Description of Research Expertise

The Powell Lab is actively investigating the application of immune-based therapy for cancer. Building on interrogations in basic T cell biology in the lab, bench-to-bedside translational immunology is being developed, with a strong focus on T cell-based therapy for cancer.

One obstacle to successful immunotherapy is the lack of highly avid, tumor-reactive T cells in multiple cancers. One current focus of the Powell lab is to generate/isolate high avidity, tumor-reactive T cells from heterogenous tumor infiltrating lymphocyte populations in traditionally "non-immunogenic" cancers utilizing novel culture conditions and T cell capture techniques. This in turn will permit downstream studies of T cell receptor (TCR) isolation, cancer antigen identification and molecular characterization of naturally occurring tumor-reactive T cells in human cancer.

A secondary field of study is the de novo generation of tumor-reactive T cells through genetic engineering methods. One approach relies on the isolation and cloning of T cell receptors (TCRs) that confer non-reactive T cells with specific and potent immune function following gene transfer via recombinant lentivirus or retrovirus. Another approach relies upon the use of chimeric antigen receptors (CARs) that confer T cells with the MHC-independent specificity of a tumor antigen-specific antibody and potent T cell activity delivered by TCR and costimulatory domains. The Powell Lab also employs the CAR approach to test the function of novel costimulatory signals in anti-tumor immunity.

The Powell lab pioneered the use of universal immune receptors as a novel platform for CAR screening and for the tailoring of antigen specificity for simultaneous or sequential targeting of target antigens, and is actively expanding this field of study.

Other current efforts include the exploration of immunomodulation to potentiate endogenous antitumor T cell responses, use of bispecific antibodies, pharmacological sensitization of tumor cells to immune attack, tumor vasculature targeting, preclinical validations, clinical translation and trial support.
