Tumor Antigens
Many tumor cells produce antigens, which may be released in the bloodstream or remain on the cell surface. Any molecule capable of being recognized by the immune system is considered…
Tumor Immunology Pathway
Tumor immunology refers to the relationship between immune function and tumor cells, which is crucial for our understanding of the mechanisms of both tumor rejection and tumor progression. The immunological…
Transplant Immunology
