Expression profile of maizes stalk challenged with the corn borer Sesamia nonagrioides
  • organism-icon Zea mays
  • sample-icon 8 Downloadable Samples
  • Technology Badge Icon Affymetrix Maize Genome Array (maize)

Description

Stalk borers are major pests for some of the most important crops in the world, such as maize or rice. Plant defense mechanisms against these herbivores have been poorly investigated. The maizes stalk responds to insect feeding activating defense genes including hormone biosynthetic-related or proteinase inhibitor transcripts. The most outstanding conclusion is that cells in the maizes stalk undergo cell wall fortification after corn borer tunneling.

Transciptomic analysis of maize response to the attack of Sesamia nonagrioides
  • organism-icon Zea mays
  • sample-icon 12 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

We performed a transcriptomic analysis to identify genes differentially transcribed in the maize stem upon corn borer feeding and treatment with insects regurgitates by using the MACE (Massive Analysis of cDNA Ends) technology. Overall design: Two comparisons were performed: Insect chewing vs control and Regurgitate+wounding vs wounding in three biological replicates per treatment

Effect of BCL11B overexpression on transcriptome of T-cell acute lymphoblastic leukemia (T-ALL) cells
  • organism-icon Homo sapiens
  • sample-icon 6 Downloadable Samples
  • Technology Badge IconNextSeq 500

Description

To investigate the effects of BCL11B on T-cell differentiation, we performed gain of function studies in cells with a T-lineage differentiation arrest, namely T-ALL cells. Gene expression profiling by RNA-Seq demonstrated that BCL11B overexpression induced transcriptional changes consistent with T-cell differentiation as early as 72 hours after transduction, indicating a rapid regulatory effect of BCL11B on the T-lineage transcriptional program and supporting an important role for BCL11B in human T-cell differentiation. Overall design: T-ALL cells were transduced with a BCL11B-GFP expression vector (overexpressing cells) or an empty GFP vector (control cells). GFP+ cells were isolated by fluorescence activation cell sorting (FACS) at 72 hours post transduction and analyzed by RNA-Seq to determine the effect of BCL11B on the transcriptome of T-ALL cells.

Publication Title

The T-ALL related gene BCL11B regulates the initial stages of human T-cell differentiation.

Gene expression changes induced by dimerization of intracellular c-Mpl in cord blood CD34+ progenitors
  • organism-icon Homo sapiens
  • sample-icon 11 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Homodimerization of Mpl can also be accomplished in the absence of Tpo, by binding of a synthetic ligand (Chemical inducer of dimerization, CID) to a constitutively expressed fusion protein F36VMpl consisting of a ligand binding domain (F36V) and the intracellular signaling domain of Mpl. In contrast to Tpo stimulation, F36VMpl dimerization in human CD34+ progenitor cells generates robust erythropoiesis.

Publication Title

Novel pathways to erythropoiesis induced by dimerization of intracellular C-Mpl in human hematopoietic progenitors.

Gene expression profiling of skin melanophages and macrophages positive or negative for MHC class II expression
  • organism-icon Mus musculus
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

The lack of mouse models permitting the specific ablation of tissue-resident macrophages and monocyte-derived cells complicates understanding of their contribution to tissue integrity and to immune responses. Here we use a new model permitting diphtheria-toxin (DT)-mediated depletion of those cells and in which dendritic cells are spared. We showed that the myeloid cells of the mouse ear skin dermis are dominated by a population of melanin-laden macrophages, called melanophages, that has been missed in most previous studies. By using gene expression profiling, DT-mediated ablation and parabiosis, we determined their identity including their similarity to other skin macrophages, their origin and their dynamics. Limited information exist on the identity of the skin cells responsible for long-term tattoo persistence. Benefiting of our knowledge on melanophages, we showed that they are responsible for retaining tattoo pigment particles through a dynamic process which characterization has direct implications for improving strategies aiming at removing tattoos.

Unveiling skin macrophage dynamics explains both tattoo persistence and strenuous removal.

Proliferating Langerhans cells dampen inflammation in established mouse psoriatic lesions
  • organism-icon Mus musculus
  • sample-icon 48 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Gene 1.0 ST Array (mogene10st)

Description

Psoriasis is a chronic inflammatory skin disease of unknown etiology. Although macrophages and dendritic cells (DCs) have been proposed to drive the psoriatic cascade, their largely overlapping phenotype hampered studying their respective role. Topical application of Imiquimod, a Toll-like receptor 7 agonist, induces psoriasis in patients and psoriasiform inflammation in mice. We showed that daily application of Imiquimod for 14 days recapitulated both the initiation and the maintenance phase of psoriasis. Based on our ability to discriminate Langerhans cells (LCs), conventional DCs, monocytes, monocyte-derived DCs and macrophages in the skin, we characterized their dynamics during both phases of psoriasis. During the initiation phase, neutrophils infiltrated the epidermis whereas monocytes and monocyte-derived DCs were predominant in the dermis. During the maintenance phase, LCs and macrophage numbers increased in the epidermis and dermis, respectively. LC expansion resulted from local proliferation, a conclusion supported by transcriptional analysis. Continuous depletion of LCs during the course of Imiquimod treatment aggravated chronic psoriatic symptoms as documented by an increased influx of neutrophils and a stronger inflammation. Therefore, by developing a mouse model that mimics the human disease more accurately, we established that LCs play a negative regulatory role during the maintenance phase of psoriasis.
