Betv1 allergen For many individuals, the arrival of spring brings not just blooming flowers but also unwelcome respiratory symptomsMajor allergenBet v 1. Gene: betv1. Status: UniProtKB unreviewed (TrEMBL). Organism: Betula pendula (European white birch) (Betula verrucosa).. Among the key instigators of these seasonal woes is Bet v 1, a protein predominantly found in birch pollen.AF069: Bet v 1 family Recognized as the major birch pollen allergen, Bet v 1 is responsible for a significant portion of type I allergies, a condition affecting approximately one in five people.Bet v 1is the most abundant white birch pollen protein (Betula verrucosa). It is a protein belonging to the PR-10 family (proteins related to pathogenicity) ... This article delves into the scientific understanding of Bet v 1, its properties, its role in allergic reactions, and the ongoing research surrounding it.
Bet v 1 is scientifically classified as a protein belonging to the PR-10 protein family, also known as pathogenesis-related proteins.作者：M Gajhede·1996·被引用次数：502—TheBet v 1protein5•6 from B. verrucosa is the major allergen in birch and is homologous to the major pollen allergens from taxonomically related trees7. Aln g ... These proteins are believed to play a role in plant defense mechanisms. Bet v 1 is specifically derived from the European white birch ( *Betula pendula* or *Betula verrucosa*)Recombinant Betula pendula allergenBet v 1, Biotinylated was expressed in E. coli and purified by affinity chromatography using a His tag.. Its presence in birch pollen is significant, with some sources indicating it can constitute up to 95% of the pollen extract.Major allergen Bet v 1 - Betula pendula (European white ... This abundance makes it a primary trigger for sensitization and subsequent allergic reactions.
The allergenic potential of Bet v 1 lies in its ability to elicit an immunoglobulin E-mediated (IgE-mediated) immune response. When an allergic individual inhales birch pollen, their immune system mistakenly identifies Bet v 1 as a harmful substance. This triggers the production of IgE antibodies specific to Bet v 1. Upon subsequent exposure, these IgE antibodies bind to mast cells and basophils, leading to the release of histamine and other inflammatory mediators.Bet v 1 from Birch Pollen Is a Lipocalin-like Protein Acting ... This cascade of events results in the characteristic symptoms of birch pollen allergy, such as sneezing, runny nose, itchy eyes, and in severe cases, asthma.Bet v 1is the most abundant white birch pollen protein (Betula verrucosa). It is a protein belonging to the PR-10 family (proteins related to pathogenicity) ...
A crucial aspect of Bet v 1's allergenic profile is its cross-reactivityMajor allergen Bet v 1 - Betula pendula .... This means that the immune system's response to Bet v 1 can extend to similar proteins found in other plant-based foods and pollensRecombinant Bet v 1 (RP-BV1-1). This phenomenon, known as oral allergy syndrome (OAS), is frequently observed in individuals sensitized to birch pollen. For instance, Bet v 1 shares a high degree of sequence identity with Mal d 1, the major allergen in apples. Consequently, people allergic to birch pollen often experience reactions when consuming raw apples, as well as other fruits like peaches and pears, and vegetables like carrots and celeryBet v 1, the major birch pollen allergen, and Mal d .... This cross-reactivity contributes to a broader spectrum of allergic symptoms and dietary restrictions for affected individuals.作者：F Roth-Walter·2014·被引用次数：94—The major birch pollen allergenBet v 1is considered the prototype for the PR-10 protein family causing respiratory allergy. Here, we give structural evidence ...
The scientific community has extensively studied Bet v 1Bet v 1, Biotinylated. It is described as a heat labile protein with a molecular weight of approximately 17.5 kDa (kilodaltons). Research efforts have focused on elucidating its structure, function, and allergenic epitopes.IgE to Bet v 1 and profilin: Cross-reactivity patterns and ... The three-dimensional structure of Bet v 1 has been determined through techniques like X-ray crystallography and Nuclear Magnetic Resonance (NMR), providing insights into how it interacts with IgE antibodies.Bet v 1 Antibodies
The Bet v 1 fold is recognized as an ancient and versatile scaffold that binds various ligands作者：M Gajhede·1996·被引用次数：502—TheBet v 1protein5•6 from B. verrucosa is the major allergen in birch and is homologous to the major pollen allergens from taxonomically related trees7.

This structural characteristic is fundamental to understanding its allergenic capabilitiesPSC-24-904 · Share · Click to email a link to a friend (Opens in new window) Email · Click to share on X (Opens in new window) X · Click to share on Facebook ( .... The protein family itself, PR-10, is widespread, and closely-related, cross-reactive allergens have been identified in the pollen of other trees, further emphasizing the significance of Bet v 1 as a prototype for this protein group.
Significant progress has been made in producing recombinant allergen Bet v 1 in laboratory settingsBet v 1, Biotinylated. This allows for standardized testing and research without relying solely on natural pollen extracts. Recombinant Bet v 1, often expressed in systems like *E. coli* or SF9 cells, is purified and can be used in diagnostic tests and for developing immunotherapy strategies.Recombinant allergen Bet v 1 Different forms, such as Biotinylated Bet v 1 and Natural Bet v 1, are also available for specialized research applications作者：P Gevaert·2022·被引用次数：78—Novel antibody cocktail targetingBet v 1rapidly and sustainably treats birch allergy symptoms in a phase 1 study.
Furthermore, research into Bet v 1 antibodies is ongoing. Scientists are developing novel antibody cocktails targeting Bet v 1 to potentially treat birch allergy symptoms rapidly and sustainably. Studies have explored targeting immunodominant Bet v 1 epitopes with monoclonal antibodies (mAbs) to prevent or mitigate the allergic response.
Given its prevalence, Bet v 1 is considered a marker allergen for primary sensitization to pollen. This means that sensitization to Bet v 1 often indicates an initial allergic response to pollen, which can then lead to secondary sensitivities, such as those seen in OAS.X-ray and NMR structure of Bet v 1, the origin of birch ... Diagnostic tools, including RAST inhibition studies, have shown that a high percentage of patients sensitized include those with IgE against Bet v 1. The availability of Bet v 1 protein and related antibodies facilitates accurate diagnosis and management of birch pollen allergy.
In summary, Bet v 1 stands as a pivotal player in the landscape of seasonal allergies.Bet v 1is a heat labile protein with a molecular weight of 17.5 kDa belonging to the PR-10 protein family. It is the major allergen of birch pollen. Up to 95% ... Its role as the major birch pollen allergen, coupled with its cross-reactive properties and extensive scientific investigation, underscores its importance in understanding and managing allergic diseases. Ongoing research into its structure, epitopes, and potential therapeutic targets promises further advancements in alleviating the burden of birch pollen allergy for millions worldwide.
