    Abstract Background: Atopic dermatitis (AD) is a common inflammatory skin disease of dogs. Interleukin (IL)-34 is a monocyte/macrophage growth factor, produced mainly by keratinocytes, that has been implicated in several human inflammatory conditions including human AD.
    Hypothesis: Canine serum IL-34 concentrations are increased in dogs with AD and correlate with clinical lesion and pruritus scores.
    Animals: Forty seven client-owned dogs diagnosed with AD and 25 healthy, unaffected control dogs.
    Methods and materials: A commercially available IL-34 ELISA was optimized for the measurement of IL-34 in canine serum samples. Information regarding treatment, clinical lesion scores [Canine Atopic Dermatitis Extent and Severity Index, 4th iteration (CADESI-04)] and pruritus Visual Analog Score (pVAS) were recorded for each dog at the time of serum collection.
    Results: Dogs with AD had significantly increased serum IL-34 concentrations compared to controls. There was a significant positive correlation between IL-34 concentrations and CADESI-04 and pVAS scores. Concentrations of IL-34 remained increased in dogs with AD receiving steroids or the JAK1 inhibitor, oclacitinib, compared to unaffected control dogs.
    Conclusions and clinical importance: Serum IL-34 concentrations are increased in dogs with AD and are correlated with clinical severity and pruritus. IL-34 may be a suitable candidate therapeutic target for canine AD.

    Abstract With research to suggest that urban greenspace use can affect the health and wellbeing of adults, it is important to investigate this association in children. Compared with factors such as physical activity, research considering greenspace and its association with the health and wellbeing of children from urban areas is relatively rare. This study examined the health-related quality of life of 276 children residing in the city of Edinburgh in relation to quantity and use of greenspace. As much of the existing research has employed parental reports of children's health, the current study assessed health-related quality of life via self-report, measured using the Kid-KINDL questionnaire (Ravens-Sieberer & Bullinger, 1998). Spatial analysis of greenspace quantity and typology was undertaken using mapping software, ArcGIS (Esri, 2011). In regression analysis, higher greenspace use and having fewer siblings were significantly associated with better health-related quality of life. Further analysis revealed that these variables were also associated with the 'friends' sub-scale score of the Kid-KINDL. Higher greenspace use was positively associated with 'self-esteem' sub-scale scores. However, the quantity of residential greenspace was not associated with the health-related quality of life of children. This study suggests that increased use of greenspace in urban areas might have a small but positive impact on child health-related quality of life, though future longitudinal and intervention studies are required to confirm these causal assumptions.

    Abstract Growth hormone controls somatic growth in mammals by regulating the production of IGF-1, which is predominantly made by the liver. The development of cells within the MPS is controlled by the lineage-specific growth factor M-CSF (CSF-1). In this review, we summarize the role of CSF-1-dependent macrophages in somatic growth and organogenesis. We propose that macrophages are the major extrahepatic source of IGF-1 and that a surge of CSF-1 production contributes to the control of postnatal growth and organ maturation. Accordingly, CSF-1 may be considered a part of the GH/IGF-1 axis.

    Abstract Faecal samples were collected from 57 clinically healthy kittens presented for initial vaccination, in the UK. Routine bacteriological examination identified Salmonella species in one and Campylobacter species in five samples. Polymerase chain reaction (PCR) detected the presence of Campylobacter species in a further four samples. Routine parasitological examination revealed Toxocara species ova in nine (including four kittens stated to have been administered an anthelmintic) and Isospora species in four samples. No Giardia or Cryptosporidium species were detected by routine methods. A Giardia species enzyme-linked immunosorbent assay (ELISA) test kit designed for use in cats was positive in three kittens. A similar test kit designed for use in humans was negative in all samples and produced negative results even when known positive samples were tested. Potentially pathogenic enteric organisms were detected in 19 kittens by routine methods and 26 (prevalence 45%) by all methods. The high prevalence in asymptomatic kittens highlights the possibility that the detection of these organisms in kittens with gastrointestinal disease may be an incidental finding.

    Abstract Colony stimulating factor (CSF-1) and its receptor, CSF-1R, have been previously well studied in humans and rodents to dissect the role they play in development of cells of the mononuclear phagocyte system. A second ligand for the CSF-1R, IL-34 has been described in several species. In this study, we have cloned and expressed the feline CSF-1R and examined the responsiveness to CSF-1 and IL-34 from a range of species. The results indicate that pig and human CSF-1 and human IL-34 are equally effective in cats, where both mouse CSF-1 and IL-34 are significantly less active. Recombinant human CSF-1 can be used to generate populations of feline bone marrow and monocyte derived macrophages that can be used to further dissect macrophage-specific gene expression in this species, and to compare it to data derived from mouse, human and pig. These results set the scene for therapeutic use of CSF-1 and IL-34 in cats.

    Abstract Macrophage Colony Stimulating Factor (CSF-1) controls the survival, differentiation and proliferation of cells of the mononuclear phagocyte system. A second ligand for the CSF-1R, Interleukin 34 (IL-34), has been described, but its physiological role is not yet known. The domestic pig provides an alternative to traditional rodent models for evaluating potential therapeutic applications of CSF-1R agonists and antagonists. To enable such studies, we cloned and expressed active pig CSF-1. To provide a bioassay, pig CSF-1R was expressed in the factor-dependent Ba/F3 cell line. On this transfected cell line, recombinant porcine CSF-1 and human CSF-1 had identical activity. Mouse CSF-1 does not interact with the human CSF-1 receptor but was active on pig. By contrast, porcine CSF-1 was active on mouse, human, cat and dog cells. IL-34 was previously shown to be species-specific, with mouse and human proteins demonstrating limited cross-species activity. The pig CSF-1R was equally responsive to both mouse and human IL-34. Based upon the published crystal structures of CSF-1/CSF-1R and IL34/CSF-1R complexes, we discuss the molecular basis for the species specificity.
