Study Identifies How Ovarian Cancer Protects Itself, Paves Way for Improved Immunotherapy Approach
 Researchers at the Icahn School of Medicine at Mount Sinai have discovered a way that ovarian cancer tumors manipulate their environment to resist immunotherapy and identified a drug target that could overcome that resistance. The study, published in the October 30 online issue of Cell used a cutting-edge spatial genomics technology and preclinical animal models, with tumor specimens from ovarian cancer patients further validating the findings. They found that ovarian cancer cells produce a molecule called Interleukin-4 (IL-4), which is typically associated with asthma and the skin condition eczema, also known as atopic dermatitis. The study went on to find that the cancer cells used IL-4 to create a protective environment that kept away killer immune cells, making the tumors resistant to immunotherapy. A drug, dupilumab, which blocks IL-4's activity, has been approved by the Food and Drug Administration (FDA) and is already used to treat asthma and eczema. This new study suggests dupi
