Immunogenic tumor phenotype
Betteridge’s law of headlines states that if the title poses a question, the answer is “no”. So, this review starts with the proposition that if you have a tumor, it is not immunogenic.

Witryna1 dzień temu · Another important aspect worth mentioning is the relationship between MSI and tumor mutation burden (TMB). dMMR leads to a hypermutator phenotype and increased TMB, which is believed to make tumors more immunogenic. Considering all solid tumors, the simultaneous presence of MSI and TMB is quite rare and occurs … WitrynaNon-immunogenic and high-NAG tumors (blue) vs. non-immunogenic and low-NAG patient tumors (red) show HR = 0.309, p = 7.9 × 10 −5. High NAG patients with and without neoantigens were contrasted based on the relative abundance of immune cell types estimated by the TIMER algorithm ( C ), and the RNA expression of cytotoxic T …
