Equine sweating and anhidrosis Part 2: anhidrosis.

This research article explores anhidrosis, a condition in horses that is possibly triggered by prolonged exposure to stressful climatic conditions. The study provides evidence pointing towards the reduced functionality of glandular secretory processes, causing the horse’s inability to sweat and the need for further research to find a potential treatment.

Overview of Anhidrosis in Horses

• The paper focuses on anhidrosis, a condition affecting a small (approximately 10 +/- 5%) proportion of horses. Anhidrosis is described as the inability to sweat properly.
• According to the authors, the condition is believed to be triggered by prolonged exposure to extreme climatic stressors such as intense heat and high humidity.
• The article suggests that continuous exposure to these conditions leads to an inappropriate response in the horses, contributing to the onset of anhidrosis.

Role of Glandular Secretory Cells

• The research indicates that the gradual decline of anhidrosis is caused by the failure of glandular secretory cell processes.
• The study suggests that this process starts with desensitization and subsequent down-regulation of the cell receptors due to continuous adrenaline-driven hyperactivity.
• The condition progresses towards secretory failure and concludes with gradual, probably irreversible, glandular dedifferentiation and ultimate degeneration.

Need for Further Research

• The authors highlight the need for more research into the secretory and transcriptional processes in horses with this condition.
• Documenting the changes that occur within the glandular secretory mechanism could be vital to understanding the syndrome and developing an effective treatment to deal with this problem in horses.
