Role of nasal microbiota in regulating host anti-influenza immunity in dogs.

Microbiome

January 2025

Joint International Research Laboratory of Animal Health and Food Safety, College of Veterinary Medicine, Nanjing Agricultural University, Nanjing, China.

Background: Numerous studies have confirmed a close relationship between the pathogenicity of influenza and respiratory microbiota, but the mechanistic basis for this is poorly defined. Also, the majority of these studies have been conducted on murine models, and it remains unclear how far these findings can be extrapolated from murine models to other animals. Considering that influenza A virus is increasingly recognized as an important canine respiratory pathogen, this study investigated the cross-talk between nasal and lung tissues mediated by microbes and its association with influenza susceptibility in a beagle dog model.

Use of D-Squame as a Minimally Invasive Technique to Evaluate Skin Immune Response Biomarkers in Canine Atopic Dermatitis.

Vet Sci

December 2024

Interactions Cells Environment, 2016. A104, VetAgro Sup, Dermatology Department, 69280 Marcy L'étoile, France.

Evaluation of skin inflammation biomarkers in canine atopic dermatitis (AD) currently requires skin biopsies. Tape stripping has been shown to be a reliable technique to study biomarkers in the stratum corneum (SC) in humans. The aim of this study was to assess the immune response and identify biomarkers in the SC of dogs with canine AD using D-squame as a minimally invasive technique.

Objective: To evaluate the sparing effects of fentanyl and maropitant on sevoflurane minimum alveolar concentrations that block autonomic responses (MACBAR) and the hemodynamic and electroencephalographic responses to noxious stimuli in dogs.

Methods: The sevoflurane MACBAR was determined in 5 healthy male Beagles with or without continuous infusions of fentanyl and maropitant. Then, intermittent noxious stimulation was applied at 1.

Breed differences in olfactory performance of dogs.

Sci Rep

January 2025

HUN-REN-ELTE Comparative Ethology Research Group, Budapest, Hungary.

Most studies on dogs' olfactory performance focused only on some individuals pre-trained for a task or on specially selected/trained detection dogs. Here, using the Natural Detection Task (NDT) that does not require training, we assessed the effect of several potential factors on the performance of a large sample of dogs (N = 527/tested, 484/analysed). Olfactory success was associated with breeds, but breed groups (selected for olfaction, cooperation, or both) were proven non-relevant, suggesting that breed-specific traits are more influential than functional breed group characteristics.

Background: Dupilumab has been added to National Cancer Comprehensive Network (NCCN) guidelines as a therapeutic strategy for managing certain cutaneous immune-related adverse events (cirAEs) from immune checkpoint inhibitor (ICI) therapy. However, little is known about the implications of dupilumab for cancer outcomes in this population. In this multi-institutional study, we evaluate the impact of dupilumab treatment on survival among ICI recipients.
