Abstract Background: Obesity and insulin resistance (IR) are conditions of increasing prevalence in populations of equids worldwide. The immune impairment described in metabolic dysfunction status in humans has been extensively reported with minimal data regarding horses. The objective of the study was to evaluate the effect of obesity as an isolated factor and in association with insulin resistance on apoptosis, phagocytosis and oxidative burst activity of neutrophils isolated from peripheral blood of lean and obese adult horses with or without insulin resistance, basally and after induction of hyperglycemia through an oral glucose test. Results: No differences in apoptosis were observed between experimental groups at any time point. Phagocytic capacity was significantly diminished at baseline in the obese-IR group (P<0.05) but increased after stimulation of hyperglycemia (P=0.007). Basal reactive oxygen species production differed significantly (P=0.0001) between the obese-insulin sensitive (IS) and lean-IS or obese-IR groups, and decreased significantly after stimulation of hyperglycemia in the lean-IS and obese-IS groups (P<0.05).Conclusions: Results from this study showed that both metabolic status itself, and acute hyperglycemia, are factors that influence PMNs functionality in horses, specifically phagocytosis and oxidative burst. This indicates the need for close monitoring of immune function in horses with inflammatory disease and concurrent obesity and insulin resistance.

The present study examined the effects of autonomic drugs and glucose on the insulin and glucose concentrations of sham-operated rats and of rats with ventromedial hypothalamic (VMH) lesions and obesity. In the basal condition both epinephrine and atropine significantly decreased serum insulin levels in VMH-lesioned but not sham-operated rats. During glucose stimulation of insulin secretion in VMH-lesioned rats, epinephrine inhibited the increase of insulin by 83% and atropine inhibited it by 42%; whereas in sham-operated rats, epinephrine inhibited it by 70% and atropine inhibited it by 34%. Epinephrine with atropine completely blocked the increase of insulin in response to glucose in both VMH-lesioned and sham-operated rats. In the basal condition, epinephrine together with propranolol significantly decreased serum insulin levels in VMH-lesioned but not sham-operated rats. Epinephrine with phentolamine, on the other hand, markedly increased insulin in the VMH-lesioned rats and to a lesser degree in the sham-operated rats. During glucose stimulation epinephrine with propranolol inhibited the increase of insulin in both groups. Epinephrine with phentolamine or isoproterenol markedly increased serum insulin in VMH-lesioned rats. These results suggest that stimulation of the vagus nerve and increased sensitivity of the beta-receptors on the beta-cells of the islet contribute to the development of hyperinsulinemia. The sympathetic contribution may also be through suppression of alpha-adrenergic receptors.
