“…In addition to the presence or absence of atopy, differences in maternal exposure to Der p could also be responsible for differences in IgG levels in maternal blood, colostrum and cord blood. Although we did not measure Der p levels in subjects’ homes, we did not favour this hypothesis because all subjects live in a region where Der p is found uniformly in very high concentration [35].…”

Mother to Child Transfer of IgG and IgA Antibodies Against Dermatophagoides pteronyssinus

There is strong evidence from animal models that placental and/or breast milk‐mediated transfer of maternal allergen‐specific IgG prevents allergic immune responses in the progeny. Both human and animal data also point to IgA as having an important regulatory role. In contrast, little is known about maternal transfer of IgG and IgA specific for respiratory allergens in humans. Dermatophagoides pteronyssinus (Der p) is an indoor allergen that is a major cause of asthma worldwide. We analysed maternal to child Der p‐specific IgG and IgA transfer in a cohort of 77 paired maternal and child samples. We found Der p‐specific IgG and its IgG1, IgG2 and IgG4 subclasses in all cord blood samples. Except for IgG1, cord levels were higher in newborns from atopic mothers (n = 29) compared to non‐atopic mothers (n = 48). Der p‐specific IgA was found in all colostrum samples and levels were independent of maternal atopic status. Notably, anti‐Der p IgG was also found in colostrum and levels were higher in atopic mothers. We believe that our work is a critical first step in the identification of early factors that may impact asthma development and should guide the development of clinical studies that assess whether Der p‐specific IgG and IgA protect children from allergy as demonstrated in animal models.

“…Higher dust mite allergen levels are associated with wool bedding and inner-spring mattresses. 67 Although mattresses are major reservoirs of mite allergen, studies have shown significantly higher levels of mite allergen 68,69 and mite bodies 70,71 in mattress bases (box springs) than in mattresses.…”

“…Storage mites are prevalent in stored grains, hay and straw, poultry and livestock feed, and barn dust and have also been reported to occur in mattresses, bedding, carpets and furniture in homes where sometimes they are present in significant numbers (Boquete et al 2006;Croce et al 2000;de Oliveira et al 2003;Valdivieso et al 2006). Common species of these storage mites include Acarus siro, Chortoglyphus arcuatus, Tyrophagus putrescentiae, and Lepidoglyphus destructor among many other species.…”

Cross-reactivity between storage and dust mites and between mites and shrimp

et al. 2008

Many patients have sensitivities to multiple species of storage and house dust mites. It is not clear if this is because patients have multiple sensitivities to species-specific mite allergens or if these mites share many cross-reacting allergens. Our objective was to further define the cross-allergenicity between several species of storage and house dust mites using crossed-immunoelectrophoresis (CIE), crossed-radioimmunoelectrophoresis (CRIE), immunoblotting, and ELISA. CIE and CRIE reactions revealed that storage mites shared two cross-antigenic molecules and one of these bound IgE in a serum pool from mite allergic patients. Antibody in anti-sera built to each species of mite recognized many SDS-PAGE resolved proteins of other mite species and this suggested the potential for other cross-reactive allergens. Among patient sera, IgE bound to many different proteins but few had IgE that bound to a protein with common molecular weights across the mite species and this suggested mostly species-specific allergens. Antiserum built to each mite species precipitated one protein in shrimp extracts that bound anti-Der p 10 (tropomyosin) and IgE in the serum pool. Anti-Der p 10 showed strong binding to shrimp tropomyosin but very little to any of the mite proteins. ELISA showed the mite extracts contained very little tropomyosin. The storage and dust mites investigated contain mostly species-specific allergens and very small amounts of the pan-allergen tropomyosin compared to shrimp and snail.
