To identify genes encoding adhesins that mediate the binding of
Candida albicans to endothelial cells, a genomic library
from this organism was constructed and used to transform
Saccharomyces cerevisiae. These transformed organisms were
screened for adherence to endothelial cells, and a highly adherent
clone was identified. The adherence of this clone to endothelial cells
was over 100-fold greater than that of control S. cerevisiae transformed with the empty plasmid. This clone also
exhibited enhanced adherence to epithelial cells. The C. albicans gene contained within this clone was found to be
ALS1. These results indicate that ALS1 may
encode a candidal adhesin.
