Metabolic dependent and independent pH-drop shuts down VirSR quorum sensing in Clostridium perfringens.

J Biosci Bioeng

May 2018

Laboratory of Microbial Technology, Faculty of Agriculture, Graduate School, Kyushu University, Fukuoka 812-8581, Japan. Electronic address:

Clostridium perfringens produces various exotoxins and enzymes that cause food poisoning and gas gangrene. The genes involved in virulence are regulated by the agr-like quorum sensing (QS) system, which consists of a QS signal synthesis system and a VirSR two-component regulatory system (VirSR TCS) which is a global regulatory system composed of signal sensor kinase (VirS) and response regulator (VirR). We found that the perfringolysin O gene (pfoA) was transiently expressed during mid-log phase of bacterial growth; its expression was rapidly shut down thereafter, suggesting the existence of a self-quorum quenching (sQQ) system.

Endothelial progenitor cell (EPC) nomenclature remains ambiguous and there is a general lack of concordance in the stem cell field with many distinct cell subtypes continually grouped under the term "EPC." It would be highly advantageous to agree on standards to confirm an endothelial progenitor phenotype and this should include detailed immunophenotyping, potency assays, and clear separation from hematopoietic angiogenic cells which are not endothelial progenitors. In this review, we seek to discourage the indiscriminate use of "EPCs," and instead propose precise terminology based on defining cellular phenotype and function.

Sperm length variations in five species of cypridoidean non-marine ostracods (Crustacea).

Cell Tissue Res

November 2016

College of Science and Engineering, School of Natural System, University of Kanazawa, Kakuma, Kanazawa, 920-1192, Japan.

Spermatozoa of the ostracod superfamily Cypridoidea include some of the longest in the animal kingdom, but unlike other so-called giant spermatozoa, they are aflagellate, probably evolved only once, and represent an exceptionally old trait. Sperm length variations within cypridoidean species remain poorly known, a lack that hinders the development of hypotheses to explain their length and variation. For this study, the lengths of 500 spermatozoa from each of five species of freshwater cypridoidean ostracods, Candonopsis tenuis (Brady, 1886), Fabaeformiscandona subacuta (Yang, 1982), Heterocypris rotundata (Bronshtein, 1928), Ilyocypris japonica Okubo, 1990, and Notodromas trulla Smith and Kamiya, 2014, were measured, including the lengths of the posterior and anterior regions.

Rationale design of quorum-quenching peptides that target the VirSR system of Clostridium perfringens.

FEMS Microbiol Lett

November 2015

Laboratory of Microbial Technology, Department of Biochemistry and Biotechnology, Faculty of Agriculture, Graduate School, Kyushu University, Fukuoka 812-8581, Japan

Article Synopsis
  • - In Clostridium perfringens, a specific 5-membered thiolactone peptide (AIPCp) activates a signal system (VirSR) that regulates the production of various toxins, including alpha, theta, and kappa toxins.
  • - Researchers designed new peptides aimed at disrupting this signaling process (quorum-quenching peptides) using data on how AIPCp works, focusing on key amino acids involved in receptor interaction.
  • - The two newly created peptides, Z-AIPCp-L2A/T5A (a partial agonist) and Z-AIPCp-F4A/T5S (a partial antagonist), effectively reduced the production of the theta toxin gene (pfoA) in a harmful strain

Cyclodepsipeptides produced by actinomycetes inhibit cyclic-peptide-mediated quorum sensing in Gram-positive bacteria.

FEMS Microbiol Lett

July 2015

Laboratory of Microbial Technology, Division of Applied Molecular Microbiology and Biomass Chemistry, Department of Bioscience and Biotechnology, Faculty of Agriculture, Graduate School, Kyushu University, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581, Japan

Cyclic peptides are commonly used as quorum-sensing autoinducers in Gram-positive Firmicutes bacteria. Well-studied examples of such molecules are thiolactone and lactone, used to regulate the expression of a series of virulence genes in the agr system of Staphylococcus aureus and the fsr system of Enterococcus faecalis, respectively. Three cyclodepsipeptides WS9326A, WS9326B and cochinmicin II/III were identified as a result of screening actinomycetes culture extracts for activity against the agr/fsr system.

In adult visual system, goldfish can regrow their axons and fully restore their visual function even after optic nerve transection. The optic nerve regeneration process in goldfish is very long and it takes about a half year to fully recover visual function via synaptic refinement. Therefore, we investigated time course of growth-associated protein 43 (GAP43) expression in the goldfish retina for over 6 months after axotomy.

Purpurin, a retina-specific protein, is known to play a role in cell adhesion during development of the chicken retina. Although purpurin has been significantly detected in adult chicken retina, its function in the matured retina is not well understood. Therefore, to determine the expression pattern of purpurin in the retina, we simultaneously investigated expression patterns of purpurin in the zebrafish retina during development in larvae and optic nerve regeneration after nerve transection in adults.
