Project description:To determine the global gene occupancy by Wiskott - Aldrich syndrome Protein (WASP) we perform ChIP-seq assay in two lymphoblastoid cell lines. We identify WASP-enriched genes, including several WASP-interaction genes previously reported; in addition, our results suggest the implication of WASP in diverse cellular process

Project description:To investigate a role of nuclear WASp in T cell development we performed WASp chromatin immunoprecipitation and deep sequencing (ChIP-Seq) in thymocytes and spleen CD4+ T cells. To pre-process raw ChIP-Seq data, the total number of reads were normalized and aligned against the mouse genome. WASp was enriched at transcription start sites of a large number of protein-coding genes. Many of the WASp-enriched genes were associated with RNA Polymerase II-enriched genes and active epigenetic marks of transcription; H3K4m3, H3K9a, H3K27a, and with the epigenetic mark for active enhancers H3K4m1. To study the distribution of overactive WASpI296T in the thymocyte genome and to identify regions enriched in WASpI296T binding, we performed second round of ChIP-Seq analysis using the WASp F-8 antibody. To detect differences in gene enrichment between thymocytes expressing wildtype WASp or WASpI296T, we applied stringent conditions and subtracted common genes between the two samples. Using this approach, we identify 70 WASpI296T-enriched genes. Functional clustering of these genes revealed that WASpI296T was associated with RNA Polymerase II genes in 11 functional groups of genes.thymocytes and spleen CD4+ T cells. WASp was enriched at transcription start sites of a large number of protein-coding genes.

Project description:Mutations in the immune-specific actin regulator WASp induce a proinflammatory state in myeloid cells, whose underlying causes remain poorly defined. Here, we applied microfabricated tools that mimic tissue mechanical forces to explore the role of WASp in connecting mechano-sensing to the activation of inflammatory responses in macrophages. We show that WASp-deficient macrophages carry nuclear structure alterations and undergo increased blebbing and nuclear rupture when exposed to mechanical confinement. High-resolution imaging indicates that WASp drives the formation of protective perinuclear actin structures in response to confinement. Functionally, WASp null macrophages respond to mechanical confinement by inducing a transcriptional profile consistent with the release of immunogenic DNA in the cytosol. The proinflammatory state of mechanically confined WASp-deficient macrophages depends, in part, on the cGAS-STING pathway of cytosolic DNA sensing. Together, these data uncover a WASp-dependent mechanism to restrict activation of inflammatory signalling in tissue macrophages and provide hints to target unabated inflammation in Wiskott-Aldrich Syndrome.

Project description:Phagocytosis requires the activation of a plethora of mechanisms that include the activation of the actin cytoskeleton guided by the Arp2/3 complex. These are promoted by activators such as the Wiskott Aldrich Syndrome Protein (WASP) family members. In order to further understand the molecular mechanisms involved in the early events leading the phagocytosis of the pathogenic Mycobacterium tuberculosis, we set out to examine potential roles of miRNAs in phagocytosis using genome-wide expression profiling to identify miRNAs differentially regulated following mycobacterial infection. One of the miRNAs activated upon infection of mouse macrophages with the non-pathogenic Mycobacterium smegmatis, the widely conserved miR-142-3p, was predicted and confirmed to target the Neural-WASP (N-WASP). Upregulating of miR-142-3p in mouse macrophages inversely correlated with levels of N-WASP, upon infection with live pathogenic and non-pathogenic mycobacteria, suggesting an active role of Mycobacterium tuberculosis on the regulation of phagocytosis, at the post-transcriptional level, in host cells. The reduction of N-WASP correlated with a reduced internalization of bacteria per macrophage, independently of the phagocytosis index. Furthermore, the downregulation of WASP levels accompanied those of N-WASP, at early but not at late time points, suggesting a closely regulatory mechanism among both family members, dependent on the time frame of the phagocytosis. Additionally, upregulating of miR-142-3p promoted the change in the protein levels of another predicted and confirmed target, the Cofilin2 protein, in a phagocytosis-independent fashion. Downregulation experiments promoted aberrant morphologic phenotypes in macrophages, similar to observed by others in PBMCs of humans with Wiskott Aldrich Syndrome, suggesting the strong involvement of miR-142-3p on the regulation of the actin machinery in macrophages. Altogether these results show for the first time that miRNAs are involved in the regulation of actin-mediated phagocytosis of pathogenic bacteria and that these are direct targets of Mycobacterium tuberculosis.
