(Submitter supplied) PBMC from house dust mite (HDM) sensitized atopics were cultured in the presence or absence of HDM extract for 24 hours. At the termination of the cultures, CD4 T cells were isolated using immunomagnetic separation. Gene expression was profiled on microarrays.

(Submitter supplied) Peripheral blood samples from children enrolled in the URECA cohort were collected at age 2. In short, at each URECA research center, within 16 hours of blood collection, mononuclear cells were separated and incubated (48 hours, 37C, 5% CO2) in the presence of German cockroach extract (10mg/mL; CR), dust mite extract (Dermatophagoides pteronyssinus, 10mg/mL; DM), tetanus toxoid (5mg/mL; TT), or medium alone (NS).

(Submitter supplied) Uric acid stored in the fat body of cockroaches is a nitrogen reservoir mobilized in times of scarcity. The discovery of urease in Blattabacterium cuenoti, the primary endosymbiont of cockroaches, suggests that the endosymbiont may participate in cockroach nitrogen economy. However, bacterial urease may only be one piece in the entire nitrogen recycling process from insect uric acid. Thus, in addition to the uricolytic pathway to urea, there must be glutamine synthetase assimilating the released ammonia by the urease reaction to enable the stored nitrogen to be metabolically usable.

(Submitter supplied) Atopic asthma is a chronic inflammatory disease of the lungs that is commonly associated with a Th2 response. The role of allergen-specific IgG in the initiation and development of allergic airway inflammation is still poorly understood; however, a receptor of IgG-immune complexes, CD16, has been demonstrated to promote augmentation of Th2 responses. To identify what genes downstream of CD16 signaling may be contributing to development of a Th2 response, we use ovalbumin (OVA) as our model antigen and compared wildtype and CD16-/- BMDCs that were treated overnight with OVA or OVA-immune complex.

(Submitter supplied) Allergic asthma and rhinitis are two common chronic allergic diseases that affect the lungs and nose, respectively. Both diseases share clinical and pathological features characteristic of excessive allergen-induced type 2 inflammation, orchestrated by memory CD4+ T cells that produce type 2 cytokines (TH2 cells). However, a large majority of subjects with allergic rhinitis do not develop asthma, suggesting divergence in disease mechanisms. more...

(Submitter supplied) Defective interleukin-6 (IL-6) signaling has been associated with Th2 bias and elevated IgE. However, the underlying mechanism by which IL-6 may prevent the development of Th2-driven diseases remains unknown. Using a model of house-dust-mite (HDM)-induced Th2 differentiation and allergic airway inflammation, we show here that IL-6 signaling in allergen-specific T cells was required to prevent Th2 development and subsequent IgE response and allergic inflammation. more...

(Submitter supplied) Allergic asthma develops from allergen exposure in early childhood and progresses into adulthood. The central mediator of progressive allergic asthma is allergen-specific, T helper 2 (Th2) resident memory cells (TRMs). However, whether the immature lung facilitates residence of Th2-TRMs is unknown. Employing a mouse model of progressive allergic inflammation from neonates to adults, we found that maturing sympathetic nerves enable a dopamine-enriched lung environment in early life that promotes establishment of allergen-specific Th2-TRMs. more...

(Submitter supplied) IgE antibody is known as a common mediator of allergic responses, generally produced in type 2 immune responses to allergens. It is known that IgE binding to FcεRI without allergen binding promotes survival or proliferation of mast cells, basophils and other cells. Thus, spontaneously produced IgE, namely natural IgE, can increase an individual’s susceptibility to allergic diseases. Mice with a genetic defect in MyD88, a major signaling molecule downstream of Toll-like receptors, have a high level of serum natural IgE, the mechanism for which remains unknown. more...

(Submitter supplied) Viral-induced severe asthma exacerbations in children are characterized by IRF7hi and IRF7lo molecular phenotypes. We have developed an experimental animal model that mirrors these response patterns in asthma-resistant PVG and asthma-susceptible BN rats respectively. We aimed to i) characterize the immunological and molecular hallmarks of PVG and BN responses to virus/allergen exposure, and (ii) evaluate the utility of innate immune training with the bacterial lysate OM85 to attenuate ensuing inflammation. more...

(Submitter supplied) Asthma exacerbations in children are associated with respiratory viral infection and atopy, resulting in systemic immune activation and infiltration of immune cells into the airways. The gene networks driving the immune activation and subsequent migration of immune cells into the airways remains incompletely understood. Cellular and molecular profiling of PBMC was employed on paired samples obtained from atopic asthmatic children (n = 19) during acute virus-associated exacerbations and later during convalescence. more...
