Laboratory Development Manager

Dr. Jennifer Canizales runs the Occupational and Environmental Medicine Lab Service at the National Heart and Lung Institute (NHLI), where she oversees diagnostic services for occupational respiratory diseases. Her work focuses on developing new immunological assays and collaborating with researchers at Imperial College and other institutions on environmental health research.

Prior to this, Jennifer worked on malaria serosurveillance projects at the London School of Hygiene & Tropical Medicine and contributed to allergy research with the SPIRAL study at Imperial College London. Today, she combines lab management with ongoing research to improve diagnostic techniques in occupational respiratory disease.

Laboratory animal allergy is preventable in modern research facilities

Article
We surveyed 750 laboratory animal workers and measured airborne Mus m 1 (mouse allergen) levels in seven UK institutions. We compared the prevalence of sensitisation to mouse proteins (by specific IgE assay or skin prick test) and of work-related allergic symptoms in IVC-only and open cage units.

Measurement of specific IgG4 anti-mouse urine antibodies

Book chapter

IgG4 and its role in immune tolerance has been investigated widely. Symptom reduction and improved clinical outcomes in immunotherapy trials are associated with significant increases in allergen-specific IgG4 antibodies. Natural immune tolerance observed in beekeepers and cat owners has also been associated with elevated levels of bee venom and cat allergen-specific IgG4, respectively. Functionally, allergen-specific IgG4 has been shown to reduce the binding of IgE-allergen complexes to B cells, a key step in the initiation of the type 1 hypersensitivity allergic response.
