Identification of a new allergen from Amaranthus retroflexus pollen, Ama r 2.
BACKGROUND Pollinosis from Amaranthus retroflexus pollen is a common cause of respiratory allergy in Iran with a high positive rate (68.8%) among Iranian allergic patients. The aim of the present study was to evaluate the allergenicity of the A. retroflexus pollen profilin. METHODS Using sera from twelve patients allergic to A. retroflexus pollen, IgE-binding proteins from the A. retroflexus ...
متن کاملCloning and Expression of Ama r 1, as a Novel Allergen of Amaranthus retroflexus Pollen
Sensitisation to Amaranthus retroflexus pollen is very common in tropical and subtropical countries. In this study we aimed to produce a recombinant allergenic Ole e 1-like protein from the pollen of this weed. To predict cross-reactivity of this allergen (Ama r 1) with other members of the Ole e 1-like protein family, the nucleotide sequence homology of the Ama r 1 was investigated. The expres...
متن کاملRole of Ethylene Metabolism in Amaranthus retroflexus.
(14)C-Ethylene was metabolized by etiolated pigweed seedlings (Amaranthus retroflexus L.) in the manner similar to that observed in other plants. The hormone was oxidized to (14)CO(2) and incorporated into (14)C-tissue components. Selected cyclic olefins with differing abilities to block ethylene action were used to determine if ethylene metabolism in pigweed is necessary for ethylene action. 2...
متن کاملMajor allergen from Amaranthus palmeri pollen is a profilin: Isolation, partial characterisation and IgE recognition.
BACKGROUND Pollens represent a rich source of proteins that are also potential elicitors of IgE-mediated pollen allergy. Sensitisation to panallergens could play an important role in diagnosis and specific immunotherapy, because these molecules are present in different plant pollens and plant foods and have marked structural similarity in different species. Profilins are one of the most common ...
متن کاملIdentification and characterization of a pan-allergen profilin, a major allergen from Caryota mitis pollen.
BACKGROUND Caryota mitis is a common plant in tropical and subtropical areas. It produces larger amount of pollen, which has great potential for allergenicity in the pollination season. OBJECTIVE This study aims to identify the components of Caryota mitis pollen contributing to human allergic diseases. METHODS The sera from 20 patients with a positive skin prick test to Caryota mitis pollen...
