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.
