Our results showed a positive correlation between the levels of anti-Galα1-3Galβ1-4GlcNAc and anti-Galα1-3Gal IgA and the occurrence and development of granulomas in the lungs of A. fumigatus-infected turkeys, suggesting a pro-inflammatory role of anti-α-Gal IgA. This evidence concerns the gene CD79A and Granuloma.
