Males and females exhibit profound differences in immune responses and disease susceptibility. However, the factors responsible for sex differences in tissue immunity remain poorly understood. Here, we uncovered a dominant role for type 2 innate lymphoid cells (ILC2s) in shaping sexual immune dimorphism within the skin. Mechanistically, negative regulation of ILC2s by androgens leads to a reductio
The development of vaccines based on outer membrane vesicles (OMV) that naturally bud off from bacteria is an evolving field in infectious diseases. However, the inherent inflammatory nature of OMV limits their use as human vaccines. This study employed an engineered vesicle technology to develop synthetic bacterial vesicles (SyBV) that activate the immune system without the severe immunotoxicity
Tissue immunity and responses to injury depend on the coordinated action and communication among physiological systems. Here, we show that, upon injury, adaptive responses to the microbiota directly promote sensory neuron regeneration. At homeostasis, tissue-resident commensal-specific T cells colocalize with sensory nerve fibers within the dermis, express a transcriptional program associated with
Bacterial outer membrane vesicles (OMV) have gained attention as a promising new cancer vaccine platform for efficiently provoking immune responses. However, OMV induce severe toxicity by activating the innate immune system. In this study, we applied a simple isolation approach to produce artificial OMV that we have named Synthetic Bacterial Vesicles (SyBV) that do not induce a severe toxic respon
This is a proof-of-principle study demonstrating that the combination of a cholera toxin derived adjuvant, CTA1-DD, and lipid nanoparticles (LNP) can significantly improve the immunogenicity and protective capacity of an intranasal vaccine. We explored the self-adjuvanted universal influenza vaccine candidate, CTA1-3M2e-DD (FPM2e), linked to LNPs. We found that the combined vector greatly enhanced
Vaccination of neonates and young infants is hampered by the relative immaturity of their immune systems and the lack of safe and efficacious vaccine adjuvants. Immaturity of the follicular dendritic cells (FDCs), in particular, appears to play a critical role for the inability to stimulate immune responses. Using the CD21mT/mG mouse model we found that at 7 days of life, FDCs exhibited a mature p
BACKGROUND: Sepsis remains a source of high mortality in hospitalized patients despite proper antibiotic approaches. Encouragingly, mesenchymal stromal cells (MSCs) and their produced extracellular vesicles (EVs) have been shown to elicit anti-inflammatory effects in multiple inflammatory conditions including sepsis. However, EVs are generally released from mammalian cells in relatively low amount
Adjuvanted whole inactivated virus (WIV) influenza vaccines show promise as broadly protective influenza vaccine candidates. Using WIV as basis we assessed the relative efficacy of different adjuvants by carrying out a head-to-head comparison of the liposome-based adjuvants CAF01 and CAF09 and the protein-based adjuvants CTA1-DD and CTA1-3M2e-DD and evaluated whether one or more of the adjuvants c
While numerous extraction methods have been applied to the brown algae Saccharina latissima, a systematic evaluation of how individual extraction parameters influence the extraction of each target polysaccharide has not previously been reported. Accordingly, this study compared conventional and advanced techniques for extracting fucoidan, laminarin, and alginate from pre-treated biomass. Conventio
This invention relates to methods for purification of paclitaxel from a paclitaxel-containing material. The method comprises the following steps: (a) extracting a paclitaxel-containing material with an organic solvent to obtain an extract, and concentrating the extract; (b) adding the concentrate with an organic solvent which is not mixed with water to separate an organic solvent phase and then co
Disclosed is a process for production of a cycloaliphatic carbonate from a diol, triol or polyol and a carbon dioxide source, such as a dialkyl carbonate. Said process is performed in a solvent-free medium using a N-heterocyclic carbene or N-heterocyclic carbene complex as catalyst. Said N-heterocyclic carbene or carbene complex is preferably attached to a lipase. Said process comprises preferably
Audio Paper offers a conceptual and practice-based approach for researchers across a wide range of disciplines to integrate auditory culture into their published work in the form of the audio paper.The audio paper is an academic text presented as an audio production. Introducing this new format, the book invites scholars to work in a publication format that integrates aesthetic perspectives and te
Recent studies provide compelling evidence that transition dynamics differ between sectors. This paper develops a theoretical framework for analysing the structural composition of a sector and how it shapes transition dynamics. We elaborate a conceptual approach, which emphasizes socio-technical configurations and their degrees of institutionalization and mutual alignment as the key building block
Background: The out-of-plane shear behavior of paperboards plays a critical role in converting processes such as creasing and folding. The recently proposed Split Double Cantilever Beam (SDCB) specimen has been used to characterize this behavior using a cohesive zone model, but its large size poses handling challenges. Objective: This study aims to optimize the SDCB specimen configuration to impro
Adverse childhood experiences (ACEs) can influence physical, cognitive and social development, impacting life outcomes including the child’s capacity to learn and become socially integrated. While steady relations to reliable, understanding adults may enhance child resilience and mitigate long-term effects on well-being, the difficulties of children with ACEs pose a challenge for school personnel.
Purpose: Indications for radiotherapy (RT) of the internal mammary nodes (IMN) in early breast cancer vary between countries. While studies indicate benefits, IMN RT increases the dose to the heart and lungs, and the risk-benefit ratio of this treatment is debated. This study investigates how IMN RT affects dose to organs at risk (OAR) and pneumonitis incidence in a clinical setting. Methods: This
The standard approach for visual place recognition is to use global image descriptors to retrieve the most similar database images for a given query image. The results can then be further improved with re-ranking methods that re-order the top scoring images. However, existing methods focus on re-ranking based on the same image descriptors that were used for the initial retrieval, which we argue pr
The performance of wireless communications at sea are often limited by fading caused by reflections at the sea surface. The reliability could potentially be improved by employing multiple antennas. We have conducted massive multiple-input multiple-output (MIMO) measurements at sea in order to evaluate the performance. The measurements were conducted at 5.6 GHz with 64 dual-polarized antennas, whic
—Capacitor chargers for pulsed power loads are typically realized as two-stage systems consisting of a front-end rectifier and a dclink filter followed by a dc/dc converter. Whereas such systems generally operate in constant current charging mode, it has recently been demonstrated that constant power charging may be achieved and can effectively eliminate line-side flicker. In this article, these i
