Abstract:
Effective use of a TGF-.beta. antagonist to treat or to prevent loss of transplant function is described herein. Use of a TGF-.beta. antagonist is demonstrated to effectively prevent loss of organ function in a host due to chronic rejection in which TGF-.beta.-mediated fibroproliferation is a characteristic. Expression in situ of a TGF-.beta. antagonist in the form of a recombinant receptor, i.e., TGF-.beta. 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 hear in vertebrate hosts including human hosts.
Abstract:
Methods for assaying a donor lung for chronic allograft lung dysfunction (CLAD) optionally bronchiolitis obliterans syndrome (BOS) subtype or restrictive allograft syndrome (RAS) subtype of CLAD or risk of developing BOS subtype or RAS subtype CLAD post-transplant, the method comprising: a. measuring a normalized expression level of an RNA transcript of IL-6 or an expression product thereof in a sample of the donor lung pre-transplant or a normalized expression level of one or more S100 protein, optionally S100A8 and/or S100A9, polypeptide expression product in a sample from the donor lung post-transplant; b. assessing the likelihood of the donor lung developing BOS subtype CLAD or RAS subtype CLAD post-transplant based on said IL-6, S100, optionally S100A8 and/or S100A9, expression level wherein IL-6 expression level is positively correlated with an increased likelihood of developing BOS post-transplant, S100A8 expression level is positively correlated with having or having an increased likelihood of developing RAS and/or BOS subtype CLAD, and S100A9 is positively correlated with having and having an increased likelihood of developing RAS subtype CLAD.
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.
Abstract:
Método para clasificar un injerto pulmonar sometido a perfusión pulmonar ex vivo (PPEV) normotérmica, durante la perfusión y/o después de la perfusión, comprendiendo el método: a) recoger una muestra de ensayo del injerto pulmonar, en donde el injerto pulmonar es de un donante en muerte cardíaca (DMC); b) medir un nivel de polipéptido de un producto génico predictor de endotelina seleccionado de endotelina 1 (ET-1) y ET-1 grande en la muestra de ensayo; e c) identificar el injerto pulmonar como un buen candidato para trasplante o como un mal candidato para trasplante, en donde un nivel de polipéptido aumentado del producto génico predictor de endotelina en comparación con un control de pronóstico es indicativo de que el injerto es un mal candidato para trasplante.

Abstract:
A method of classifying a lung graft subjected to normothermic ex vivo lung perfusion (EVLP), during perfusion and/or after perfusion, the method comprising: a) collecting a test sample from the lung graft; b) measuring a polypeptide level of a negative transplant predictor gene product selected from CCG predictor gene products M-CSF, IL-8 SCGF-beta, GRO-alpha, G-CSF, MIP-1 alpha, and/or MIP-1beta, endothelin predictor gene products endothelin 1 (ET-1) and/or big ET-1, and/or apoptosis predictor gene products cytokeratin 18 (CK-18), caspase 3 and/or HMGB-1 in the sample and/or determining a metabolite profile of the sample for lung grafts that are from donors where the death was due to cardiac death (DCD); c) identifying the graft as a good candidate for transplant or a poor candidate for transplant wherein an increased polypeptide level of one or more negative transplant outcome predictor gene products compared to an outcome control or a reference metabolic profile is indicative the graft is a poor candidate for transplant.
