  • Alison Moliterno Lab

    Principal Investigator:
    Alison Moliterno, M.D.
    Medicine

    The Alison Moliterno Lab studies the molecular pathogenesis of myeloproliferative disorders (MP...Ds), including polycythemia vera, essential thrombocytosis and idiopathic myelofibrosis. Our research is focused on the genetic and epigenetic lesions associated with MPDs, with the goal of improving diagnosis and treatment for these disorders. view more

  • Andrew Lane Lab

    The Lane laboratory is focused on understanding molecular mechanisms underlying chronic rhinosi...nusitis, particularly the pathogenesis of nasal polyps, as well as inflammation on the olfactory epithelium. Diverse techniques in molecular biology, immunology, and physiology are utilized to study epithelial cell innate immunity, olfactory loss, and response to viral infection. Ongoing work explores how epithelial cells of the sinuses and olfactory mucosa participate in the immune response and contribute to chronic inflammation. The lab creates and employs transgenic mouse models of chronic nasal/sinus inflammation to support research in this area. Collaborations are in place with the School of Public Health to explore mechanisms of anti-viral immunity in influenza and COVID-19. view more

    Principal Investigator:
    Bert Vogelstein, M.D.
    Oncology

    The Bert Vogelstein Laboratory seeks to develop new approaches to the prevention or treatment o...f cancers through a better understanding of the genes and pathways underlying their pathogenesis.

    Our major focus is on cancers of the colon and rectum. We have shown that each colon neoplasm arises from a clonal expansion of one transformed cell. This expansion gives rise to a small benign colon tumor (called a polyp or adenoma). This clonal expansion and subsequent growth of the tumors appears to be caused by mutations in oncogenes and tumor suppressor genes, and the whole process is accelerated by defects in genes required for maintaining genetic instability. Mutations in four or five such genes are required for a malignant tumor to form, while fewer mutations suffice for benign tumorigenesis. As the mutations accumulate, the tumors become progressively more dangerous.

    Current studies are aimed at the further characterization of the mechanisms through which these genes act, the identification of other genes that play a role in this tumor type, and the application of this knowledge to patient management.

  • Brain Tumor Cancer Genetics Lab

    Lab Website

    The lab explores the genetic underpinnings that drive the pathogenesis of a variety of primary ...central nervous system neoplasms. We are interested in exploiting genetic changes for both diagnostic and therapeutic purposes. Our lab is currently working on understanding the extreme responders and extreme clinical phenotypes of brain and spinal cord tumors to identify factors that may modulate responses to therapy. view more

  • Brendan Cormack Laboratory

    The Brendan Cormack Laboratory studies fungal pathogenesis, particularly the host-pathogen inte...raction for the yeast pathogen Candida glabrata.

    We are trying to identify virulence genes (genes that evolved in response to the host environment) by screening transposon mutants of C. glabrata for mutants that are specifically altered in adherence to epithelial cells, in survival in the presence of macrophages and PMNs. We also screen mutants directly in mice for those unable to colonize or persist in the normal target organs (liver, kidney and spleen).

    We also focus research on a family of genes--the EPA genes--that allow the organism to bind to host cells. Our research shows that a subset of them are able to mediate adherence to host epithelial cells. We are trying to understand the contribution of this family to virulence in C. glabrata by figuring out what the ligand specificity is of different family members, how genes are normally regulated during infection, and what mechanisms normally act to keep the genes transcriptionally silent and how that silence is regulated.

  • David Graham Lab

    Principal Investigator:
    David Graham, Ph.D., M.S.
    Molecular and Comparative Pathobiology

    The David Graham Lab studies the consequences of HIV interactions with the immune system, the r...esulting pathogenesis and how to sabotage these interactions. We apply advanced technologies like mass spectrometry to dissect processes at the molecular level. We are also actively involved in cardiovascular research and studies the ways proteins are organized into functional units in different cell types of the heart.

    Major projects in our lab are organized into three major areas: (1) H/SIV pathogenesis and neuropathogenesis, (2) Cardiovascular disease, and (3) High technology development

  • Diane Griffin Lab

    Principal Investigator:
    M. Griffin, M.D., Ph.D.
    Medicine

    Research in the Diane Griffin Lab focuses on the viral, cellular and immunologic determinants o...f diseases caused by alphaviruses and the measles virus. Our current studies aim to understand the immune-system mechanisms behind viral clearance and disease enhancement. Our team is also working to understand the pathogenesis of the measles virus, with a focus on developing new vaccines and learning how the virus induces immunosuppression. view more

  • Douglas Ball Lab

    Principal Investigator:
    Douglas Ball, M.D.
    Medicine

    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

  • Fuchs Laboratory

    Lab Website

    The Fuchs Laboratory uses cellular electrophysiology, immunolabeling and electron microscopy to... study synaptic connections between sensory hair cells and neurons in the cochlea. One effort focuses on an unusual cholinergic receptor that mediates efferent inhibition of hair cells, driving discovery of the molecular mechanisms, and offering a target for protection against acoustic trauma. A second topic concerns the small number of unmyelinated "type II" afferent neurons whose synaptic connectivity and response properties argue for a role as the pathway for noxious (too loud) sound. Our studies are motivated by curiosity about fundamental mechanisms, and to provide a foundation for understanding cochlear pathogenesis. view more
