摘要:
A method for keeping leukocytes alive ex vivo or in vitro, comprising maintaining the leukocytes in a medium comprising from 3 to 10 mM of glucose, in hypoxic conditions with P(O 2 ) ≤ 10 mM Hg.
摘要:
The present invention relates to an in vitro method of culturing a segmented filamentous bacterium strain, comprising co-culturing said segmented filamentous bacterium strain with a eukaryotic host cell, wherein the culture is performed at an O2 level inferior to 5% in a rich tissue culture liquid medium containing bacterial medium components including iron. The present invention also relates to methods for genetically modifying a segmented filamentous bacterium strain comprising a step a culturing the strain in vitro.
摘要:
The present invention relates to compositions and methods for blocking entry of Shigella into a cell of an animal, to therefore providing protection against, or reduce the severity of Shigella infections. More particularly it relates to the use of the IpaD protein obtained from natural sources and/or through synthesis or recombinant technology, and conjugates thereof to induce neutralizing antibodies having protective activity against several serotypes of Shigella, in particular S. flexneri. The composition of the invention is useful to prevent and/or treat shigellosis caused by a bacterium of the Shigella family.
摘要:
The invention relates to a double-stranded polynucleotide comprising on its positive strand considered from its 5' end to its 3' end, (i) a promoter of a gene of interest or several promoters of various genes of interest selected among genes which are endogenous to a determined cell, and, (ii) one or several barcode(s) wherein each barcode contains at least one barcode unit formed of at least one, especially of multiple, recognition binding sites each binding site being composed of a nucleotide sequence, and wherein each of said barcode(s) is under the control of at least one of said promoter(s) for transcription. It further concerns use of said polynucleotide to monitor gene expression patterns in living cells, especially in single cells, with a rapid and high spatio-temporal resolution.
摘要:
The present invention relates to compounds derived from sugars which reproduce the epitopes of Shigella flexneri serotypes 3a and X and to the use thereof for the preparation of vaccine compositions. More specifically, the subject matter of the present invention relates to novel glycoconjugated compounds comprising oligosaccharides or polysaccharides described hereinafter, to the method for synthesizing these oligosaccharides or polysaccharides and glycoconjugates, to derivatives of these oligosaccharides or polysaccharides, to compositions containing same, and also to the use of the glycoconjugates for vaccination purposes. Finally, the present invention relates to methods for diagnosing a Shigella flexneri infection using one or more oligosaccharides or polysaccharides or conjugates thereof.
摘要:
The ospF gene of Shigella flexneri encodes a phosphatase, which is a member of a new class of phosphatases. The OspF phosphatase inhibits the activity of several proteins either by direct protein modification or transcription downregulation. These proteins include MAP kinase, IL-8, CCL20, IL-12, AP1, CREB, RPA p32, and BCL2 related proteins. Methods for treating diseases using OspF phosphatase, methods for identifying agents that modulate OspF phosphatase's activity, methods for identifying agents that mimic OspF phosphatase's activity, and immunogenic compositions comprising OspF phosphatase are provided. A strain of Shigella flexneri containing an inactivated ospF gene is also provided.
摘要:
The present invention relates to a saccharide selected from the group consisting of: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ{B(E)CD} €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ{(E)CDAB}n €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ{AB(E)CD}n Wherein A, B, C, E, D and n are as defined in claim 1. The invention also relates to derivatives thereof, pharmaceutical compositions comprising said derivatives, and kit for the diagnostic of Shigella flexneri type 2a infection comprising said derivatives.
摘要:
The invention provides methods of using CARD-4 molecules to screen for modulators of LPS-induced cell signaling pathways. Also included are CARD-4 deficient mice, methods of modulating LPS-induced cell signaling pathways, and methods of treating or preventing bacterial infections.
