Allergenic activity of a major grass pollen allergen is elevated in the presence of nasal secretion.
Phl p5 is a major allergen of timothy grass and causes rhinitis and bronchial asthma in nearly all patients allergic to grass pollen. The biochemical processing of this molecule by the nasal mucosa at its first encounter and possible changes of its biologic activity are unknown. Two isoforms of the allergen were expressed in Escherichia coli and subsequently purified. Conversion of these prepar...
Treatments to reduce solids content in liquid manure have been developed, but little information is available on gaseous N emissions and plant N uptake after application of treated liquid swine manure (LSM). We measured crop yield, N uptake, and NH3 and N2O losses after the application of mineral fertilizer (NH4 NO3), raw LSM, and LSM that was decanted, filtered, anaerobically digested, or chem...
We analyzed the cDNA sequence data of complementarity determining regions (CDR3) of epitope mapped alphabeta TCR of T cell clones (TCC). The TCC were specific for the major timothy grass (Phleum pratense) pollen allergen Phl p 1 and were derived from the peripheral blood of seven unrelated grass pollen-allergic individuals. Each TCR recognized one of two immunodominant T cell epitopes, PP73 or ...
BACKGROUND Group 5 allergens are small proteins that consist of two domains. They belong to the most potent respiratory allergens. OBJECTIVE To determine the binding sites and to study allergic patients' IgE recognition of the group 5 allergen (Phl p 5) from timothy grass pollen using human monoclonal IgE antibodies that have been isolated from grass pollen allergic patients. METHODS Using ...
Group V major allergen Phl p 5b of timothy grass pollen induces allergic rhinitis and bronchial asthma in 90% of grass pollen-allergic patients. In addition to its allergenicity ribonuclease activity has recently been attributed to this 29-kDa protein. The allergen was expressed in Escherichia coli and subsequently purified. Spontaneous conversion of these preparations to a mixture of various f...
The airway epithelium forms a physical, chemical and immunological barrier against inhaled environmental substances. In asthma, these barrier properties are thought to be abnormal. In this study, we analysed the effect of grass pollen on the physical and immunological barrier properties of differentiated human primary bronchial epithelial cells. Following exposure to Timothy grass (Phleum prate...
A dataset of grasses and respective silages was collected by systematically varying the harvesting time in primary growth (n = 27) and in regrowth (n = 25). The swards were mixtures of timothy and meadow fescue. The grasses were ensiled unwilted with formic acid. Fixed or mixed regression procedure of SAS was used to investigate the relationships between composition of grasses and respective si...
سابقه و هدف: آلرژنهای هوائی از جمله علل تشدید کننده کهیر مزمن می باشند. تست پوستی پریک یک تست مناسب برای اثبات واکنش فوری می باشد. هدف از این مطالعه بررسی شیوع تست پوستی مثبت به آلرژنهای هوایی در بیماران دارای کهیر مزمن می باشد. مواد و روشها: این مطالعه مقطعی طی سه سال بر روی در بیماران دارای کهیر مزمن انجام شد. پس از شرح حال و معاینه بالینی بیماران تحت آزمایش CBC,diff، ESR، آزمایش مدفوع، تست ...
