With the approval of two grass tablets and one ragweed tablet for sublingual immunotherapy (SLIT) by the US FDA in April 2014, the practice of allergy immunotherapy (AIT) in the USA has dramatically changed. Until this time, there were no approved allergen extracts for sublingual administration and
BACKGROUND
The role of allergen-specific CD4+ T lymphocytes in the pathophysiology of atopic disease is well established. Previous studies on allergen-specific T-cell responses have focused on the recognition of single major allergens to identify T-cell epitopes.
OBJECTIVE
However, it is not clear
BACKGROUND
Conventional diagnostic tests (such as radioallergosorbent test [RAST] and skin prick test [SPT]) use native raw pollen allergen extracts to establish allergy. However, recombinant allergens may offer important advantages compared with their natural counterparts.
OBJECTIVE
This study
BACKGROUND
The diagnostic approach to grass pollen allergy is now possible by detecting specific IgE to its allergenic components.
OBJECTIVE
To compare the IgE reactivity to a timothy grass pollen extract with the IgE reactivity to eight allergenic components from the same source (Phl p 1, 2, 4, 5,
BACKGROUND
The introduction of molecular diagnoses has provided evidence of the existence of several different allergenic profiles in grass-sensitised individuals, reflecting the large number of allergens involved. This methodology has become a potent tool for a correct diagnosis and for the
The typing of common Phleol Pollen and wheat Antigen has been realized with these Antigens Fractions from PASTEUR Institute using FPLC PHARMACIA Chromatograph. The discover of commun Antigen has been obtained with RAST Inhibition technic. It exist common Antigen fractions between phleol and wheat,
BACKGROUND
Grass pollen allergy is one of the most common allergies worldwide, and patients often show sensitization to an array of phylogenetically related species.
OBJECTIVE
To determine the effect of specific immunotherapy (SIT) with Phleum pratense extract on induction of the immune response to
BACKGROUND
Allergy to grass pollen is typically associated with serum IgE antibodies to group 1 and/or group 5 allergens, and additionally often to one or several less prominent allergens. Most of the grass pollen allergens identified to date have been characterized in detail by molecular,
BACKGROUND
Although there have been many studies of the prevalence of latex allergy in populations deemed to be at risk, little is known of the potential allergic susceptibility to latex products prevailing in the general population.
OBJECTIVE
To assess the possible prevalence of allergy to latex
BACKGROUND
Group 4 grass pollen allergens represent glycoproteins with a molecular weight of 50 to 60 kd, which are present in many grass species. Almost 75% of patients allergic to grass pollen display IgE reactivity to group 4 allergens, which hence can be regarded as major grass pollen
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
Almost 500 million people worldwide suffer from Type I allergy, a genetically determined immunodisorder which is based on the production of IgE antibodies against per se harmless antigens (allergens). Due to their worldwide distribution and heavy pollen production, grasses represent a major allergen
BACKGROUND
Although most of the common allergen extracts that are used for diagnosis of type 1 hypersensitivity are now well standardized, this gives no assurance that they are within the concentration range that gives the best chance of a true diagnosis.
OBJECTIVE
The objective of this study was to
Due to the wide distribution and heavy pollen production of grasses, approximately 50% of allergic patients are sensitized against grass pollen allergens. cDNAs coding for two isoforms and four fragments of a major timothy grass (Phleum pratense) pollen allergen, Phl p 6, were isolated by IgE
BACKGROUND
Release of cytoplasmic granules from grass pollen upon contact with water is thought to be an important source of airborne allergens.
OBJECTIVE
To investigate the humoral and cellular responses to intratracheal instillation of Phleum pratense (timothy grass) pollen cytoplasmic granules
