Modulating The Tumor Microenvironment To Improve Immunotherapy Treatments, Lleayem Nazario-Johnson, David Rowley

Senior Honors Projects

Advances in immunotherapy are revolutionizing the treatments of certain cancers, especially those in the blood. However, wider applications for eradicating solid tumors have been slow to emerge. A likely reason is the presence of myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment that secrete immunosuppressive molecules which attenuate the attack of immune cells. We hypothesize that small molecule Wnt/Beta- Catenin inhibitors can be used to modulate the immunosuppressive actions of MDSCs and increase the effectiveness of immunotherapy treatments, such as with chimeric antigen receptor (CAR) T-cells. The Wnt/Beta-Catenin Pathway has been shown to be a crucial driving force behind the …
