aspergillus fumigatus complement inhibitor: production, characterization, and purification by hydrophobic interaction and thin-layer chromatography.aspergillus fumigatus has previously been shown to produce a soluble extracellular inhibitor of the alternative complement pathway, called aspergillus complement inhibitor, or ci. we now report an efficient method for production of ci which relies on the fact that poorly conidiating cultures yielded ci activity with approximately sevenfold-higher potency than ci produced by conidiating cultures. ci from poorly conidiating cultures provided 50% inhibition of alternative pathway-mediated binding o ...19902228221
detection of aspergillus antigens associated with invasive infection.serial urine samples were collected from 33 neutropenic patients, 10 of whom developed invasive aspergillosis (ia) while undergoing bone marrow transplantation or remission induction therapy for leukemia. concentrated urine samples from the infected patients were subjected to polyacrylamide gel electrophoresis, blotted, and then incubated with antiserum raised to a cell wall extract of aspergillus fumigatus (anti-cw) or an immunoglobulin g monoclonal antibody to a. fumigatus galactomannan (eba1) ...19902229387
immunoblot analysis of sera from patients with allergic bronchopulmonary aspergillosis: correlation with disease activity.immunoblot analysis was used to evaluate the igg, ige, and iga responses to aspergillus fumigatus antigen with the sera of five patients with allergic bronchopulmonary aspergillosis (abpa) before, during, and after suspected exacerbation of their disease. the results revealed a heterogenous antibody response, unique for each patient, to specific aspergillus fumigatus antigens that correlated with the molecular weights of previously well-characterized antigens of importance in the immunopathogene ...19902229814
allergens as proteases: an aspergillus fumigatus proteinase directly induces human epithelial cell detachment.allergic bronchopulmonary aspergillosis (abpa) is characterized by pulmonary and systemic allergic and inflammatory processes triggered by fungal antigens. airway damage is a feature of this disorder, and although aspergillus-derived proteinases have been described, the capacity of aspergillus, however, to directly induce damage to human epithelium has not previously been studied. we therefore cultured aspergillus fumigatus from two patients with abpa, extracted mycelial products by sonication a ...19902229838
serum immunoglobulins e and g anti-aspergillus fumigatus antibody in patients with cystic fibrosis who have allergic bronchopulmonary aspergillosis.patients with cystic fibrosis frequently have pulmonary colonization with aspergillus fumigatus (af) and develop anti-af immunoglobulin e (ige) and igg antibodies. the diagnosis of allergic bronchopulmonary aspergillosis in subjects with cystic fibrosis is difficult because of the high incidence of af colonization, with development of humoral antibody responses. in this study, we sequentially measured serum anti-af ige (af-e) and igg (af-g) antibodies by elisa in subjects with cystic fibrosis. i ...19902230542
aspergillus fumigatus allergen i, a major ige-binding protein, is a member of the mitogillin family of cytotoxins.a major 18-kd ige-binding protein from aspergillus fumigatus (asp fi) has been purified. partial amino acid sequencing of asp f i showed extensive sequence homology (95%) between asp fi and a cytotoxin (mitogillin) produced by a. restrictus. crossinhibition radioimmunoassay using murine monoclonal antibody and human igg and ige antibodies showed that asp fi and mitogillin were antigenically indistinguishable. furthermore, both proteins inhibited protein synthesis in vitro by greater than 90%. as ...19902230656
