Dr. Jian Zhang had his Research on Genetic Target CBLB and Drug Resistant Infections Highlighted by The Ohio State University 


Disseminated candidiasis has become one of the leading causes of hospital-acquired blood stream infections with high mobility and mortality. However, the molecular basis of host defense against disseminated candidiasis remains elusive, and treatment options are limited. Here we report that the E3 ubiquitin ligase CBLB directs polyubiquitination of dectin-1 and dectin-2, two key pattern-recognition receptors for sensing Candida albicans, and their downstream kinase SYK, thus inhibiting dectin-1- and dectin-2-mediated innate immune responses. CBLB deficiency or inactivation protects mice from systemic infection with a lethal dose of C. albicans, and deficiency of dectin-1, dectin-2, or both in Cblb–/– mice abrogates this protection. Notably, a systemically delivered Cblb-specific small interfering RNA administered after C. albicans infection lowered kidney fungal burden and prevented death in mice. Our data reveal that CBLB is crucial for homeostatic control of innate immune responses mediated by dectin-1 and dectin-2. Our data also indicate that CBLB represents a potential therapeutic target for protection from disseminated candidiasis.
