Project description:T-cell receptor (TCR) signaling is essential for the function of T cells and negatively regulated by the E3 ubiquitin-protein ligases CBL and CBLB. Here we combine mouse genetics and affinity purification coupled to quantitative mass spectrometry to monitor the dynamics of the CBL and CBLB signaling complexes that assemble in normal T cells over 600 seconds of TCR stimulation. We identify many previously known CBL and CBLB interacting partners, as well as a majority of proteins that have not yet been implicated in those signaling complexes. We exploit correlations in protein association with CBL and CBLB as a function of time of TCR stimulation for predicting the occurrence of direct physical association between them. The dataset is divided in two distinct subsets corresponding to the Cbl and to the Cblb interactomes. Each of them contains mass spectrometry results from the analysis of 10 different conditions of AP-MS purifications (based on affinity purification on Streptactin beads of One-Strep-tagged proteins) starting from CD4+ T cells which were either non stimulated or stimulated with anti-CD3 and anti-CD4 antibodies as follows: CBL interactome: - CBL-OST transgenic mice, CD4+ T cells non stimulated (noted Cbl_0) - CBL-OST transgenic mice, CD4+ T cells stimulated 30s (noted Cbl_30) - CBL-OST transgenic mice, CD4+ T cells stimulated 120s (noted Cbl_120) - CBL-OST transgenic mice, CD4+ T cells stimulated 300s (noted Cbl_300) - CBL-OST transgenic mice, CD4+ T cells stimulated 600s (noted Cbl_600) - WT mice, CD4+ T cells non stimulated (noted WT_0) - WT mice, CD4+ T cells stimulated 30s (noted WT_30) - WT mice, CD4+ T cells stimulated 120s (noted WT_120) - WT mice, CD4+ T cells stimulated 300s (noted WT_300) - WT mice, CD4+ T cells stimulated 600s (noted WT_600) For the CBL interactome, 3 biological replicates were prepared for these 10 different conditions (noted Ech1, Ech2, Ech3), yielding 30 analyzed samples. Three technical nanoLC-MS runs were acquired for each sample (noted R1, R2, R3), leading to 90 nanoLC-MS raw files. CBL interactome: - CBLB-OST transgenic mice, CD4+ T cells non stimulated (noted Cblb_0) - CBLB-OST transgenic mice, CD4+ T cells stimulated 30s (noted Cblb_30) - CBLB-OST transgenic mice, CD4+ T cells stimulated 120s (noted Cblb_120) - CBLB-OST transgenic mice, CD4+ T cells stimulated 300s (noted Cblb_300) - CBL-OST transgenic mice, CD4+ T cells stimulated 600s (noted Cblb_600) - WT mice, CD4+ T cells non stimulated (noted WT_0) - WT mice, CD4+ T cells stimulated 30s (noted WT_30) - WT mice, CD4+ T cells stimulated 120s (noted WT_120) - WT mice, CD4+ T cells stimulated 300s (noted WT_300) - WT mice, CD4+ T cells stimulated 600s (noted WT_600) For the CBLB interactome, 4 biological replicates were prepared for these 10 different conditions (noted S1, S2, S3, S4), yielding 40 analyzed samples. For series S1 to S3, 2 technical nanoLC-MS runs were acquired for each sample (noted R1, R2) and for serie S4, 3 technical nanoLC-MS runs were acquired for each sample (noted R1, R2, R3), leading in total to 90 nanoLC-MS raw files.

Project description:Organoid grown from intestinal crypts of Cbl flox/flox; Cbl-bflox/flox; R26Cre ERT2 mice were in presence or absence of 4-hydroxy-tamoxifen to delete Cbl and Cblb. Single cell RNA sequencing were performed in these two conditions to undestand the change in cell populations due to Cbl and Cblb depeletion.

Project description:Fungal infections claim an estimated 1.5 million lives every year. Mechanisms that protect from fungal infections are still elusive. Recognition of fungal pathogens relies on C-type lectin receptors (CLR) and their downstream signaling kinase SYK. Here we report that the E3-ubiquitin-ligase CBL-B controls proximal C-type lectin receptor signaling in macrophages and dendritic cells. We show that CBL-B associates with SYK and ubiquitinates SYK, Dectin-1, and Dectin-2 upon fungal recognition. Functionally, CBL-B deficiency results in increased inflammasome activation, enhanced reactive oxygen species production, and increased fungal killing. Genetic deletion of Cblb protects mice from morbidity caused by cutaneous infection and markedly improves survival upon a lethal systemic infection with Candida albicans. Based on these findings, we engineered a cell-permeable CBL-B inhibitory peptide that protects mice from lethal C. albicans infections. We thus describe a key role for Cblb in the regulation of innate anti-fungal immunity and establish a novel paradigm for the treatment of fungal sepsis.

Project description:Cbl (Casitas B-lineage lymphoma) is a prominent post-translational regulator of protein tyrosine kinases (PTKs) that targets activated receptors for ubiquitination-mediated degradation. However, mutations within its E3 ubiquitin ligase activity rendering RING domain are often not sufficient to induce transformation. Rather, a conserved residue (Y371) within the linker helix region (LHR) of Cbl has been a mutational hotspot in myeloproliferative diseases. Interestingly, phosphorylation of Y371 is a prerequisite for Cbl’s ability to ubiquitinate PTKs. We have previously shown that Y371 mutations affect the conformation of Cbl that can be related to its transformation potential. We wanted to investigate for any additional advantage that the Cbl-Y371 mutants could gain over their wild-type counterpart so as to explain their oncogenicity. In our current study, we wanted to investigate the transcriptome profiles of cells overexpressing WT CBL or CBL-70Z, a well-characterized oncogenic CBL mutant lacking residues 366-382 and Y371S a prevalent MDS/MPN CBL mutant. We found an interesting inverse correlationship between the transcriptome of cells expressing WT CBL and the mutant CBLs. The results from this study can be linked to the oncogenic abilities of the mutant CBLs.

Any divergent interacting abilities between the two can be used to decipher the mechanism by which the mutants elicit oncogenic transformation.

Project description:In order to further explore the miRNAs expression in WT and Cbl-b-/- CD4+ T cells, we used anti-CD3 to activate CD4+ T cells, and then used microarray to detect the expression of miRNAs in unactivated and activated T cells from WT and Cbl-b-/- mice. The results showed that there were different expression of miRNAs in WT and Cbl-b-/- CD4+ T cells when activated or not.

Project description:Expression of genes that are differentially expressed between c-Cbl control and c-Cbl mutant hematopoietic stem and progenitor cells were identified through this approach. Interestingly, several leukemia associated genes, particularly transcription factors, were differentially expressed between c-Cbl WT and c-Cbl mutant hematopoietic stem and progenitor cells. Hematopoietic stem and progenitor cells of c-Cbl control and c-Cbl mutant mice were sorted based on their defined immunophenotype. Gene expression studies were performed using Illumina microarray chips.
