Gamahonolides A, B, and Gamahorin, Novel Antifungal Compounds from Stromata of Epichloe typhina on Phleum pratense.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

Four novel antifungal compounds, gamahonolides A and B, gamahorin, and 5-hydroxyl-4-phenyl-2(5H)-furanone, were isolated from stromata of Epichloe typhina on Phleum pratense. Their structures were determined by spectroscopic methods. The absolute configuration of gamahonolide A was determined by its

Timothy grass pollen therapeutic vaccine: optimal dose for subcutaneous immunotherapy.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

OBJECTIVE To establish the optimal dose of Phleum pratense subcutaneous immunotherapy (SCIT) in patients with allergic rhinoconjunctivitis with/without asthma. METHODS One hundred and fifty-one patients were randomized to receive SCIT 0.25, 0.5, 1.0, 2.0 or 4.0 skin-prick test units (SPT) or

The efficacy and safety of the Timothy grass allergy sublingual immunotherapy tablet in Canadian adults and children.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND The effect of sublingual Timothy grass immunotherapy tablet 2800 BAU (grass SLIT-T) has been evaluated in three North American trials in adults and children who have allergic rhinitis with or without conjunctivitis (AR/C). This paper examines the effects of grass SLIT-T in

Timothy grass pollen extract-induced gene expression and signalling pathways in airway epithelial cells.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND Grass pollen allergy is one of the most common allergies worldwide and airborne allergens are the major cause of allergic rhinitis. Airway epithelial cells (AECs) are the first to encounter and respond to aeroallergens and are therefore interesting targets for the development of new

Quantitative assessment of immediate cutaneous hypersensitivity in a mouse model exhibiting an IgE response to Timothy grass allergens.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND A variety of allergic reactions can be induced in mice, as measured by the induction of specific IgE. Functional read-out parameters include skin reactions and airway constriction. The aim of this study was to establish an improved quantitative assessment of the immediate cutaneous

T cell epitopes of the timothy grass pollen allergen Phl p 5 of mice and men and the detection of allergen-specific T cells using Class II Ultimers.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND Knowledge of allergen-specific T cell epitopes is a prerequisite not only for therapeutic approaches but also for elucidating immunological mechanisms of type I allergy. Ex vivo detection of allergen-specific T cells using class II tetramer technology has become an important tool for

Characterization of immunoglobulin E responses in Balb/c mice against the major allergens of timothy grass (Phleum pratense) pollen.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND Grass pollen, such as that from timothy grass (Phleum pratense), represents a major cause of type I allergy. OBJECTIVE To characterize the IgE immune response and to identify the major allergens eliciting an IgE response in a mouse model using pollen extract of P. pratense for

Hypoallergenic mutants of the Timothy grass pollen allergen Phl p 5 generated by proline mutations.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND Phl p 5 is a major allergen of Timothy grass (Phleum pratense). A recombinant native Phl p 5 has already been used in clinical trials of allergen-specific immunotherapy as a component of a cocktail of allergens. Recombinant hypoallergenic allergens should further improve the treatment by

Dose-response relationship of a new Timothy grass pollen allergoid in comparison with a 6-grass pollen allergoid.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND Subcutaneous allergen immunotherapy with grass pollen allergoids has been proven to be effective and safe in the treatment of patients with allergic rhinoconjunctivitis. Based on the extensive cross-reactivity among Pooideae species, it has been suggested that grass pollen extracts could

IgE profiles of Bermuda grass pollen sensitised patients evaluated by Phleum pratense allergens Phl P 1, 2, 4, 5, 6 , 7, 11, 12.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND Despite the difference in geographical dominance of certain grasses, a high degree of allergenic similarity or cross-reactivity between Bermuda grass pollen (BGP) and timothy grass pollen (TGP) has been previously demonstrated. The aim of the present study was to ascertain the

Primary structure, recombinant expression, and molecular characterization of Phl p 4, a major allergen of timothy grass (Phleum pratense).

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

Grass pollen allergy is one of the most important allergic diseases world-wide. Several meadow grasses, like timothy grass and rye grass, contribute to allergic sensitizations, but also allergens from extensively cultivated cereals, especially rye, make a profound contribution. The group 4 allergens

cDNA cloning of a major allergen from timothy grass (Phleum pratense) pollen; characterization of the recombinant Phl pV allergen.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

We isolated a cDNA encoding a major grass pollen allergen from a timothy grass (Phleum pratense) pollen expression cDNA library using allergic patients' IgE. The complete cDNA encoded an allergen that binds IgE from about 80% of grass pollen-allergic patients. Significant sequence homology was found

The high molecular mass allergen fraction of timothy grass pollen (Phleum pratense) between 50-60 kDa is comprised of two major allergens: Phl p 4 and Phl p 13.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND More than 70% of the patients allergic to grass pollen exhibit IgE-reactivity against the high molecular mass fraction between 50 and 60 kDa of timothy grass pollen extracts. One allergen from this fraction is Phl p 4 that has been described as a basic glycoprotein. A new 55/60 kDa

Double-blind study of tolerability and antibody production of unmodified and chemically modified allergen vaccines of Phleum pratense.

Se sèlman itilizatè ki anrejistre yo ki ka tradwi atik yo

BACKGROUND The physicochemical modification of allergen extracts provides a chance for administering higher doses of allergen vaccines. OBJECTIVE To evaluate the safety of a chemically modified (depigmented-glutaraldehyde polymerized) therapeutic vaccine of Phleum pratense administered at doses that

Possible therapeutic potential of a recombinant group 2 grass pollen allergen-specific antibody fragment.

The induction of blocking IgG antibodies that compete with IgE for allergen binding is one important mechanism of allergen-specific immunotherapy. The application of blocking antibodies may be an alternative treatment strategy. A synthetic gene coding for a single-chain fragment (ScFv) specific for
