Research Description


Dr. Ji’s research interest is to perceive mechanisms underlining the regulatory potential for human IgA antibody. In a joint effort with Drs. Kimberly, Wu and Edberg, we previously identified a naturally-occurred variant S248G (SNP844A/G) at cytoplasmic domain of FcαRI α-chain that alters pleiotropic IgA effector functions, showing significant impact in rheumatic and autoimmune diseases (J Immunol 2007, 178:3973; PNAS 2011, 108:20736-20741). Through genomic and proteomic approaches we are establishing serine-based regulatory mechanism that couples FcαRI genetic diversity to IgA inflammatory multiplicity. By following the very essence of IgA effector features in health and disease, our continuing effort is to elucidate FcαRI α-chain and γ-chain signaling pathways as well as other molecular insights unique for IgA-mediated feedback regulation in parallel with those of FcγRs for IgG response.
