    摘要: The present invention comprises artificial tissue constructs that serve as in vitro models of mammalian lung tissue. The artificial tissue constructs of the present invention comprise functionally equivalent in vitro tissue scaffolds that enable immunophysiological function of the lung. The constructs can serve as novel platforms for the study of lung diseases (e.g., interstitial lung diseases, fibrosis, influenza, RSV) as well as smoke- and smoking-related diseases. The artificial tissue constructs of the present invention comprise the two components of alveolar tissue, epithelial and endothelial cell layers.

    摘要: The invention is directed to co-culture systems comprising (i) rotating wall vessel (RWV)-cultured epithelial or differentiated tissue attached to microcarrier beads and (ii) the peripheral tissue equivalent (PTE) module of the MIMIC® system, and to methods of using the co-culture systems for assessing chemical or biological (bacterial or viral) insults. The system models mucosal exposure to chemicals, pathogens or antigen at various sites in the human body. The microcarrier and MIMIC® co-culture approach provides an in vitro co-culture model that simultaneously demonstrates mucosa-mediated antigen presentation and immunogenic responses. Models of the present invention can be used, for example, in assessments of disease pathogenesis and in pharmaceutical development, reproductive physiology, and immunological and toxicological evaluations. Models of the present invention can generate patient-specific localized mucosal immunology using primary cells, resembling the human physiological situation.

    摘要: Hemagglutination (HA) and hemagglutination inhibition (HAI) functional assays remain important instruments of analysis of virus-cell interaction and protecting efficacy of virus-specific antibodies and sera. However, they demonstrate limited sensitivity towards many viruses, and require significant volumes of viruses, erythrocytes, sera, and antibodies. The present invention comprises new and significantly more sensitive versions of the HA and HAI assays based on observing agglutination on activated surfaces of specifically opsonized plates and ELISA plates rather than in solution. A version of the new assay that uses ELISA plates additionally allows characterizing the affinity of functional antibodies in the tested sera and fluids, which is not possible in the classical HAI assay. The methods of the present invention can also be used to improve the sensitivity of agglutination methods based on latex beads and to develop agglutination methods using target cells other than erythrocytes.
