multi gene family), showed significant sequence and structural similarity to Cyn d 1. This protein was expressed in E. coli and the recombinant protein did not react with serum IgE from grass pollen allergic patients, suggesting that EXPB1 represented a non-allergenic homologue of grass group 1 allergens. It is proposed that differences in the amino acid sequence are responsible for the differe...

Insects have been consumed as food in diverse cultures worldwide, gaining recognition a sustainable and nutritious source. This systematic review aims to update information on the impact of insect consumption human health based randomized controlled trials (RCTs) allergenicity assessment studies. Following PRISMA guidelines, studies published last 10 years were analyzed. From one-thousand sixty...

boophilus genus ticks are responsible for transferring some pathogens and reducing production factors in cattle. tropomysin (tpm) protein has actin regulator activity and playing important role in immune and allergic reactions. the main goal is to determine different aspects of phylogenetic, similarity, homology, structure and allergenicity of tpm protein. in prior study, we identified tpm by u...

background: dermatophagoides farinae and dermatophagoides pteronyssinus are house dust mites (hdm) that they cause severe asthma and allergic symptoms. tropomyosin protein plays an important role in mentioned immune and allergic reactions to hdms. here, tropomyosin protein from dermatophagoides spp. was comprehensively screened in silico for its allergenicity, antigenicity and similarity/conser...

BACKGROUND Parasite-specific IgE is thought to correlate with protection against Schistosoma mansoni infection or re-infection. Only a few molecular targets of the IgE response in S. mansoni infection have been characterised. A better insight into the basic mechanisms of anti-parasite immunity could be gained from a genome-wide characterisation of such S. mansoni allergens. This would have repe...

Parabens, methyl, ethyl, propyl, benzyl, and butyl, are the most common preservatives in use today. They are the alkyl esters of p-hydroxybenzoic acid and are used extensively because they are relatively nonirritating and nontoxic and offer good antimicrobial coverage. Testing for paraben allergen can be done by patch testing. Two cases of allergic contact dermatitis (ACD) to parabens are used ...

Allergenicity is defined in this chapter as the capacity to elicit an IgE immune response upon animal or human immunisation or exposure. All newly expressed proteins in genetically modified plants that could be present in the final food or feed destined for human or animal consumption should be assessed for their potential to cause allergic reactions. This should include consideration of whethe...
