皮肤益生素霜与皮炎消擦剂联合治疗面部脂溢性皮炎的疗效观察

脂溢性皮炎是皮肤科常见病和多发病,因发生了面部,美容治疗患者很多,目前多认为此病因是皮脂腺分泌旺盛,表皮真菌感染所致。自1998年以来,我们试用皮肤益生素与皮炎消擦剂联合治疗,增强了抑菌、杀菌作用和平衡腺体分泌的功能。78例患者临床观察使用皮炎消治疗总有效率为72．2％。皮肢益生素与皮炎消联合治疗总有效率为92．5％。疗效增加20．3％,效果显著。

Studying fungal pathogens of humans and fungal infections: fungal diversity and diversity of approaches

Seminal work by Louis Pasteur revealed the contribution of fungi – yeasts and microsporidia to agroindustry and disease in animals, respectively. More than 150 years later, the impact of fungi on human health and beyond is an ever-increasing issue, although often underestimated. Recent studies estimate that fungal infections, especially those caused by Candida, Cryptococcus and Aspergillus species, kill more than one million people annually. Indeed, these neglected infections are in general very difficult to cure and the associated mortality remains very high even when antifungal treatments exist. The development of new antifungals and diagnostic tools that are both necessary to fight fungal diseases efficiently, requires greater insights in the biology of the fungal pathogens of humans in the context of the infection, on their epidemiology, and on their role in the human mycobiota. We also need a better understanding of the host immune responses to fungal pathogens as well as the genetic basis for the increased sensitivity of some individuals to fungal infections. Here, we highlight some recent progress made in these different areas of research, in particular based on work conducted in our own laboratories. These progresses should lay the ground for better management of fungal infections, as they provide opportunities for better diagnostic, vaccination, the development of classical antifungals but also strategies for targeting virulence factors or the host.     

Coding fungal tandem repeats as generators of fungal diversity

Coding tandem repeats are adjacent sequences that are directly repeated. The repeated units can be identical or partially degenerate. They are completely contained within a coding sequence and are composed of repeated units in which copy number does not disrupt the reading frame. They have been observed in viruses, prokaryotes and eukaryotes. The benefits offered by repeats include the modular construction of new proteins and introduction of rapidly evolving protein sequences which allow faster adaptation to new environments. Here we review the subject of tandem repeats and their relevance in fungi. Emphasis is given to repeat-containing fungal cell wall proteins and their role in generating diversity, adaptation to the environment, immunogenicity, adhesion, and pathogenesis. We describe in detail the recent studies analyzing coding tandem repeats in the model yeast Saccharomyces cerevisiae and the important human pathogens Candida albicans and Aspergillus fumigatus. Numerous unanswered questions are highlighted, providing a rich hunting ground for future research.     

Permeabilization of fungal membranes by plant defensins inhibits fungal growth

We used an assay based on the uptake of SYTOX Green, an organic compound that fluoresces upon interaction with nucleic acids and penetrates cells with compromised plasma membranes, to investigate membrane permeabilization in fungi. Membrane permeabilization induced by plant defensins in Neurospora crassa was biphasic, depending on the plant defensin dose. At high defensin levels (10 to 40 microM), strong permeabilization was detected that could be strongly suppressed by cations in the medium. This permeabilization appears to rely on direct peptide-phospholipid interactions. At lower defensin levels (0.1 to 1 microM), a weaker, but more cation-resistant, permeabilization occurred at concentrations that correlated with the inhibition of fungal growth. Rs-AFP2(Y38G), an inactive variant of the plant defensin Rs-AFP2 from Raphanus sativus, failed to induce cation-resistant permeabilization in N. crassa. Dm-AMP1, a plant defensin from Dahlia merckii, induced cation-resistant membrane permeabilization in yeast (Saccharomyces cerevisiae) which correlated with its antifungal activity. However, Dm-AMP1 could not induce cation-resistant permeabilization in the Dm-AMP1-resistant S. cerevisiae mutant DM1, which has a drastically reduced capacity for binding Dm-AMP1. We think that cation-resistant permeabilization is binding site mediated and linked to the primary cause of fungal growth inhibition induced by plant defensins.     

Review of fungal chitinases

Chitin is the second most abundant organic and renewable source in nature, after cellulose. Chitinases are chitin-degrading enzymes. Chitinases have important biophysiological functions and immense potential applications. In recent years, researches on fungal chitinases have made fast progress, especially in molecular levels. Therefore, the present review will focus on recent advances of fungal chitinases, containing their nomenclature and assays, purification and characterization, molecular cloning and expression, family and structure, regulation, and function and application.
