Dr. Huan Huang conducts the studies on Trypanosoma cruzi (T. cruzi), a parasite which causes Chagas disease. The researches include molecular biology of the parasite, pathogenesis of Chagas disease and the genetic techniques in this organism. His laboratory studies protein kinases and kinase signaling pathways in T. cruzi, identifying and characterizing components in cAMP-dependent protein kinase (PKA) and Mitogen activated protein kinase pathways in T. cruzi. These findings have established a solid basis for further research in this pathogen and the knowledge can be used for drug development. Recently, his group advanced molecular genetics in T. cruzi by designing a modified pTREX vector which uses an N-terminal fusion of a ligand-controlled destabilization domain (ddFKBP) to a gene/protein of interest. This vector system allows rapid and reversible protein expression and efficient functional analysis of proteins in different T. cruzi life cycle stages. In addition, his group is creating transgenic T. cruzi for the study of disease mechanism and for vaccine strains. The inducible suicide vector systems in T. cruzi have been established recently using the degradation domain based on the Escherichia coli dihydrofolate reductase (ecDHFR) linked with toxic or detrimental proteins. These vector systems can be introduced into this organism to create attenuated live parasites which can be induced to undergo a self-destruction process. The technique may lead to a breakthrough in T. cruzi vaccine design.
