Dr. Janis Taube is a professor of dermatology and pathology at the Johns Hopkins University School of Medicine and a member of the Johns Hopkins Kimmel Cancer Center. Her area of clinical expertise is dermatopathology. Dr. Taube serves as the Director of the Division of Dermatopathology and as the Assistant Director of the Dermatoimmunology Laboratory at the School of Medicine.

Dr. Taube received her undergraduate degree in engineering from Duke University. She earned her M.D. from Tulane University and her M.Sc. in molecular medicine from University College London. She completed her residency in pathology at Johns Hopkins where she also served as the chief resident, before undertaking a dermatopathology fellowship at Stanford University. In 2009, Dr. Taube returned to Johns Hopkins for her certification in the Melanoma Clinic.

She is one of the lead scientific researchers in the Department of Dermatology at Johns Hopkins. Her research is related to the study of the B7-H1 molecule. Dr. Taube and her team are seeking to identify the signaling mechanisms behind B7-H1 expression.

In addition to running her own research laboratory, she serves as the co-Director of the Mark Foundation Center for Advanced Genomics and Imaging and also as the co-Director of the Tumor Microenvironment Core Laboratory for the Bloomberg~Kimmel Institute for Cancer Immunotherapy.

Research & Publications

Research Summary

Dr. Taube’s research interests center on the immune evasion by solid tumors, specifically studying the PD-L1/PD-1 axis, and the identification of potential biomarkers that can help pre-select patients with advanced malignancies for novel immunotherapeutic treatment regimens. This requires a focus on immunohistochemical and molecular methods for identifying cell surface antigens and signaling pathways in paraffin-embedded tissue. Dr. Taube’s lab described PD-L1 (B7-H1)-mediated adaptive immune resistance by melanoma, a finding which has now been extended to other tumor types. Dr. Taube’s laboratory also developed the PD-L1 immunohistochemical assay and scoring system for the first in-human anti-PD-1 and anti-PD-L1 immunotherapies, versions of which are now FDA approved. Ongoing laboratory efforts focus on further characterizing the local, pre-treatment tumor microenvironment with the aim of developing rational treatment combinations and improving patient selection algorithms for immunotherapeutic regimens. To that end, Dr. Taube has been collaborating with Dr. Szalay, a world expert in Astronomy and Big Data, to develop a new multispectral tissue imaging platform termed ‘AstroPath’ to further biomarker development.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
