The in vivo expression of Candida albicans secreted aspartyl proteinase (SAP1-SAP8) and phospholipase B (PLB1 and PLB2) genes was analyzed in 137 human subjects with oral and vaginal candidiasis or carriage. Total RNA was isolated from whole unstimulated saliva or vaginal swabs, and the expression of SAP1-8 and PLB1-2 was evaluated by reverse-transcriptase polymerase chain reaction using specific primer sets. A spectrum of SAP gene expression profiles was obtained from different C. albicans strains during symptomatic disease and asymptomatic carriage. SAP2 and SAP5 were the most common genes expressed during both infection and carriage. SAP1, SAP3, SAP4, SAP7, SAP8, and PLB1 expression was correlated with oral disease, whereas SAP1, SAP3, and SAP6-SAP8 expression was correlated with vaginal disease. Furthermore, SAP1, SAP3, and SAP8 were preferentially expressed in vaginal, rather than oral, infections. This study demonstrates the differential expression of the hydrolytic enzyme genes in humans and correlates the expression of specific Candida species virulence genes with active disease and anatomical location.

In order to analyze the in vivo expression of Candida albicans secreted aspartyl proteinases (SAP) in human vaginal infection, the vaginal secretion from 29 human subjects was collected by vaginal swab, and the expression of SAP1-SAP6 was detected by reverse-transcriptase polymerase chain reaction using specific primer sets. It was found that Sap2 and Sap5 were the most common genes expressed during infection; Sap3 and Sap4 were detected in all subjects and all 6 SAP genes were simultaneously expressed in some patients with vaginal candidiasis. It was suggested that the SAP family is expressed by Candida albicans during infection in human and that Candida albicans infection is associated with the differential expression of individual SAP genes which may be involved in the pathogenesis of vaginal candidiasis.

In order to investigate the expression of Th1 and Th2 cytokines in the vaginal candidiasis caused by Candida, the fungal vaginitis model was established in female ICR mice by intravaginal inoculation of suspension of C. albicans after the animals were pretreated with estradiol. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of IL-2, IL-4, IL-10 and TGF-beta1 in the vagina in the mice of different groups at different time points after the beginning of the experiment. The average expression level of IL-2 mRNA in group D (estrogen-treated mice) was significantly higher than that in groups H (estrogen-untreated mice) and I (control group) on the day 2. The average expression level of IL-4 mRNA in group D was significantly higher than that in groups I and H on the day 5. The average expression level of IL-10 mRNA in group D was significantly higher than that in groups H and I from day 7 to 11. The average expression level of TGF-beta1 mRNA in group D was significantly higher than that in groups H and I at all time points. It was concludes that the high-level expression of IL-2 mRNA during early infection was associated with clearance of mucosal C. albicans, and the high-level expression of IL-10 mRNA during late stage of the infection was related to susceptibility to infection. TGF-beta1 may play a predominant role when the virtual absence of changes in other Th-type cytokines during infection.
