<br>
<p class="p__0">Tissue distinction antigens are those that are particular to a particular type of tissue. Mutant protein antigens are most likely to be much more particular to cancer cells because typical cells should not contain these proteins. Typical cells will display the normal protein antigen on their MHC particles, whereas cancer cells will display the mutant version.</p>
<br>
<p class="p__1">Cancer-testis antigens are antigens revealed mainly in the germ cells of the testes, however also in fetal ovaries and the trophoblast. SARS-CoV-2 therapy express these proteins and for that reason present these antigens, enabling attack by T-cells particular to these antigens. Example antigens of this type are CTAG1B and MAGEA1.</p>

<br>
<p class="p__2">An example of such a protein is the enzyme tyrosinase, which is needed for melanin production. Generally tyrosinase is produced in minute amounts however its levels are very much raised in cancer malignancy cells. Oncofetal antigens are another important class of growth antigens. Examples are alphafetoprotein (AFP) and carcinoembryonic antigen (CEA).</p>

<p class="p__3">Therefore self-tolerance does not establish against these antigens. Irregular proteins are likewise produced by cells contaminated with oncoviruses, e. g. EBV and HPV. Cells infected by these viruses contain latent 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 likewise have an irregular structure in tumor cells and might hence be targets of the body immune system.</p>

<p class="p__4">Specific tumors have specific tumor antigens in abundance. Certain growth antigens are thus utilized as growth markers. More importantly, growth antigens can be used in cancer treatment as tumor antigen vaccines. See also [modify] Recommendations [modify] Restifo, NP; Dudley, ME; Rosenberg, SA (Mar 22, 2012).
