In T lymphocytes, the Wiskott-Aldrich Syndrome protein (WASP) and WASP-interacting-protein (WIP) regulate T cell antigen receptor (TCR) signaling, but their role in lymphoma is largely unknown. Here we show that the expression of WASP and WIP is frequently low or absent in anaplastic large cell lymphoma (ALCL) compared to other T cell lymphomas. In anaplastic lymphoma kinase-positive (ALK+) ALCL, WASP and WIP expression is regulated by ALK oncogenic activity via its downstream mediators STAT3 and C/EBP-β. Read More

Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is one of the leading global causes of virus-induced encephalitis. The infectious life-cycle of viruses is heavily dependent on the host membrane trafficking network. Here, we have performed a RNA-interference-based screen using a siRNA panel targeting 136 membrane trafficking proteins to identify the key regulators of JEV infection in HeLa cells. Read More

When activated by Wiskott-Aldrich syndrome proteins (WASP), Arp2/3 complex nucleates branched actin filaments important for processes like cellular motility and endocytosis . WASP-mediated activation of Arp2/3 complex requires a preformed actin filament, ensuring that activation by WASP creates branched instead of linear filaments. However, this biochemical requirement also means that assembly of branched actin networks must be primed with an initial seed filament [2-4]. Read More

WASH is an endosomal protein belonging to the Wiskott-Aldrich syndrome protein superfamily that participates in endosomal receptor trafficking by facilitating tubule fission via activation of the ubiquitously expressed Arp2/3 complex. While several studies have begun to understand the functions of WASH in cells lines, the in vivo function of WASH has not been fully elucidated since total body deletion in mice leads to early embryonic lethality. To circumvent this problem, we have used a WASH conditional knockout mouse model to investigate the role of WASH in the pancreas. Read More

Inflammatory bowel disease (IBD) is a chronic inflammatory condition caused by an aberrant immune response to microbial components of the gastrointestinal tract. Plasmacytoid dendritic cells (pDCs) are innate immune cells specialized in the production of type I interferons and were recently implicated in the pathogenesis of autoimmune disorders such as lupus and scleroderma. While pDCs were shown to infiltrate intestinal mucosa of IBD patients and proposed to participate in intestinal inflammation, their net contribution to the disease remains unclear. Read More

The Wiskott-Aldrich syndrome protein (WASp) is a key regulator of the actin cytoskeleton in hematopoietic cells and mutated in two severe immunodeficiency diseases with high incidence of cancer. Wiskott-Aldrich syndrome (WAS) is caused by loss-of-function mutations in WASp and most frequently associated with lymphoreticular tumors of poor prognosis. X-linked neuropenia (XLN) is caused by gain-of-function mutations in WASp and associated with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Read More

Purpose Of Review: Conventional gene therapy has been a successful, curative treatment modality for many primary immune deficiencies with significant improvements in the last decade. However, the risk of leukemic transformation with viral-mediated gene addition still remains, and unregulated gene addition is not an option for certain diseases in which the target gene is closely controlled. The recent bloom in genome modification platforms has created the opportunity to site-specifically correct mutated DNA base pairs or insert a corrective cDNA minigene while maintaining gene expression under control of endogenous regulatory elements.

Hyper IgE syndromes comprise a group of rare primary immunodeficiency disorders characterized by a triad of atopic dermatitis, recurrent skin and lung infections along with elevated IgE levels. Job syndrome or autosomal dominant hyper IgE syndrome because of heterozygous loss-of-function mutations with dominant negative effect in signal transducer and activator of transcription-3 is the prototype of these disorders. However, several other genetically characterized immunodeficiency disorders have been identified over the past decade and joined the umbrella of hyper IgE syndromes including autosomal recessive mutations in the DOCK8, ZNF431 and PGM3 genes and heterozygous mutations with dominant negative effect in the CARD11 gene.

Wiskott-Aldrich syndrome protein (WASP) activates the actin-related protein 2/3 homolog (Arp2/3) complex and regulates actin polymerization in a physiological setting. Cell division cycle 42 (Cdc42) is a key activator of WASP, which binds Cdc42 through a Cdc42/Rac-interactive binding (CRIB)-containing region that defines a subset of Cdc42 effectors. Here, using site-directed mutagenesis and binding affinity determination and kinetic assays, we report the results of an investigation into the energetic contributions of individual WASP residues to both the Cdc42-WASP binding interface and the kinetics of complex formation.

Hereditary spastic paraplegias (HSPs) are genetically diverse and clinically characterised by lower limb weakness and spasticity. The N471D and several other point mutations of human strumpellin (Str; also known as WASHC5), a member of the Wiskott-Aldrich syndrome protein and SCAR homologue (WASH) complex, have been shown to cause a form of HSP known as spastic paraplegia 8 (SPG8). To investigate the molecular functions of wild-type (WT) and N417D Str, we generated Str cells and ectopically expressed Str-GFP or Str-GFP in Str and WT cells. Read More

WIP (WASP interacting protein) together with N-WASP (neural Wiskott-Aldrich syndrome protein) regulates actin polymerization that is crucial for invadopodia and filopodia formation. Recently, we reported the WIP interaction with ITSN1 which is highly implicated in endo-/exocytosis, apoptosis, mitogenic signaling and cytoskeleton rearrangements.

The transition of hematopoiesis from the fetal liver (FL) to the bone marrow (BM) is incompletely characterized. We demonstrate that the Wiskott-Aldrich syndrome verprolin-homologous protein (WAVE) complex 2 is required for this transition, as complex degradation via deletion of its scaffold Hem-1 causes the premature exhaustion of neonatal BM hematopoietic stem cells (HSCs). This exhaustion of BM HSC is due to the failure of BM engraftment of Hem-1 FL HSCs, causing early death. Read More

WAS is a fatal X-linked combined immunodeficiency syndrome, the only cures for which are HSCT or gene therapy. AID occur in up to 72% of patients with WAS who do not receive HSCT, likely arising secondary to impaired multilineage immune autoregulatory function; AITD is not typically seen. In this article, we describe the case of a male patient who underwent HLA-matched HSCT for WAS at the age of 5 months, with his sister (a WAS carrier) acting as his donor and subsequently developed AITD 12 months post-transplant, with marked elevation of antithyroid peroxidase antibody titer.
