Abstract:
Pneumonia due to the fungus Pneumocystis jirovecii is a life-threatening infection that occurs in immunocompromised patients. The inability to culture the organism as well as the lack of a sequenced genome has hindered antigen discovery that could be useful in developing effective vaccines, therapeutic antibodies and diagnostic methods. A method of surface proteomics of Pneumocystis murina that reliably detects surface proteins that are conserved in Pneumocystis jirovecii is described. In particular, eight identified P. murina surface proteins are described, including MeulO, GSC-1, Ght5, Erg6, ATP2, Gas4, and Mfsl. Methods of eliciting immune responses against the identified proteins, generating therapeutic antibodies against the identified proteins, as well as diagnostic methods based on the identified peptides are described.
Abstract:
The invention relates to of analyzing vector supernatants useful for transducing T cells destined for administration to a human subject. The invention also related to methods of analyzing transduced T cells destined for administration to a human subject. The invention provides a method of analyzing a genetically modified T cell to detect a contaminant, wherein the genetically modified T cell comprises a nucleic acid encoding a chimeric antigen receptor (CAR), wherein the CAR comprises an antigen binding domain, a transmembrane' domain, a costimulatory signaling region, and a signaling domain. In one embodiment, the contaminant is at least one selected from the group consisting of endotoxin, mycoplasma, replication competent lentivirus (RCL), p24, VSV-G nucleic acid, HN gag, residual anti-CD3/anti-CD28 coated beads, mouse antibodies, pooled human serum, bovine serum albumin, bovine serum, culture media components, vector packaging cell or plasmid components, a bacterium and a fungus.
Abstract:
La présente invention concerne une méthode de diagnostic in vitro d'une infection fongique invasive par spectrométrie de masse MALDI-TOF. Selon l'invention, -on fournit un échantillon d'un liquide biologique provenant d'un mammifère, ledit liquide biologique contenant notamment, des protéines et/ou des lipides et/ou des sels et/ou des polysaccharides et/ou des oligosaccharides et/ou des monosaccharides susceptibles de former des complexes avec lesdites protéines et/ou lipides et/ou sels; -on traite ledit échantillon de liquide biologique de manière à extraire lesdits polysaccharides et/ou oligosaccharides et/ou monosaccharides; -on détermine par spectrométrie de masse de type MALDI-TOF la présence ou non, parmi lesdits les polysaccharides, oligosaccharides et/ou monosaccharides extraits, d'au moins un composé d'intérêt donné provenant dudit micro-organisme fongique et choisi parmi les polysaccharides, les oligosaccharides et les monosaccharides; -on en déduit que si ledit composé d'intérêt donné est présent dans ledit échantillon, ledit mammifère est atteint d'une infection fongique invasive.
Abstract:
A method and composition for extracting an analyte from a test sample such as grain, so as to determine whether the test sample is contaminated with a toxin. The method is particularly useful for detecting the presence in a batch of grain of a mycotoxin, such as for example aflatoxin, ochratoxin, T2, zearalanone, vomitoxin (deoxynivalenol a/k/a DON), patulin and fumonisin. Extraction is performed with use of a composition that includes a proteinaceous material, such as albumin, as an extraction agent.

Abstract:
The present invention describes the use of enzymes having D-arabinitol oxidase activity with the concomitant generation of hydrogen peroxide for the diagnosis of fungal infections of humans and other organisms, and for the detection of fungal organisms that are present on or in surfaces or permeable materials. The present invention also describes methods and kits for the detection of fungi, and the diagnosis of fungal infections based upon D-arabinitol oxidase activity. The present invention also provides a new biochemical activity for gene products encoded by bacterial genes previously identified only with putative function. Activity of these gene products includes the ability to oxidize D-arabinitol with the concomitant generation of hydrogen peroxide.
