The result was clear: The combination boosted immunity to tumors.<\/p>\n\n\n\n<p>The paper&#8217;s first author, Marc Pellegrini, MD, PhD, is a postdoctoral fellow receiving support from the Irvington Institute Postdoctoral Fellowship Program of the Cancer Research Institute.<\/p>\n\n\n\n<p>\u00abWe are extremely excited because our research has revealed the unexpected ways IL-7 works to break down barriers that naturally block the immune response to tumors. This is important because current vaccine approaches for immune therapy induce a response in just 1%&nbsp;to 3% of patients,\u00bb says Dr. Ohashi, a senior scientist in signaling biology who holds a Canada Research Chair in Autoimmunity and Tumor Immunity.<\/p>\n\n\n\n<p><a title=\"Dr. Tak Mak\" href=\"https:\/\/www.uhnresearch.ca\/researchers\/profile.php?lookup=3816\" target=\"_blank\" rel=\"noopener\">Dr. Tak Mak<\/a>, co-author and CFIBCR director, says: \u00abThe promise of using the body&#8217;s own defenses to fight cancer is enormous. The day is coming when immunotherapy may help spare cancer patients the toxic side effects of traditional therapies and greatly improve their quality of life while treating the disease. This is why we are planning to expand our immunotherapy research program at PMH.\u00bb Dr. Mak and Dr. Ohashi are professors at the University of Toronto in the Department of Medical Biophysics and Immunology.<\/p>\n\n\n\n<p>Dr. Mak is a member of the Cancer Research Institute Scientific Advisory Council, and has trained twelve CRI-funded fellows in his laboratory at the University of Toronto.<\/p>\n\n\n\n<p>This research was also financially supported by grants and fellowships from the Canadian Institute for Health Research, the Ontario Institute for Cancer Research, the Terry Fox Foundation, the National Cancer Institute of Canada, the Boninchi Foundation (Geneva) and the Irvington Institute Fellowship Program of&nbsp;the Cancer Research Institute (New York).<\/p>\n\n\n\n\n<p>Reference: <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/?term=19396174\" target=\"_blank\" rel=\"noreferrer noopener\">Adjuvant IL-7 antagonizes multiple cellular and molecular inhibitory networks to enhance immunotherapies.<\/a>\u00a0Pellegrini M, Calzascia T, Elford AR, Shahinian A, Lin AE, Dissanayake D, Dhanji S, Nguyen LT, Gronski MA, Morre M, Assouline B, Lahl K, Sparwasser T, Ohashi PS, Mak TW.
