In marine environment, antifouling properties against marine sessile organisms(algae, sea squirts, barnacles, etc.) were tested on various kinds of hydrogels in a longterm. The results demonstrate that most hydrogels can ensure at least 2 months inmarine environment. In particular, mechanically tough PAMPS/PAAm DN and PVAgels exhibited amazing antifouling activity against ma...

Experimentally, paramyxoviruses are conventionally considered good inducers of type I interferons (IFN-alpha/beta), and have been used as agents in the commercial production of human IFN-alpha. However, in the last few years it has become clear that viruses in general mount a major challenge to the IFN system, and paramyxoviruses are no exception. Indeed, most paramyxoviruses encode mechanisms ...

A C-type lectin (CfLec-3) from Chlamys farreri with three carbohydrate-recognition domains (CRDs) was selected to dissect the possible mechanisms of PAMP binding and functional differentiation of invertebrate lectins. CfLec-3 distributed broadly, and its mRNA expression in hemocytes increased significantly after stimulations with LPS, PGN or β-glucan, but not poly(I:C). The recombinant CfLec-3 ...

Human monocyte-derived dendritic cells (DCs) exposed to pathogen-associated molecular patterns (PAMPs) undergo bioenergetic changes that influence the immune response. We found that stimulation with PAMPs enhanced glycolysis in DCs, whereas oxidative phosphorylation remained unaltered. Glucose starvation and the hexokinase inhibitor 2-deoxy-d-glucose (2-DG) modulated cytokine expression in stim...

Staphylococcus aureus is capable of causing a spectrum of human illnesses. During serious S. aureus infections, the staphylococcal pathogen-associated molecular patterns (PAMPs) such as peptidoglycan, lipoteichoic acid, and lipoproteins and even intact S. aureus, are believed to act in conjunction with the staphylococcal superantigens (SSAg) to activate the innate and adaptive immune system, re...

Innate immune activation is initiated by recognition of pathogen associated molecular patterns (PAMPs). Delivery of PAMPs to their respective receptors, regulation of receptor activity, and effector functions downstream from these receptors, which constitute part of the initiated innate immune control, are in part mediated via macroautophagy, an evolutionary conserved pathway for cytoplasmic co...

BACKGROUND Neutrophil elastase plays an important role in the development and progression of acute respiratory distress syndrome (ARDS). Although the selective elastase inhibitor, sivelestat, is widely used in Japan for treating ARDS patients, its effectiveness remains controversial. The aim of the current study was to investigate the effects of sivelestat in ARDS patients with evidence of incr...

The mortality of septic shock in the pediatric population has improved over the last 2 decades with better supportive care however it still remains unacceptably high. Exaggerated inflammatory responses early in septic shock have been associated with poor outcomes. Regulation of the magnitude of the early inflammatory response is not well understood. The earliest aspect of the inflammatory respo...
