (TAA), which are present on some growth cells and likewise some normal cells.

The modern-day classification of growth antigens is based on their molecular structure and source. Accordingly, they can be classified as; [] Products of Mutated Oncogenes and Growth Suppressor Genes Products of Other Mutated Genes Overexpressed or Aberrantly Expressed Cellular Proteins Growth Antigens Produced by Oncogenic Viruses Oncofetal Antigens Modified Cell Surface Glycolipids and Glycoproteins Cell Type-Specific Distinction Antigens Any protein produced in a tumor cell that has an abnormal structure due to mutation can serve as a  tumor antigen .
