Neither virus increased expression of human beta defensin 2 (hBD-2) LGX818 mouse mRNA over supernatants from uninfected lymphoblast controls. HIV-1 also failed to induce mRNA of four

additional innate immunity-related genes. Similar results were obtained with oral monolayer epithelial cells. Interestingly, the X4-tropic virus inhibited mRNA expression of hBD-2, and of three of the other factors, at higher dosages in the differentiated oral epithelium but not the monolayers. The failure of HIV-1 to induce innate immune factors in the differentiated epithelium was not due to a lack of tissue penetration, as we detected fluorescence-tagged virions up to 30 mm deep from the apical surface. HIV-1 does not trigger de novo innate immune factor synthesis in oral epithelium, pointing to the role of a constitutive innate immunity for protection against HIV-1 in the oral cavity.”
“Background. Loeys-Dietz syndrome (LDS) is a recently recognized connective tissue

disorder (CTD) caused by mutations in transforming growth factor-beta receptor (TGFBR) 1 and TGFBR2. Surgical outcomes of aortic repair in patients with LDS are poorly known.\n\nMethods. We enrolled 16 patients with TGFBR mutations identified by gene analysis in this study. Between 1993 and 2011, they underwent 41 aortic surgical Akt inhibitor procedures. Ten patients (group D: dissection group) underwent aortic repair for acute or chronic aortic dissection as a first surgical intervention, and 6 patients (group N: nondissection group) underwent surgical treatment for aortic root dilatation. The mean follow-up period was 103.7 +/- 92.3 months (range, 2-276 months).\n\nResults. There were no in-hospital deaths. In group N, valve-sparing root replacement (VSRR) was performed in all patients. The residual aorta in 9 patients (90%) from group D required Stattic solubility dmso further repairs, 3 times on average. Moreover, in 4 patients (40%), the aorta was entirely replaced in serial procedures. In group N, aortic dissection occurred in only 1 patient

(17%). The aortic event-free rates at 5 years were 40% in group D and 80% in group N, respectively (p = 0.819). One late death due to arrhythmia occurred 1 month after VSRR. The cumulative survival rates at 5 years were 100% in group D and 83% in group N, respectively (p = 0.197).\n\nConclusions. Surgical outcomes for patients with LDS were satisfactory. Once aortic dissection occurred, the aorta expanded rapidly, requiring further operations. Therefore, early surgical intervention may improve prognosis by preventing a fatal aortic event.
