Patterns of Mouse Allergen–Specific IgE and IgG4 in Contemporary Animal Research Environments

Key Points

• The study aims to investigate the relationship between mouse-specific IgG4 and IgE levels in laboratory workers.
• Examined IgG4 and IgE levels in serum samples from mouse-sensitized laboratory workers.
• Compared levels between workers with and without asthma symptoms.
• Analyzed the association of IgG4 with the inhibition of IgE-allergen complex binding to B cells.
• Mouse-sensitized workers without asthma symptoms have higher IgG4 levels than those with asthma.
• Higher IgG4 levels correlate with reduced binding of IgE-allergen complexes to B cells.
