IgE, IgGa, IgGb and IgG(T) serum antibody levels in offspring of two sires affected with equine recurrent airway obstruction.
Abstract: Equine recurrent airway obstruction (RAO) is a chronic lower airway disease of the horse caused by hypersensitivity reactions to inhaled stable dust, including mould spores such as Aspergillus fumigatus. The goals of this study were to investigate whether total serum IgE levels and allergen-specific IgE and IgG subclasses are influenced by genetic factors and/or RAO and whether quantitative trait loci (QTL) could be identified for these parameters. The offspring of two RAO-affected sires (S1: n=56 and S2: n=65) were grouped by stallion and disease status, and total serum IgE levels and specific IgE, IgGa, IgGb and IgG(T) levels against recombinant Aspergillus fumigatus 7 (rAspf7) were measured by ELISA. A panel of 315 microsatellite markers covering the 31 equine autosomes were used to genotype the stallions and their offspring. A whole-genome scan using half-sib regression interval mapping was performed for each of the IgG and IgE subclasses. There was no significant effect of disease status or sire on total IgE levels, but there was a significant effect of gender and age. rAspf7-specific IgGa levels were significantly higher in RAO-affected than in healthy horses. The offspring of S1 had significantly higher rAspf7-specific IgGa and IgE levels than those of S2. Five QTLs were significant chromosome-wide (P<0.01). QTLs for rAspf7-specific IgGa and IgE were identified on ECA 1, for rAspf7-specific IgGa and IgGb on ECA 24 and for rAspf7 IgGa on ECA 26. These results provide evidence for effects of disease status and genetics on allergen-specific IgGa and IgE.

This research was conducted to investigate the influence of genetic factors and the chronic lower airway disease in horses called recurrent airway obstruction (RAO) on certain types of serum antibodies. The study also aimed to identify specific genetic loci associated with these antibodies. The results suggest there are inherited influences on the antibodies specific to an allergen commonly found in dusty stables that can affect horses with RAO.
Objective and Methodology
- The researchers set out to specifically investigate whether total serum IgE levels and allergen-specific IgE and IgG subclasses are influenced by genetic factors and/or RAO.
- This goal in mind, they measured the subjects’ total serum IgE levels and specific IgE, IgGa, IgGb, and IgG(T) levels against a particular allergen found in mouldy stable dust using an ELISA analysis.
- The subjects of this study were the offspring of two RAO-affected stallions. The team performed a whole-genome scan using half-sib regression interval mapping on each of the IgG and IgE subclasses for 315 microsatellite markers across 31 horse chromosomes.
Results
- The total IgE levels were not significantly affected by disease status or the sire (stallion father) but were significantly influenced by gender and age.
- Mould allergen-specific IgGa levels were notably higher in RAO-affected horses compared to healthy ones.
- The children of Stallion 1 (S1) showed significantly higher allergen-specific IgGa and IgE levels than those of Stallion 2 (S2).
- The research identified five quantitative trait loci (QTLs) on different chromosomes that were significant and an influence on the allergen-specific IgGa and IgE levels.
Implications
- This study gives substantial evidence pointing towards the effects of disease status and genetics on allergen-specific IgGa and IgE antibodies. Understanding these influences may provide avenues for more effective treatment and prevention strategies for equine recurrent airway obstruction disease.
- The findings regarding higher allergen-specific antibodies in RAO-affected horses indicate a possible role of these antibodies in the disease, which warrants further study.
