The Devreotes Laboratory is engaged in genetic analysis of chemotaxis in eukaryotic cells. Our ...long-term goal is a complete description of the network controlling chemotactic behavior. We are analyzing combinations of deficiencies to understand interactions among network components and carrying out additional genetic screens to identify new pathways involved in chemotaxis. A comprehensive understanding of this fascinating process should lead to control of pathological conditions such as inflammation and cancer metastasis. view more

The Artemov lab is within the Division of Cancer Imaging Research in the Department of Radiolog...y and Radiological Science. The lab focuses on 1) Use of advanced dynamic contrast enhanced-MRI and activated dual-contrast MRI to perform image-guided combination therapy of triple negative breast cancer and to assess therapeutic response. 2) Development of noninvasive MR markers of cell viability based on a dual-contrast technique that enables simultaneous tracking and monitoring of viability of transplanted stems cells in vivo. 3) Development of Tc-99m and Ga-68 angiogenic SPECT/PET tracers to image expression of VEGF receptors that are involved in tumor angiogenesis and can be important therapeutic targets. 4) Development of the concept of “click therapy” that combines advantages of multi-component targeting, bio-orthogonal conjugation and image guidance and preclinical validation in breast and prostate cancer models. view more

The Douglas Ball Lab conducts clinical trials and pre-clinical laboratory studies of thyroid ca...ncer. Our clinical trials, performed in collaboration with research staff in the upper aero-digestive group in the Sidney Kimmel Comprehensive Cancer Center, have included protocols for advanced radioiodine-refractory differentiated thyroid cancer and medullary thyroid cancer. Our pre-clinical research, conducted with Dr. Nelkin, Dr. Agrawal and other Kimmel Cancer Center researchers, includes pathogenesis and mechanisms of treatment resistance in medullary thyroid cancer, and pathogenesis and immune-directed therapy of anaplastic thyroid cancer. view more

The Pardoll Lab focuses on the regulation of antigen-specific T cell responses and studies appr...oaches to modify these responses for immunotherapy. Pardoll has a particular interest in cancer immunology and his lab’s studies on basic immunologic mechanisms have led to the development and design of a number of cancer vaccines and discovery of key checkpoint ligands and receptors, such as PD-L2, LAG-3 and neuritin, many of which are being targeted clinically.

Our primary pursuits are discovering and elucidating new molecules that regulate immune responses, investigating the biology of regulatory T cells, and better understanding the specific biochemical signatures that allow a patient’s T cells to selectively target cancer cells.

Barbara Slusher, M.A.S., Ph.D., leads a 20-member veteran drug discovery team of medicinal chem...ists, assay developers, pharmacologists, toxicologists and pharmacokinetic/drug metabolism experts, who identify novel drug targets arising from JHU faculty’s research and translate them into new, small molecule drug therapies.

Her team collaborates extensively with faculty at the Bloomberg~Kimmel Institute for Cancer Immunotherapy and leads the BKI immunotherapy drug discovery core, aimed at developing new immune-targeting drug therapies for laboratory and clinical testing at Johns Hopkins.

The goal of the lab's research is to identify molecular abnormalities that can improve the outc...ome of patients with pancreatic cancer and those at risk of developing this disease. Much of our work is focused on translational research evaluating markers and marker technologies that can help screen patients with an increased risk of developing pancreatic cancer.

Thus, marker efforts have been focused mostly on identifying markers of advanced precancerous neoplasia (PanINs and IPMNs) that could improve our ability to effectively screen patients at risk of developing pancreatic cancer. We lead or participate in a number of clinical research protocols involved in the screening and early detection of pancreatic neoplasia including the CAPS clinical trials. We maintain a large repository of specimens from cases and controls with and without pancreatic disease and use this repository to investigate candidate markers of pancreatic cancer for their utility to predict pancreatic cancer risk.

In addition, we have been working to identify familial pancreatic cancer susceptibility genes and identified BRCA2 as a pancreatic cancer susceptibility gene in 1996. We participate in the PACGENE consortium and the familial pancreatic cancer sequencing initiative. My lab also investigates pancreatic cancer genetics, epigenetics, molecular pathology, tumor stromal interactions and functional analysis of candidate genes and miRNAs. Dr. Goggins is the principal investigator of a phase I/II clinical trial evaluating the Parp inhibitor, olaparib along with irinotecan and cisplatin for patients with pancreatic cancer. view more

Current projects include:

The evaluation of mechanisms of immune tolerance to cancer in m...ouse models of breast and pancreatic cancer. We have characterized the HER-2/neu transgenic mouse model of spontaneous mammary tumors.
This model demonstrates immune tolerance to the HER-2/neu gene product. This model is being used to better understand the mechanisms of tolerance to tumor. In addition, this model is being used to develop vaccine strategies that can overcome this tolerance and induce immunity potent enough to prevent and treat naturally developing tumors. More recently, we are using a genetic model of pancreatic cancer developed to understand the early inflammatory changes that promote cancer development.

The identification of human tumor antigens recognized by T cells. We are using a novel functional genetic approach developed in our laboratory. Human tumor specific T cells from vaccinated patients are used to identify immune relevant antigens that are chosen based on an initial genomic screen of overexpressed gene products. Several candidate targets have been identified and the prevelence of vaccine induced immunity has been assessed .
This rapid screen to identify relevant antigenic targets will allow us to begin to dissect the mechanisms of tumor immunity induction and downregulation at the molecular level in cancer patients. More recently, we are using proteomics to identify proteins involved in pancreatic cancer development. We recently identified Annexin A2 as a molecule involved in metastases.

The analysis of antitumor immune responses in patients enrolled on vaccine studies. The focus is on breast and pancreatic cancers. We are atttempting to identify in vitro correlates of in vivo antitumor immunity induced by vaccine strategies developed in the laboratory and currently under study in the clinics. view more
