Abstract
Current tumor neoantigen calling algorithms primarily rely on epitope/major histocompatibility complex (MHC) binding affinity predictions to rank and select for potential epitope targets. These algorithms do not predict for epitope immunogenicity using approaches modeled from tumor-specific antigen data. Here, we describe peptide-intrinsic b...... hiện toàn bộ
Immunotherapy Converts Nonimmunogenic Pancreatic Tumors into Immunogenic Foci of Immune RegulationCancer Immunology Research - Tập 2 Số 7 - Trang 616-631 - 2014

AbstractPancreatic ductal adenocarcinoma (PDAC) is considered a “nonimmunogenic” neoplasm. Single-agent immunotherapies have failed to demonstrate significant clinical activity in PDAC and other “nonimmunogenic” tumors, in part due to a complex tumor microenvironment (TME) that provides a formidable barrier to immune infiltration and function. We designed a neoadju...... hiện toàn bộ
Induction of T-cell Immunity Overcomes Complete Resistance to PD-1 and CTLA-4 Blockade and Improves Survival in Pancreatic CarcinomaCancer Immunology Research - Tập 3 Số 4 - Trang 399-411 - 2015

Abstract
Disabling the function of immune checkpoint molecules can unlock T-cell immunity against cancer, yet despite remarkable clinical success with monoclonal antibodies (mAb) that block PD-1 or CTLA-4, resistance remains common and essentially unexplained. To date, pancreatic carcinoma is fully refractory to these antibodies. Here, using a geneti...... hiện toàn bộ
Mechanisms by Which Dendritic Cells Present Tumor Microparticle Antigens to CD8+ T CellsCancer Immunology Research - Tập 6 Số 9 - Trang 1057-1068 - 2018

Abstract
Tumor cell–derived microparticles (T-MP) contain tumor antigen profiles as well as innate signals, endowing them with vaccine potential; however, the precise mechanism by which DCs present T-MP antigens to T cells remains unclear. Here, we show that T-MPs activate a lysosomal pathway that is required for DCs presenting tumor antigens of T-MP...... hiện toàn bộ
Phage-Based Anti-HER2 Vaccination Can Circumvent Immune Tolerance against Breast CancerCancer Immunology Research - Tập 6 Số 12 - Trang 1486-1498 - 2018

Abstract
Δ16HER2 is a splice variant of HER2 and defined as the transforming isoform in HER2-positive breast cancer. It has been shown that Δ16HER2 promotes breast cancer aggressiveness and drug resistance. In the present work, we used in silico modeling to identify structural differences between Δ16HER2 and the wild-type HER2 proteins. We then devel...... hiện toàn bộ
Mast Cells: Potential Positive and Negative Roles in Tumor BiologyCancer Immunology Research - Tập 1 Số 5 - Trang 269-279 - 2013
Thomas Marichal, Mindy Tsai, Stephen J. Galli
Abstract
Mast cells are immune cells that reside in virtually all vascularized tissues. Upon activation by diverse mechanisms, mast cells can secrete a broad array of biologically active products that either are stored in the cytoplasmic granules of the cells (e.g., histamine, heparin, various proteases) or are produced de novo upon cell stimulation ...... hiện toàn bộ
NF-κB, an Active Player in Human CancersCancer Immunology Research - Tập 2 Số 9 - Trang 823-830 - 2014
Yifeng Xia, Shen Shen, Inder M. Verma
Abstract
NF-κB comprises a family of five transcription factors that form distinct protein complexes, which bind to consensus DNA sequences at promoter regions of responsive genes regulating cellular processes. The past three decades have witnessed remarkable progress in understanding the NF-κB signaling pathway in physiologic and pathologic conditio...... hiện toàn bộ
Immunologic Recognition of a Shared p53 Mutated Neoantigen in a Patient with Metastatic Colorectal CancerCancer Immunology Research - Tập 7 Số 4 - Trang 534-543 - 2019

Abstract
Adoptive cell therapy (ACT) with T cells targeting neoantigens can mediate durable responses in patients with metastatic cancer. Cell therapies targeting common shared antigens for epithelial cancers are not yet broadly available. Here, we report the identification and characterization in one patient of T-cell receptors (TCRs) recognizing mu...... hiện toàn bộ
Possible Interaction of Anti–PD-1 Therapy with the Effects of Radiosurgery on Brain MetastasesCancer Immunology Research - Tập 4 Số 6 - Trang 481-487 - 2016

Abstract
Delayed radiation-induced vasculitic leukoencephalopathy related to stereotactic radiosurgery (SRS) of brain metastases has been reported to manifest clinically 9 to 18 months after treatment. Immune-modulating therapies have been introduced to treatment regimens for malignancies with metastatic predilection to the brain. The interaction of ...... hiện toàn bộ
