Abstract
Asthma, a respiratory tract disease, is characterized by inflammation and obstruction of airway. Inflammatory cells play a significant role in allergic asthma, and there is no complete cure for asthma. One of the new approaches in medicines is nanoparticle-base treatment. The aim of the current study is to introduce a new therapeutic approach in nano-medicine with neurotensin. Conjugated peptide nanoparticles were prepared and characterized, and then administrated to asthmatic mice. Airway hyperresponsiveness (AHR) test, broncho-alveolar lavage fluid (BALF) cells counting, cytokines level, and histopathology study were conducted. Treatment with peptide nanoparticles could control AHR, percentage of eosinophils in BALF, levels of interleukin 4 (IL-4), IL-5, and IL-33, peri-airways and perivascular eosinophilic inflammation. Producing and using of new peptide nano-drugs could introduce new therapeutic approach in controlling pathological-related mechanisms in allergic asthma.
期刊介绍：
Founded in 1972 by Professor A. Oehling, Allergologia et Immunopathologia is a forum for those working in the field of pediatric asthma, allergy and immunology. Manuscripts related to clinical, epidemiological and experimental allergy and immunopathology related to childhood will be considered for publication. Allergologia et Immunopathologia is the official journal of the Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) and also of the Latin American Society of Immunodeficiencies (LASID). It has and independent international Editorial Committee which submits received papers for peer-reviewing by international experts. The journal accepts original and review articles from all over the world, together with consensus statements from the aforementioned societies. Occasionally, the opinion of an expert on a burning topic is published in the "Point of View" section. Letters to the Editor on previously published papers are welcomed. Allergologia et Immunopathologia publishes 6 issues per year and is included in the major databases such as Pubmed, Scopus, Web of Knowledge, etc.
