Project description:The transcriptomic response of Bacillus amyloliquefaciens FZB42 to maize root exudates at OD600=3.0. This is a comprehensive analysis using the data of six microarray experiments (Exp1-2-3 and ExpABC respectively, 18 hybridization in total).
Project description:Transcription profiling by array of Bacillus amyloliquefaciens strain FZB42 after interaction exudates (IE) treatment, at OD600=1.0 and at OD600=1.0 respectively. IE was the root exudates prepared from maize plants growing with FZB42. The reference was treated with the root exudates (RE), prepared from maize plants grown in an axenic system.
Project description:The effect of maize seed (Zea mays L. var. Surprise) exudates on Bacillus amyloliquefaciens FZB42 cultures grown to OD600 = 1.0 or 3.0 was tested against a negative seed exudate control sample.

Project description:Transcriptional profiling by array of Bacillus amyloliquefaciens FZB42 at log phase(OD600=1.0) and early stationary phase(OD600=3.0) after maize root exudate treatment of three concentrations(0.25mg/ml,0.50mg/ml,1.00mg/ml).

Project description:Transcription profiles of Bacillus amyloliquefacs FZB42 (cultured to an optical densit of 1.0 or 3.0) in response to root exudates from nutrient-sufficient maize plants and plants starved of nitrogen, phosphorus, potassium or iron.
Project description:The tolerogenic anti-CD3 monoclonal antibodies (anti-CD3) are promising compounds for the treatment of type 1 diabetes (T1D). Anti-CD3 administration induces transient T-cell depletion both in preclinical and in clinical studies. Notably, said depletion mainly affects CD4+ but not CD8+ T cells. Moreover, T1D reversal in preclinical models is accompanied by the selective expansion of CD4+FOXP3+ T regulatory (Treg) cells, which are fundamental for the long-term maintenance of anti-CD3-mediated tolerance. The mechanisms that lead to this immune-shaping by affecting mainly CD4+ T effector cells while sparing CD4+FOXP3+ Treg cells have still to be fully elucidated. This study shows that CD3 expression levels differ from one T-cell subset to another. CD4+FOXP3- T cells contain higher amounts of CD3 molecules than do CD4+FOXP3+ and CD8+ T cells both in mice and in humans. Said differences may explain the anti-CD3-mediated immune resetting that occurs in vivo after anti-CD3 administration in mice. In addition, transcriptome analysis demonstrates that CD4+FoxP3+ Treg cells are significantly less responsive than CD4+FoxP3- T cells to anti-CD3 treatment at molecular levels. Thus, heterogeneity in CD3 expression likely confers the various T-cell subsets differing susceptibility to in vivo tolerogenic anti-CD3-mediated modulation. This data sheds new light on the molecular mechanism that underlies anti-CD3-mediated immune resetting, and thus may open new opportunities to improve this promising treatment.
Project description:Rhizobium leguminosarum biovar viciae strain Rlv3841 was grown on a variety of compounds suspected of being in the rhizosphere and gene induction was compared to cells grown on either pyruvate NH4 or glucose NH4.
Project description:Rhizobium leguminosarum biovar viciae strain RU2386 was grown overnight on glc asp and the next day it was resuspended in glucose glutamate. Gene expression before resuspension was compared to the 2 h resuspended sample.
