Table 2.
Outstanding questions for cancer immunotherapy targeting neoantigens.
| 1. | How does this approach overcome the heterogeneity of tumor? |
| 2. | Does the number of neoantigens correlate with the mutation rate in each tumor specimen? |
| 3. | Can this approach apply to a variety types of cancers, especially cancers with low mutation rate? |
| 4. | Can neoantigens induce tolerance? Can Treg specifically recognize neoantigens and induce tolerance? |
| 5. | Are the number and fitness of neoantigen-specific T cells important for the efficacy of cancer immunotherapy? |
