Multi-Disciplinary Training Area
Disease Mechanisms and Therapeutics (DMT), Immunology [IMM]
Immune monitoring to discover mechanisms and biomarker of cancer immunotherapies:
Multiscale (host, circulation, tissues, single cell), multiomics (immunophenotyping, immunopathology, immunotranscriptomics, bioinformatics) approaches for biomarker discovery and understanding of mechanisms contributing to clinical responses, adverse events, or primary and acquired resistance to tumor immunotherapies.
Mechanisms of antigen presentation to T cells:
Mechanisms of antigen presentation to and recognition by T cells, including defining epitopes, evaluating viral, bacterial, and parasitic vectors, cross-presentation of antigen to HLA class I, and endogenous antigen presentation to HLA class II.
Tissue immune microenvironment:
Assessment of the tumor microenvironment for immunocytes and suppressive signals, including development of novel spatial technologies to address in depth biomarkers at the tissue site.
Impact of immunoregulation on tumor antigen-specific responses:
Impact of immunoregulation on tumor antigen-specific responses, from co-inhibitory molecules expressed on T cells at the tumor site to the effect of regulatory T cells on anti-tumor effectors, and study of immune tolerance.
Antigen-specific spontaneous and immunotherapy-induced tumor immunity:
Characterization of serological and cellular immune responses against tumor antigens such as NY-ESO-1, MAGE-A3, or p53, and for their capacity to induce immune responses both spontaneously and in the setting of cancer immunotherapy.
Inflammatory diseases:
Role of GM-CSF autoantibodies throughout Crohn's disease development. Dissecting role of cytokines, antibody and T cell responses in COVID-19 patients after infection or vaccination.
