    Abstract Macrophages are immune cells that are widespread throughout the body and critical for maintaining tissue homeostasis. Their remarkable plasticity allows them to acquire different phenotypes, becoming able either to fight infection (M1-like, classically activated macrophages) or to promote tissue remodeling and repair (M2-like, alternatively activated macrophages). These phenotypes are induced by different cues present in the microenvironment. Among the factors that might regulate macrophage activation are mediators produced by different branches of the nervous system. The regulation exerted by the sympathetic nervous system (SNS) on macrophages (and the immune system in general) is becoming a subject of increasing interest, indeed a great number of articles have been published lately. Catecholamines (noradrenaline and adrenaline) activate α and β adrenergic receptors expressed by macrophages and shape the effector functions of these cells in contexts as diverse as the small intestine, the lung, or the adipose tissue. Activation of different subsets of receptors seems to produce antagonistic effects, with α adrenergic receptors generally associated with pro-inflammatory functions and β adrenergic receptors (particularly β2) related to the resolution of inflammation and tissue remodeling. However, exceptions to this paradigm have been reported, and the factors contributing to these apparently contradictory observations are still far from being completely understood. Additionally, macrophages

    Abstract Dendritic cells are of paramount importance bridging innate and adaptive immune responses. Depending on the context, after sensing environmental antigens, commensal microorganisms, pathogenic agents, or antigens from the diet, dendritic cells may drive either different effector adaptive immune responses or tolerance, avoiding tissue damage. Although the plasticity of the immune response and the capacity to regulate itself are considered essential to orchestrate appropriate physiological responses, it is known that the nervous system plays a relevant role controlling immune cell function. Dendritic cells present in the skin, the intestine, and lymphoid organs, besides expressing adrenergic receptors, can be reached by neurotransmitters released by sympathetic fibers innervating these tissues. These review focus on how neurotransmitters from the sympathetic nervous system can modulate dendritic cell function and how this may impact the immune response and immune-mediated disorders.

    Abstract The technological, sensory, and nutritional characteristics of meat products are directly related to their animal fat content. Adding animal fat to meat products significantly influences their sensory properties, such as color, taste, and aroma. In addition, the physicochemical properties of fat decisively contribute to the texture of meat products, playing a fundamental role in improving the properties of viscosity, creaminess, chewiness, cohesiveness, and hardness. However, meat products' high animal fat content makes them detrimental to a healthy diet. Therefore, reducing the fat content of meat products is an urgent need, but it is a challenge for researchers and the meat industry. The fat reduction in meat products without compromising the product's quality and with minor impacts on the production costs is not a simple task. Thus, strategies to reduce the fat content of meat products should be studied with caution. During the last decades, several fat replacers were tested, but among all of them, the use of flours and fibers, hydrocolloids, mushrooms, and some animal proteins (such as whey and collagen) presented promising results. Additionally, multiple strategies to gel oils of vegetable origin are also a current topic of study, and these have certain advantages such as their appearance (attempts to imitate animal fat), while also improving the nutritional profile of the lipid fraction of the products meat. However, each of these fat substitutes has both advantages and limitations in their use, which will be discussed in subsequent sections. Therefore, due to the growing interest in this issue, this review focuses on the main substitutes for animal fat used in the production of meat products, offering detailed and updated information on the latest discoveries and advances in this area.

    Abstract Dwarfism is a skeletal disorder that causes abnormal growth. In Miniature horses, dwarfism can occur as chondrodysplastic dwarfism, an autosomal recessive disorder associated with five mutations (D1, D2, D3*, D4 and c.6465A > T variant) in the aggrecan (ACAN) gene. The aim of this study was to evaluate the expression of aggrecan (at the gene and protein level) and specific cytokines (IL-1β, IL-6, and TNF-α) in the articular cartilage of Miniature horses with chondrodysplastic dwarfism (D4/c.6465A > T genotype). Metatarsal bone samples from eight dwarf Miniature horses were collected for histopathological analysis, and articular cartilage was collected to detect and quantify aggrecan levels through Western blotting and determine the relative expression levels of ACAN, IL-1β, IL-6, and TNF-α through qPCR. All affected animals presented chondrodysplasia-like lesions with disorganization of the chondrocyte layers and reduced the amount of an extracellular matrix. No significant difference in aggrecan expression levels in uncleaved samples from the dwarf and control groups (composed of phenotypically normal animals of similar age and breed (P = .7143)) was found using Western blotting. qPCR revealed that ACAN gene expression was higher in the affected animals than in normal animals (P = .0119). No significant difference in cytokine levels was detected between the groups. Mutant aggrecan may interfere with normal cellular function, leading to chondrodysplasia and the observed phenotypic findings.

    Abstract Hereditary myotonia (HM) is characterized by delayed muscle relaxation after contraction as a result of a mutation in the CLCN1 gene. We describe here a complex CLCN1 variant in a mixed-breed dog with clinical and electromyographic signs of HM. Blood samples from the myotonic dog, as well as from his male littermate and parents, were analyzed via amplification of the 23 exons encoding CLCN1. After sequencing the CLCN1 gene, a complex variant was found in exon 6 c.[705T>G; 708del; 712_732del], resulting in a premature stop codon in exon 7 and a protein that was 717 amino acids shorter than the normal CLC protein. The myotonic dog was identified as homozygous recessive for the complex CLCN1 variant; its parents were heterozygous, and its male littermate was homozygous wild-type. Knowledge of the CLCN1 mutations responsible for the development of hereditary myotonia allows greater clarification of this condition.

    Abstract Although several studies demonstrate that stressful situations, such as sleep disturbances, negatively impact the innate and adaptive arms of the immune system, their influence on invariant Natural Killer T (iNKT) cells remains unclear. iNKT cells are CD1d-restricted innate T cells that recognize glycolipid antigens and rapidly produce polarizing cytokines being key players in several immune responses, and a potential target for immunotherapy. iNKT cells differ in several aspects from conventional T lymphocytes, including a unique dependence on CD1d-expressing double-positive (DP) thymocytes for intrathymic maturation. As a consequence of stress, DP thymocytes undergo glucocorticoid-induced apoptosis, which might compromise iNKT developmental pathway. Therefore, we used a paradoxical sleep deprivation (SD) model to determine the impact of sleep disturbance on iNKT cell biology. After 72 h of SD, C57Bl/6 mice exhibited a significant increase in systemic glucocorticoid levels and thymus atrophy. Despite marked decrease in the number of DP thymocytes, the ratio CD1d

    Abstract ABSTRACT: The present study investigated Salmonella spp. in the feces of 200 foals up to one year of age (100 with clinical signs of diarrhea and 100 without clinical signs of diarrhea). Bacteriological culture, serotyping, antimicrobial susceptibility, and real-time PCR (qPCR SYBR® Green or a TaqMan®) for detecting the invA gene (with and without a selective pre-enrichment step in tetrathionate broth) were performed. Bacterial culture revealed 15% (n=30) of positive animals (21 animals with diarrhea and nine without diarrhea). Among the 30 isolates, 13 different serovars were identified: S. Infantis, S. Minnesota, S. I.4,5,12:i:-; S. Anatum, S. Cerro, S. Oranienburg, S. Braenderup, S. Give, S. Newport, S. IIIb 61:c:z35, S. 109:-:1.5, S. I.4.12:d:-, S. I.6.8:-:-. Multidrug resistance was found in 43.33% (n=13) of the isolates, with one isolate obtained from animals without diarrhea and 12 isolates from animals with diarrhea. All qPCR techniques used in the study classified more samples as positive for Salmonella spp. than the bacterial culture of feces. In addition, all qPCR techniques detected more positive animals in the diarrhea group than in the diarrhea-free group. The results confirm the utility of the qPCR method without the pre-enrichment step in tetrathionate as a rapid test for Salmonella spp. in carrier animals. In animals with clinical signs of diarrhea, it can be combined with bacterial culture (antimicrobial susceptibility testing and serotyping). The isolation of Salmonella spp. in nine animals without diarrhea confirms the importance of asymptomatic carrier animals in the epidemiology of the disease. The multidrug resistance observed highlights the importance of rational antimicrobial use in horses and adopting biosecurity protocols that are efficacious in controlling the spread of infections between animals and zoonotic transmission in farms.
