Plain-English summary
A 1- to 2-year-old dog with generalized demodicosis, a skin condition caused by mites, had higher levels of a protein called insulin-like growth factor-2 (IGF-2) in both its blood and skin compared to healthy dogs. This suggests that the skin cells in affected dogs are producing more IGF-2, which may play a role in the condition. Understanding these changes could help veterinarians develop better treatments for dogs suffering from this skin problem.

Abstract
BACKGROUND: There is increasing evidence that insulin-like growth factor-2 (IGF-2) levels are altered in skin injury; there are no data evaluating the serum concentration and skin tissue expression of IGF-2 in canine generalized demodicosis. HYPOTHESIS/OBJECTIVES: To assess serum concentrations of IGF-2 collected from dogs with generalized demodicosis compared to healthy dogs and to determine the location of IGF-2 in the skin of affected dogs. METHODS: Blood and skin samples were collected from 12 dogs of differing breeds and gender at 1-2 years of age that had a confirmed diagnosis of generalized demodicosis. Age-matched control skin and blood samples were collected from 11 normal dogs of different breeds and gender. Serum IGF-2 concentrations were measured by enzyme-linked immunosorbent assay. Skin tissue expression of IGF-2 was analysed by immunohistochemical methods. RESULTS: Serum concentration and skin tissue expression of IGF-2 were increased in dogs with generalized demodicosis compared with control dogs. CONCLUSIONS AND CLINICAL IMPORTANCE: These findings indicate that keratinocytes, histiocytes and fibrocytes in the dermis are positive for IGF-2; they may be a source of the elevated serum IGF-2 levels in dogs with generalized demodicosis.
