Using the Key Characteristics Framework to Unlock the Mysteries of Aryl Hydrocarbon Receptor-Mediated Effects on the Immune System.

Initially discovered for its role mediating the deleterious effects of environmental contaminants, the aryl hydrocarbon receptor (AHR) is now known to be a crucial regulator of the immune system. The expanding list of AHR ligands includes synthetic and naturally derived molecules spanning pollutants, phytochemicals, pharmaceuticals, and substances derived from amino acids and microorganisms. The consequences of engaging AHR vary, depending on factors such as the AHR ligand, cell type, immune challenge, developmental state, dose, and timing of exposure relative to the immune stimulus.

ALC-0315 Lipid-Based mRNA LNP Induces Stronger Cellular Immune Responses Postvaccination.

Methods: Through stakeholder development workshops, literature reviews, surveys and public consultation, we developed an aspirational MDS. We identified ways to extract this from existing sources, including DCRs and routine health and social care datasets.

Failure of colonization following gut microbiota transfer exacerbates DSS-induced colitis.

To study the impact of differing specific pathogen-free gut microbiomes (GMs) on a murine model of inflammatory bowel disease, selected GMs were transferred using embryo transfer (ET), cross-fostering (CF), and co-housing (CH). Prior work showed that the GM transfer method and the microbial composition of donor and recipient GMs can influence microbial colonization and disease phenotypes in dextran sodium sulfate-induced colitis. When a low richness GM was transferred to a recipient with a high richness GM via CH, the donor GM failed to successfully colonize, and a more severe disease phenotype resulted when compared to ET or CF, where colonization was successful.

Effects of community action on animal vaccination uptake, antimicrobial usage, and farmers' wellbeing in Ghana: study protocol for a cluster-randomized controlled trial.

Infectious animal diseases represent a major constraint to livestock productivity, food security and wellbeing in many developing countries. To mitigate these impacts, farmers frequently use antimicrobials without professional advice, potentially yielding drug residues in livestock products and the food chain, as well as resistant antimicrobial genes. Recent studies identified Contagious Bovine Pleuropneumonia (CBPP) and Peste des Petits Ruminants (PPR) as the diseases most negatively affecting ruminant livestock productivity and farmers' wellbeing in Ghana.

Multiplex one-step RT‒qPCR assays for simultaneous detection of AMDV, MEV and CDV.

Background: Aleutian mink disease, mink viral enteritis and canine distemper are known as the three most serious diseases that cause great economic loss in the mink industry. In clinical practice, aleutian mink disease virus (AMDV), mink enteritis virus (MEV) and canine distemper virus (CDV) are common mixed infections, and they have similar clinical clinical signs, such as diarrhoea. Therefore, a rapid and accurate differential diagnosis method for use on mink ranches is essential for the control of these three pathogens.

Effects of injectable trace minerals (Se, Zn, Cu, and Mn) administration on the immune response elicited by primary intranasal modified-live virus vaccination in dairy calves.

The objective was to determine the effects of injectable trace minerals (ITM, containing Se, Cu, Zn & Mn) administered at the time of primary intranasal (IN) modified-live virus (MLV) vaccination of young dairy calves on the serum neutralizing antibody (SNA) titers to Bovine herpes virus 1 (BHV1), Bovine respiratory syncytial virus (BRSV), and Bovine Parainfluenza type 3 virus (BPIV); cytokine expression in peripheral white blood cells, and BHV1-specific IgA titers in nasal secretions following the vaccination. A total of 60 calves (1 month old) were administered an IN MLV vaccine containing BHV1, BRSV, BPIV (Inforce 3) and randomly assigned to one of two experimental groups: ITM (n = 30; Multimin90, containing Se, Cu, Zn, and Mn) or SAL (n = 30; sterile saline). There was a consistent decay in virus-specific SNA titers in both groups.

GGCX promotes Eurasian avian-like H1N1 swine influenza virus adaption to interspecies receptor binding.

The Eurasian avian-like (EA) H1N1 swine influenza virus (SIV) possesses the capacity to instigate the next influenza pandemic, owing to its heightened affinity for the human-type α-2,6 sialic acid (SA) receptor. Nevertheless, the molecular mechanisms underlying the switch in receptor binding preferences of EA H1N1 SIV remain elusive. In this study, we conduct a comprehensive genome-wide CRISPR/Cas9 knockout screen utilizing EA H1N1 SIV in porcine kidney cells.

A diagnostic host-specific transcriptome response for Mycoplasma pneumoniae pneumonia to guide pediatric patient treatment.
