Research Interests

The diversification of B cell-generated antibody is the hallmark of adaptive immunity, which facilitates the elimination of harmful antigens. The antibody diversification is from RAG-mediated V(D)J recombination, activation-induced cytidine deaminase (AID)-initiated class switch recombination (CSR) and V(D)J exon somatic hypermutation (SHM). While the off-targets of RAG- and AID-mediated recombination or mutation severely affect the genome stability and human health. Our group uses the combination of gene editing and genomics to systematically study the mechanism of antibody maturation and diversification during B cell development, and the roles of dynamic chromatin structure in maintaining genomic stability, which can also contribute to the understanding of immunological deficiency-related diseases and genome instability-related diseases.
