A study led by researchers in the Division of Allergy and Immunology. reports findings that offer insight into new therapeutic strategies and diagnostics for severe food allergies triggered by immunoglobin E (IgE). The study, published in the journal Immunity, reveals the discovery of IL-9-producing mucosal mast (MM9) cells that produce large amounts of an inflammatory protein, interlukin 9 (IL-9), known to amplify anaphylactic shock in response to certain foods. “Our study suggests that although you need to have some level of IgE to trigger a food allergy response, you also have to produce MMC9 cells to get a severe response and anaphylaxis,” says Yui-Hsi Wang, PhD, the study’s co-first author. “Without these cells you will not get severe food allergies.”
We are excited to announce the launch of a new, innovative, Master’s Program at Cincinnati Children’s Hospital Medical Center, in conjunction with the University of Cincinnati. The Biomedical Research Master’s Program is born from the recognition that there is a growing job market, in both academia and industry, for scientists who have a strong foundation in the basic methods of biomedical laboratory research, and are trained in emerging techniques and technologies. We have designed this new program to provide students with extensive hands-on training in basic molecular biology, cell biology and biochemistry as well as rotations in our state-of-the art core facilities where they will be provided one-on-one training in the use of stem cell techniques, the generation of transgenic animals, flow-sorting, histology, high-end imaging techniques, animal handling, and single-cell techniques. Our first class of five students started classes on August 24 and we are expecting that they will graduate in May of 2017. If you would like more information this new and exciting program, please contact us at BMRMSProg@cchmc.org.
