  • Publication number: 20150376723
    Abstract: Described are biomarkers and associated methods for identifying a subject having, or at risk of developing, severe illness from influenza. The level of one or more biomarkers in a test sample from the subject is determined and compared to a control level. Optionally, the subject has or is suspected of having H1N1 influenza. In some embodiments the biomarkers may include IL23R, IL10, TNFRSF13B, CX3CR1, CCR2, MAP2K3 and/or IRF1. In some embodiments, the biomarkers include a combination of IL2 and IL23R or IL10 and IL23R. Also described are methods which include determining the level of two or more biomarkers in a sample and multivariate methods are used for comparing the levels in the test sample to the level in a control sample.

  • Publication number: 20130029873
    Abstract: A method for determining pulmonary fibrosis subtype and/or prognosis in a subject having pulmonary fibrosis comprising: a. determining an expression profile by measuring the gene expression levels of a plurality of genes selected from genes listed in Table 1, 2, 3, 4 7, 8, 9, and/or 10, in a sample from the subject; and b. classifying the subject as having a good prognosis or a poor prognosis based on the expression profile; wherein a good prognosis predicts decreased risk of post lung transplant primary graft dysfunction, and wherein a poor prognosis predicts an increased risk of post lung transplant primary graft dysfunction.

  • Publication number: 20090263389
    Abstract: Effective use of a TGF-? antagonist to treat or to prevent loss of transplant function is described herein. Use of a TGF-? antagonist is demonstrated to effectively prevent loss of organ function in a host due to chronic rejection in which TGF-?-mediated fibroproliferation is a characteristic. Expression in situ of a TGF-? antagonist in the form of a recombinant receptor, i.e., TGF-? type III receptor (TGFBIIIR) showed prevention of bronchiolitis obliterans in comparison to untreated controls in a rat lung transplant model. This provides an effective method for preventing or inhibiting chronic rejection of transplant organs such as lung, kidney, liver and heart in vertebrate hosts including human hosts.
