- Heat treatment improves antigen-specific T cell activation after protein delivery by several but not all yeast genera.
- Bazan SB1, Breinig T2, Schmitt MJ1, Breinig F3.Author information 1Molecular and Cell Biology, Saarland University, 66123 Saarbrücken, Germany.2Junior Research Group for Virology/Immunology, Department of Virology, Saarland University Hospital, 66421 Homburg, Germany.3Molecular and Cell Biology, Saarland University, 66123 Saarbrücken, Germany. Electronic address: fb@microbiol.uni-sb.de.AbstractA central prerequisite in using yeast as antigen carrier in vaccination is its efficient interaction with cellular components of the innate immune system, mainly mediated by cell surface structures. Here, we investigated the distribution of major yeast cell wall components such as mannan, β-glucan and chitin of four different and likewise biotechnologically relevant yeasts (Saccharomyces, Pichia, Kluyveromyces and Schizosaccharomyces) and analyzed the influence of heat-treatment on β-1,3-glucan exposure at the outer yeast cell surface as well as the amount of yeast induced reactive oxygen species (ROS) production by antigen presenting cells (APC) in human blood. We found that yeasts significantly differ in the distribution of their cell wall components and that heat-treatment affected both, cell wall composition and yeast-induced ROS production by human APCs. We further show that heat-treatment modulates the activation of antigen specific memory T cells after yeast-mediated protein delivery in different ways and thus provide additional support of using yeast as vehicle for the development of novel T cell vaccines.

- Transcription factors that directly regulate the expression of CSLA9 encoding mannan synthase in Arabidopsis thaliana.
- Kim WC1, Reca IB, Kim Y, Park S, Thomashow MF, Keegstra K, Han KH.Author information 1Department of Horticulture, Michigan State University, 126 Natural Resources, East Lansing, MI, 48824-1222, USA.AbstractMannans are hemicellulosic polysaccharides that have a structural role and serve as storage reserves during plant growth and development. Previous studies led to the conclusion that mannan synthase enzymes in several plant species are encoded by members of the cellulose synthase-like A (CSLA) gene family. Arabidopsis has nine members of the CSLA gene family. Earlier work has shown that CSLA9 is responsible for the majority of glucomannan synthesis in both primary and secondary cell walls of Arabidopsis inflorescence stems. Little is known about how expression of the CLSA9 gene is regulated. Sequence analysis of the CSLA9 promoter region revealed the presence of multiple copies of a cis-regulatory motif (M46RE) recognized by transcription factor MYB46, leading to the hypothesis that MYB46 (At5g12870) is a direct regulator of the mannan synthase CLSA9. We obtained several lines of experimental evidence in support of this hypothesis. First, the expression of CSLA9 was substantially upregulated by MYB46 overexpression. Second, electrophoretic mobility shift assay (EMSA) was used to demonstrate the direct binding of MYB46 to the promoter of CSLA9 in vitro. This interaction was further confirmed in vivo by a chromatin immunoprecipitation assay. Finally, over-expression of MYB46 resulted in a significant increase in mannan content. Considering the multifaceted nature of MYB46-mediated transcriptional regulation of secondary wall biosynthesis, we reasoned that additional transcription factors are involved in the CSLA9 regulation. This hypothesis was tested by carrying out yeast-one hybrid screening, which identified ANAC041 and bZIP1 as direct regulators of CSLA9. Transcriptional activation assays and EMSA were used to confirm the yeast-one hybrid results. Taken together, we report that transcription factors ANAC041, bZIP1 and MYB46 directly regulate the expression of CSLA9.
