1 Physicochemical a spects of multilayered polyelectrolyte f ilms Multilayered polyelectrolyte films are obtained by al-ternated depositions on a solid surface of polyanions and polycations[1].The driving force for the build-up results from the charge excess which appears on the top of the film after each new polyelectrolyte *** film top becomes thus positively(respectively negatively)charged when the film is ending by a polycation(respec-tively polyanion).Various polyelectrolyte systems have been used to realize such architectures,in particular syn-thetic polyelectrolytes(poly-styrene sulfonate:PSS,poly-allylylamine:PAH,etc.);polypeptides(poly-glutamic acid:PGA,poly-lysine:PLL,etc.),polysaccharides[-](hyaluronane:HA,chitosan:Chi,etc.).

Activation of defense Response Pathways by OGs and Fig22 Elicitors in Arabidopsis Seedlings

Molecular Plant 2008年第3期1卷 423-445页

We carried out transcriptional profiling analysis in 10-d-old Arabidopsis thaliana seedlings treated with oligogalacturonides （OGs）, oligosaccharides derived from the plant cell wall, or the bacterial flagellin peptide Fig22, general elicitors of the basal defense response in plants. Although detected by different receptors, both OGs and Fig22 trigger a fast and transient response that is both similar and comprehensive, and characterized by activation of early stages of multiple defense signaling pathways, particularly JA-associated processes. However, the response to Fig22 is stronger in both the number of genes differentially expressed and the amplitude of change. The magnitude of induction of individual genes is in both cases dose-dependent, but, even at very high concentrations, OGs do not induce a response that is as comprehensive as that seen with Fig22. While high doses of either microbe-associated molecular pattern （MAMP） elicit a late response that includes activation of senescence processes, SA-dependent secretory pathway genes and PR1 expres- sion are substantially induced only by Fig22. These results suggest a lower threshold for activation of early responses than for sustained or SA-mediated late defenses. Expression patterns of amino-cyclopropane-carboxylate synthase genes also implicate ethylene biosynthesis in regulation of the late innate immune response.

AIM To describe factors associated with treatment failure and frequency of resistance-associated substitutions(RAS).MetHODS Human immunodeficiency virus(HIV)/hepatitis C virus(HCV) coinfected patients starting a first direct-acting antiviral(DAA) regimen before February 2016 and included in the French ANRS CO13 HEPAVIH cohort were eligible. Failure was defined as:(1) non-response [HCV-RNA remained detectable during treatment, at end of treatment(EOT)]; and(2) relapse(HCVRNA suppressed at EOT but detectable thereafter). Sequencing analysis was performed to describe prevalence of drug class-specific RAS. Factors associated with failure were determined using logistic regression *** Among 559 patients, 77% had suppressed plasma HIV-RNA lapses(17, 77%) then undefined failures(3, 14%) and non-responses(2, 9%). Mean treatment duration was 16 wk overall. Posttreatment NS3, NS5 A or NS5 B RAS were detected in 10/14 patients with samples available for sequencing analysis. After adjustment for age, sex, ribavirin use, HCV genotype and treatment duration, low platelet count was the only factor significantly associated with a higher risk of failure(OR: 6.5; 95%CI: 1.8-22.6). CONCLUSION Only 3.9% HIV-HCV coinfected patients failed DAA regimens and RAS were found in 70% of those failing. Low platelet count was independently associated with virological failure.
