Objectives: To verify the prevalence of E6/E7 RNAm expression of HPV in patients with negative cervicovaginal cytology, ASC-US and LSIL;to correlate with negative anatomopathological exams and/or squamous intraepithelial neoplasy grade I (SIN 1) of the lower genital tract (LGT);to relate the RNAm expression with viral infection types;to assess the genotyping in single infections. Methods: Findings from 825 women submitted to E6/E7 RNAm survey and 422 women submitted to LGT biopsies were analyzed. Results: A larger percentage of E6/E7 in ASC-US and LSIL cytologies occurred. Negative results of RNAm expression were in accordance with negative cytologies and negative anatomopathological exam. In positive cases, the infection by a single HPV type was most prevalent, with the type 16 being the most common. Conclusions: the expression of mRNA was most prevalent in ASC-US and LSIL cytologies, comparing with the negative ones. The findings of SIN 1 biopsies were related to the positive expression of mRNA and negative cytologies;the negative expression was in agreement with negative anatomopathological exam. The infection by a HPV type was more frequent in cases of positive expression, the HPV type 16 being most frequently found. Patients with low grade intraepithelial lesion cytologies had a higher percentage of multiple infections.

Dectin- 1 isoforms contribute to distinct Th 1/Th 17 cell activation in mucosal candidiasis

Cellular & Molecular Immunology 2012年第3期9卷 276-286页

The recognition of p-glucans by dectin-1 has been shown to mediate cell activation, cytokine production and a variety of antifungal responses. Here, we report that the functional activity of dectin-1 in mucosal immunity to Candida albicans is influenced by the genetic background of the host. Dectin-1 was required for the proper control of gastrointestinal and vaginal candidiasis in C57BIJ6, but not BALB/c mice; in fact, the latter showed increased resistance in the absence of dectin-1. The susceptibility of dectin-l-deficient C57BL/6 mice to infection was associated with defects in IL-17A and aryl hydrocarbon receptor-dependent IL-22 production and in adaptive Th I responses. In contrast, the resistance of dectin- 1-deficient BALB/c mice was associated with increased IL-17A and IL-22 production and the skewing towards Thl/Treg immune responses that provide immunological memory. Disparate canonical/ noncanonical NF-KB signaling pathways downstream of dectin-1 were activated in the two different mouse strains. Thus, the net activity of dectin-1 in antifungal mucosal immunity is dependent on the host＇s genetic background, which affects both the innate cytokine production and the adaptive Th1/Th17 cell activation upon dectin-1 signaling.
