Research Description

As an integral part of adaptive immunity, B lymphocytes play fundamental roles in defensing against infection and illness. During B 购宝钱包 differentiation and antigen activation, extremely diversified antibody repertoires are generated through a highly coordinated spatio-temporal regulation with each B 购宝钱包 expressing a unique antibody, which is pivotal for the immune system to be “adaptable” to the numerous antigens. Moreover, B 购宝钱包 s contribute to the establishment of advanced lymphoid structures and are involved in antigen presenting, tissue homeostasis, and immune responses to tumors. B 购宝钱包 dysfunction is associated with various types of diseases including immunodeficiency, autoimmunity, and tumorigenesis. We have devoted major efforts to the development of several innovative high-throughput sequencing-based approaches and addressed the major long-standing enigma of how antibody genes are diversified at the molecular level. We have also developed a rapid mouse model for B-购宝钱包 lymphomas and provided a new general approach for the generation of genetically complex mouse disease models. In the future, we will continue to develop and employ multidisciplinary state-of-the-art technologies and take multi-scale approaches to further elucidate mechanisms that orchestrate B 购宝钱包 differentiation and function, and antibody diversification, and mechanisms that underlie the related immunological disorders and cancer. Based on the new understanding from the basic research, we will ultimately generate innovative platforms and strategies to develop vaccines and therapeutic antibodies to fight against human diseases.
