Recombinant ferritin-H induces immunosuppression in European sea bass larvae (Dicentrarchus labrax) rather than immunostimulation and protection against a Vibrio anguillarum infection
In this study, we evaluated if the recombinant sea bass ferritin-H could stimulate the innate immune system of gnotobiotic European sea bass larvae resulting in protection against a V. anguillarum challenge. We also evaluated the effect of a V. anguillarum infection on the transcription of immune-related genes in gnotobiotic European sea bass larvae. Recombinant sea bass ferritin-H was produced, encapsulated in calcium alginate microparticles and orally delivered to sea bass larvae at seven days after hatching. Our results showed V. anguillarum caused an acute infection, resulting in high mortality. The infection significa...

C-C motif chemokine ligand (CCL) production in equine peripheral blood mononuclear cells identified by newly generated monoclonal antibodies
Publication date: Available online 11 September 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Christiane L. Schnabel, Michelle Wemette, Susanna Babasyan, Heather Freer, Cynthia Baldwin, Bettina WagnerAbstractChemokines are soluble molecules directing immune cell trafficking and homing, mediating inflammation, and initiating immune responses to infection. In horses, the analysis of chemokines has been limited by the lack of specific antibodies. We generated mAbs specific for the equine C-C motif chemokine ligands (CCL) CCL2 (MCP-1), CCL3 (MIP-1α), CCL5 (RANTES) and CCL11 (eotaxin) using hybridoma tec...

Antibody-mediated bacterial killing of Ichthyobacterium seriolicida in Japanese amberjack
In this study, fish were passively immunized to determine whether serum antibody is involved in protection against BHJ. The susceptibility of I. seriolicida to the bactericidal activity of Japanese amberjack serum was also investigated. In passive immunization tests, significantly lower mortality was noted in fish that received convalescent serum. Bacteria were killed when exposed to convalescent serum but not serum from naïve fish. Electron microscopic analyses showed that I. seriolicida cells were morphologically altered by reaction with convalescent serum. Naïve fish serum became bactericidal upon addition of ...

Enhancing purification and plasma stability of porcine interferon-α/γ by fusion to elastin-like polypeptide
In this study, we evaluated the feasibility of ELP fusion for simple purification and half-life extension of recombinant porcine IFNs (rPoIFNs). After construction of five different fusion expression vectors, we optimized the conditions for soluble protein expression and purification. SDS-PAGE analysis showed that, unlike PoIFNα-His and PoIFNγ-His, PoIFNα-ELP, ELP-PoIFNα and PoIFNαγ-ELP were expressed mainly as soluble proteins at 20 ℃. The optimal conditions for the inverse transition cycling (ITC) of three ELP fusion proteins were 2 M NaCl at 28 ℃. After two rounds of ITC, t...

Resveratrol administration increases phagocytosis, decreases oxidative burst, and promotes pro-inflammatory cytokine production in healthy dogs
The objective of this study was to determine the short-term effect of resveratrol on the healthy canine innate immune system in vivo. The hypothesis was that resveratrol would spare phagocytosis, depress the vigor of PMN oxidative burst, and result in a proinflammatory stimulated leukocyte cytokine profile in vivo. In an open-label study, whole blood was collected from 12 healthy, adult client-owned dogs on day 0 and 3. Six dogs received resveratrol, 200 mg kg-1, orally once daily for three days and six dogs served as controls with no supplement administered. Phagocytosis, oxidative burst and pathogen associa...

In this study, the immunogenicity and protective capacity of a new recombinant vaccine candidate, the rFh14-3-3z protein was analysed in sheep experimentally challenged with Fasciola hepatica, in terms of fluke burden, faecal egg counts, hepatic damage and humoral immune response. Three groups of 8 animals each were used for study, group 1 was immunised with the rFh14-3-3z in Montanide adjuvant, whereas group 2 and 3 remained as adjuvant control and infection control groups, respectively. The parasitological analysis showed that no significant reduction in fluke burden, fluke size and faecal egg counts was detected. The ex...

CIRCULATING REGULATORY T CELLS (Treg), LEPTIN AND INDUCTION OF PROINFLAMMATORY ACTIVITY IN OBESE LABRADOR RETRIEVER DOGS
Publication date: Available online 7 July 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Anna Teresa Palatucci, Diego Piantedosi, Valentina Rubino, Angela Giovazzino, Jacopo Guccione, Vlenia Pernice, Giuseppina Ruggiero, Laura Cortese, Giuseppe TerrazzanoAbstractOver-nutrition and obesity have been associated with impaired immunity and low-grade inflammation in humans and mouse models. In this context, a causal role for unbalanced T regulatory cell (Treg)-dependent mechanisms has been largely suggested.Obesity is the most common nutritional disorder in dogs. However, it is not defined whether canine obesit...

Beneficial and detrimental impact of transplanted canine adipose-derived stem cells in a virus-induced demyelinating mouse model
Publication date: Available online 8 July 2018Source: Veterinary Immunology and ImmunopathologyAuthor(s): Florian Hansmann, Nicole Jungwirth, Ning Zhang, Thomas Skripuletz, Veronika Maria Stein, Andrea Tipold, Martin Stangel, Wolfgang BaumgärtnerAbstractIn recent years stem cell therapies have been broadly applied in various disease models specifically immune mediated and degenerative diseases. Whether adipose-derived stem cells might represent a useful therapeutic option in virus-triggered central nervous system diseases has not been investigated so far. Theiler’s murine encephalomyelitis (TME) and canine diste...

Assessment of Poly(ADP-ribose) Polymerase1 (PARP1) expression and activity in cells purified from blood and milk of dairy cattle
In conclusion, these findings suggest that PARP1 is activated during mastitis, which may prove to be a useful biomarker of mastitis. (Source: Veterinary Immunology and Immunopathology)

Expression of pattern recognition receptors in porcine uterine epithelial cells in vivo and in culture
Publication date: August 2018Source: Veterinary Immunology and Immunopathology, Volume 202Author(s): Glenn Hamonic, J. Alex Pasternak, Nikki M. Forsberg, Tobias Käser, Heather L. WilsonAbstractPreservation of a pathogen free uterine environment is critical for maintaining healthy swine herds with high reproductive performance. Considering that uterine epithelial cells are the most numerous and thus likely point of cellular contact for pathogens in the uterus, we hypothesize that these cells may be critical for activating the immune system to clear uterine infections. Although uterine epithelial cells have not been wel...
