New drug discovery and antibody engineering

The main focus of our group is to develop humanized antibody-based and immunogen-based therapeutics, which target key molecules involved in IgE-mediated allergic pathway. We are also developing new technology platforms for improved antibody engineering. One such program is to develop humanized antibody against CεmX domain in human membrane-bound IgE, for the purpose of controlling IgE-expressing B lymphocytes. CεmX, discovered by our group, is a 52 a.a. domain with a unique sequence. Anti-CεmX, if successfully developed, may be used in combination with an anti-IgE antibody, such as omalizumab (trade name Xolair), which is also derived from Dr. Chang's invention and which is approved for allergic asthma.
