ALS2 and periodontal disorder: Building on that work, the present study analyzed the different molecular expression patterns of ALS (ALS1, ALS2, ALS3, ALS4, ALS5, ALS6, ALS7, and ALS9) and SAP (SAP1-SAP10) family genes in C. albicans strains isolated from patients with periodontal disease in an in vitro infection model using an HGF cell line.
