The technological advances occurred in the last few years have led to a great increase in the number of tumor associated antigens TAA that are currently available for clinical applications.

In this review we provide a comprehensive list of human tumor antigens as reported in the literature updated at February The list includes all T cell-defined epitopes, while excluding analogs or artificially modified epitopes, as well as virus-encoded and antibodies-recognized antigens. TAAs are listed in alphabetical order along with the epitope sequence and the HLA allele which restricts recognition by T cells. Data on the tissue distribution of each antigen are also provided together with an extensive bibliography that allows a rapid search for any additional information may be needed on each single antigen or epitope.

Overall, the updated list is a database tool for clinicians, scientists and students who have an interest in the field of tumor immunology and immunotherapy.

DNGR-1 CLEC9A is an internalizing receptor with high expression narrowly restricted to cDC1s in mouse and humans, although it shows low expression on other cell types [ 84 , 85 , , ].

Its main function may be the routing of necrotic cell-derived material into nonlysosomal compartments for cross-presentation [ 55 , , ]. Since cDC1s selectively express the chemokine receptor XCR1, targeting of this receptor with a construct of its ligand XCL1 coupled with antigen was also effective in inducing CD4 and CD8 T-cell-mediated responses against viral infection [ ]. A caveat for the formulation of antigens targeted to DC receptors is that the nature of the most immunogenic tumor antigens is usually ignored.

Indeed, the most powerful tumor antigens are the result of unique non-synonymous mutations in their translated genes whose peptide sequences fit the autologous MHC-I and MHC-II alleles acting as antigen-presenting molecules. Such antigens specific to each tumor are named neoantigens. The use of cancer neoantigens for vaccination holds much promise for the delivery of efficacious immunotherapy strategies [ ], particularly when combined with checkpoint inhibitors [ ]. Targeting neoantigens to cross-priming DCs seems to be a reasonable strategy, but preparing individual DC-targeting moieties for each patient is a daunting biotechnical challenge.

This approach, using neoantigens and shared tumor antigens, is currently being tested in clinical trials against melanoma and breast cancer NCT, NCT Alternatively, naked synthetic mRNA encoding cancer neoantigens can be injected inside LNs with ultrasound guidance achieving powerful vaccine effects [ ]. We will briefly discuss the involvement of cross-priming in currently used therapeutic strategies and the potential for improvement of both cytotoxic therapy and immunotherapy upon combination with cross-priming enhancers.

Chemotherapy can improve immunotherapeutic approaches in two main ways: first, by inducing ICD of tumor cells, allowing for antitumor T-cell cross-priming by native DCs; second, by modulating the phenotype of tumor-associated regulatory populations such as regulatory T cells Tregs , TAMs or myeloid-derived suppressor cells. It is now well known that not all chemotherapeutic agents induce ICD [ ]: anthracyclines such as doxorubicin or mitoxantrone [ , ] and cyclophosphamide [ ] are strong inducers of ICD and tumor antigen cross-presentation, while cisplatin is not [ ].

This suggests a more complex interplay of immune cells involved in the response to chemotherapy. The proimmune effects of chemotherapy may need lower doses than the maximally tolerable dose levels used as a standard [ ]. All in all, the line of work pioneered by Guido Kroemer and Laurence Zitvogel puzzled the world of clinical oncology, since in mouse models some forms of chemotherapy act against tumors with an absolute need for cellular immune responses dependent on ICD [ ].

Ionizing radiation is an ICD inducer, and therefore a good candidate for successful combination with immunotherapy [ , , ]. Radiotherapy RT has been shown to potentiate tumor antigen cross-presentation in mouse models [ ]. Several groups explored the intratumoral injection of DCs into irradiated mouse tumor models with positive results [ , ].

These findings are consistent with the requirement for DC-mediated cross-priming in mouse models in which RT induces abscopal effects to concomitant non-irradiated tumors, that can be greatly potentiated with immunomodulatory anti-PD-1, anti-CTLA-4 and anti-CD mAbs [ — ]. It should be kept in mind that TIDCs under the irradiation beam also undergo functional changes [ ]. Curiously, a conversion from pro- to anti-tumor myeloid populations occurs in the TME of tumors irradiated at low doses [ ].

Active combinations of RT and local TLR agonists have been preclinically reported [ ] and clinically tested against follicular lymphoma [ ] and breast cancer [ ]. Accordingly, if anti-CD47 mAb disrupts this inhibitory interaction, more phagocytosis takes place. Not surprisingly, local immunotherapy based on STING agonist cyclic dinucleotides given intratumorally absolutely requires STING expression in Batf3-dependent DCs [ ] and this function is required to enhance the therapeutic results of immune checkpoint blockade in the B16 melanoma mouse model [ ].

Moreover, Batf3-dependent DCs are critical for the antitumor activity of anti-CD agonist immunostimulatory mAbs [ 13 ].

These results suggest that the numbers of such DCs mediating cross-priming and their activation status can be modulated to enhance other immunotherapy interventions. Direct presentation by malignant cells of tumor antigen to T cells is crucial at the effector killing phase, but inefficient to prime and sustain the cytotoxic immune response [ ].

Cytotoxic T lymphocytes need therefore to recognize their cognate antigen on professional antigen-presenting cells.

Tumor-Reactive T-Cells for Adoptive Immunotherapy

Only a few years ago, cross-priming was a black box in terms of our mechanistic knowledge [ ]. The molecular and cellular details on how, where and under which circumstances cross-presentation of tumor antigens efficiently takes place are crucial for understanding immune responses against tumors and will certainly provide multiple opportunities for progress in cancer immunotherapy.
