Introducción: especies de la familia Lauraceae son fuentes importantes de sustancias bioactivas, como las que actúan de insecticidas. En los estudios de bioprospección de lauraceas colombianas, a siete especies medicinales pertenecientes a esta familia se les evaluó su actividad acaricida frente a Dermatophagoides farinae y Blomia tropicalis, considerados como un problema en salud pública a nivel intradomiciliario. Objetivo: determinar la actividad acaricida de los extractos etanólicos de las especies de Lauraceae sobre los ácaros intradomiciliarios Dermatophagoides farinae y Blomia tropicalis, así como caracterizar los extractos obtenidos mediante ensayo fitoquímico preliminar. Métodos: la actividad acaricida in vitro de los extractos de las siete...

Blomia tropicalis, Dermatophagoides pteronyssinus and D. farinae are prevalent house dust mites. Concanavalin A-binding components derived from B. tropicalis (Bt-ConA extract) are highly immunogenic in allergic diseases. The aim of the present study was to evaluate the humoral and cellular immune responses to B. tropicalis in mite-sensitized patients. A total of 137 patients with allergic rhinitis with/without asthma and 109 non-atopic subjects were selected and analyzed by the skin prick test, and for total serum IgE and specific IgE levels to both Bt-total and Bt-ConA extracts, their proliferative response and cytokine (IFN-γ and IL-5) production by peripheral blood mononuclear cells (PBMC) stimulated with both extracts. Skin prick test showed that 70%...

Responses of IgE, IgG1, and IgG4 to concanavalin A-binding Blomia tropicalis antigens in allergic patients
Provedor de dados: 56
Autores: Almeida,K.C.; Silva,D.A.O.; Gennari-Cardoso,M.L.; Cunha-Júnior,J.P.; Alves,R.; Ynoue,L.H.; Resende,R.O.; Sung,S.J.; Taketomi,E.A.
Blomia tropicalis (Bt) and Dermatophagoides pteronyssinus (Dp) are the prevalent house dust mites in tropical countries and are associated with allergic diseases. Glycosylated antigens are highly immunogenic and involved in different pathologies. We evaluated the presence of IgE, IgG1, and IgG4 to concanavalin A-binding antigens (Bt-Con-A) isolated from Bt-total extract in sera of allergic and non-allergic subjects. Bt-total and Bt-Con-A extracts were evaluated by SDS-PAGE and ELISA for reacting with IgE, IgG1, and IgG4 in sera of 121 patients with allergic rhinitis and 36 non-allergic individuals. All subjects were skin prick tested with Bt-total extract and inhibition tests were performed for IgE, IgG1, and IgG4 using both extracts (Bt-total and...
