The Only Guide for Tumor Antigen Proteins Research Tools - Creative BioMart

Tissue differentiation antigens are those that are particular to a certain kind of tissue. Mutant protein antigens are most likely to be much more particular to cancer cells because normal cells should not include these proteins. Normal cells will display the regular protein antigen on their MHC molecules, whereas cancer cells will show the mutant version.

Cancer-testis antigens are antigens expressed mostly in the germ cells of the testes, however likewise in fetal ovaries and the trophoblast. Some cancer cells aberrantly express these proteins and therefore present these antigens, allowing attack by T-cells particular to these antigens. Example antigens of this type are CTAG1B and MAGEA1.

An example of such a protein is the enzyme tyrosinase, which is required for melanin production. Typically tyrosinase is produced in minute amounts however its levels are quite raised in cancer malignancy cells. Oncofetal antigens are another crucial class of growth antigens. Examples are alphafetoprotein (AFP) and carcinoembryonic antigen (CEA).

Hence self-tolerance does not establish against these antigens. Abnormal proteins are also produced by cells infected with oncoviruses, e. g. EBV and HPV. Cells infected by these viruses include hidden viral DNA which is transcribed and the resulting protein produces an immune action. In addition to proteins, other compounds like cell surface area glycolipids and glycoproteins might also have an unusual structure in tumor cells and might therefore be targets of the immune system.

Particular growths have particular growth antigens in abundance. Specific growth antigens are thus used as growth markers. More importantly,  tumor antigen s can be utilized in cancer therapy as tumor antigen vaccines. See likewise [edit] References [edit] Restifo, NP; Dudley, ME; Rosenberg, SA (Mar 22, 2012).
