Research Interests
The main focus in my lab is to study the biology and pathogenicity of a major fungal pathogen of humans, Candida albicans, and the interactions between C. albicans and its hosts. As a commensal, C. albicans frequently causes irritating and recurrent infections, including oral thrush and vaginal candidiasis. In immunocompromised patients, C. albicans can become invasive and causes life-threatening systemic infections. Moreover, C. albicans can also gain entry into the bloodstream (candidaemia) during procedures associated with the implantation of medical devices. As such, this organism has emerged as the fourth most common blood-bone infection in the US and candidaemia is a significant nosocomial infection. Moreover, a minor project is to elucidate molecular mechanisms of multidrug resistance of Acinetobacter baumannii. The projects currently underway include:
(1) Environmental sensing, signal integration and C. albicans pathogenesis.
During its natural history in the host, C. albicans encounters a wide variety of environmental conditions, including changing nutrients, pH, and antimicrobial mediators. One of the features that allow C. albicans to transition from a commensal organism to a successful pathogen is its ability to sense these complex environmental signals and respond by controlling cell growth/proliferation and hyphal morphogenesis, forming biofilm and expression of associated virulence determinants. Our immediate objective is to characterize the roles of a new Rhb1-mediated signaling/regulatory pathway for integrating multiple environmental signals, cell growth/proliferation and virulence. (Tsao et al., 2009; Chen et al., 2012; Hsu et al., 2013). In addition, we also study the response of C. albicans to human antimicrobial peptide LL-37 (Tsai et al., 2014a; Chang et al., 2011; Tsai et al., 2011a and 2011b) and molecular mechanisms of biofilm formation (Chen et al., 2015; Tsai et al., 2014b; Wang et al., 2010).
Iron is important for the microbial pathogen-host interaction. The availability of iron serves as an important signal for the expression of virulence determinants in pathogens, and iron withholding is a defense mechanism of hosts against microbial infections. Using functional genomics and molecular genetics, we have identified genes whose expression is modulated by iron availability and also identified the transcriptional factors, Sfu1 and Hap43, involved in this regulation (Lan et al., 2004; Hsu et al., 2011; Hsu et al., 2013).(2) Interaction networks between C. albicans and host.
In collaboration with Dr. Y.-J. Chuang’s group (NTHU), we demonstrate that zebrafish can be a useful model to study C. albicans pathogenesis (Chao et al., 2010). Currently, in collaboration with Drs. B.-S. Chen, W.-P. Hsieh and D.-S. Wong’s group (NTHU), C. albicans-host interaction networks are investigated using functional genomic and systems biological approaches (Chen et al., 2008; Yang et al., 2010; Hsu et al., 2011; Wang et al., 2012; Kuo et al., 2013; Wang et al., 2013; Chen et al., 2013; Wang et al., 2014; Lin et al., 2014a; Lin et al., 2014b).
Some of our work in (1) and (2) are reviewed in Tsai et al., (2013).(3) Multidrug resistance in Acinetobacter baumannii: epidemiology and its molecular mechanisms.
Acinetobacter baumannii has emerged as a leading nosocomial pathogen. Because nosocomial isolates exhibit a remarkable ability to develop antibiotic resistance rapidly, A. baumannii infection pose a great challenge. Currently, another project of my lab is working in collaboration with Dr. M.-F. Lin’s group (NTU Hospital-ChuTung Branch). Using molecular epidemiology and molecular biology approaches, we investigated the distribution of various drug-resistant A. baumannii strains in Taiwan (Lin et al., 2011 and 2013). In addition, we are also studying role of the BaeSR two-component signaling system in regulation of a wide variety of efflux pumps, and its correlation with susceptibility of different antibiotics (Lin et al., 2014c, 2014d, 2014e, 2015).
Our work related to A. baumannii is reviewed in Lin et al., (2014d).
