Abstract:
Expression of the 43 kDa glycoprotein (gp43) was analysed in several Paracoccidioides brasiliensis isolates. Using one- and two-dimensional analysis of crude cellular extracts, it was shown that protein expression in yeast and mycelium was dependent on the isolate analysed. In two strains, in both yeast and mycelium cells. gp43 was present, whereas expression was restricted to the yeast phase of two other strains. The clinical implications of this phase-specific gp43 expression are uncertain.
