In this issue of the Jornal de Pediatria, Geraldini et al. attempt to add another piece to the puzzle in order to provide additional insight into ocular symptoms associated with allergies. They used a validated instrument that focuses on the adolescent population in school with more than three episodes of ocular itching, who are more likely to have allergic rather than infectious etiologies, al...
BACKGROUND Profilins are small eukaryotic proteins involved in modulating the assembly of actin microfilaments in the cytoplasm. They are able to bind both phosphatidylinositol-4,5-bisphosphate and poly-L-proline (PLP) and thus play a critical role in signaling pathways. Plant profilins are of interest because immunological cross-reactivity between pollen and human profilin may be the cause of ...
BACKGROUND Sublingual immunotherapy (SLIT) is a relatively new form of treatment for type I allergies and a good safety profile is rapidly being established. Evidence on the efficacy of SLIT is increasing, and the present study provides further supportive data. We describe the results of treatment with a SLIT vaccine formulated with a range of allergen extracts obtained by allergologists in dai...
آلرژی غذایی نوعی پاسخ غیر طبیعی نسبت به یک ماده غذایی بوده که بدن آن را مضر تلقی می نماید. بعبارت دیگر آلرژی غذایی شرایط خاص فیزیولوژیکی است که با سیستم ایمنی بدن دخالت دارد.
Understanding the fate of proteins during digestion is of especial relevance to understanding the basis of food allergies. Little is known of the immunological mechanisms involved in the sensitisation of an individual towards a food and, with the exception of the fruit and vegetable allergies (which appear to be secondary responses to tree and weed pollen allergies), it is thought that food all...
Ploidy level is one of important factors for plant breeders; therefore models that can predict it are very practical. To estimate of ploidy levels in some species, hybrids and cultivars of Rosa, dimensions of over 500 pollens include pollen length, width and area measured at ABRII. The calculations were carried out in several stages. First, Ploidy levels were regressed with pollen dimensions, a...
Allergic reactions to tree nuts can be serious and life threatening. Considerable research has been conducted in recent years in an attempt to characterize those allergens that are most responsible for allergy sensitization and triggering. Both native and recombinant nut allergens have been identified and characterized and, for some, the IgE-reactive epitopes described. Some allergens, such as ...
FOXP3+ regulatory T cells (Tregs) maintain tolerance against self-antigens and innocuous environmental antigens. However, it is still unknown whether Treg-mediated tolerance is antigen specific and how Treg specificity contributes to the selective loss of tolerance, as observed in human immunopathologies such as allergies. Here, we used antigen-reactive T cell enrichment to identify antigen-spe...
Rice is the major staple food in a large part of the world, especially in Asia. Hypersensitivity reactions to rice are rare. Moreover, cases of occupational allergies induced by inhalation of rice powder are uncommon. We report a 31-year-old male with work-related rhinitis and conjunctivitis symptoms caused by occupational exposure to rice powder in the grain industry. He showed positive respon...
