In a sample of 190 Costa Rican allergic patients and 100 non atopic subjects there was a positive correlation of positivities in skin prick tests to individual Poaceae species and to the Tribe. The exceptions were Panicum maximun, Panicum molle, and Holcus lanatus, because they presented higher

Group V grass pollen allergens belong to the major grass pollen allergens causing reactions of type I allergy. cDNAs coding for two isoforms of the group V allergen of velvet grass pollen (Holcus lanatus), a widespread grass species, were isolated from a cDNA library by hybridization with a

Decreased arsenate [As(V)] uptake is the major mechanism of naturally selected As(V) hypertolerance in plants. However, As(V)-hypertolerant ecotypes also show enhanced rates of phytochelatin (PC) accumulation, suggesting that improved sequestration might additionally contribute to the hypertolerance

The knowledge of IgE-binding epitopes on allergen molecules is important for better understanding allergen-antibody interactions and, thus, for developing new strategies for immunotherapy. Our purpose was to more precisely define the number and structure of IgE-binding epitopes of a paradigmatic

BACKGROUND Grass pollen extracts are complex mixtures consisting of different major allergenic and non-allergenic components. Phl p 4 is an important allergen, because more than 75% of grass pollen allergic patients produce specific IgE antibodies against group 4 allergens. OBJECTIVE This study was

A 4-year-old boy was admitted to our department with fever, cough and dyspnoea, unresponsive to salbutamol and antibiotic therapy. He had previously contracted bronchiolitis at 20 days of life, followed by intermittent episodes of wheeze that never required hospitalisation and responded to short
