Wasp sting is a relatively common arthropod assault. This usually results in pain and mild allergic reactions, but sometimes may cause severe systemic reaction and multiorgan dysfunction including rhabdomyolysis, hemolysis, coagulopathy, hepatic, renal and cardiac complications. Along with several other pathomechanisms, rhabdomyolysis is a distinguished cause of acute kidney injury (AKI) in pa...

Background: Wasp stings are quite commonly observed in Bangladesh though they are under reported. However, rhabdomyolysis following multiple wasp stings is a rare entity. Case report: A middle aged physician was stung by a swarm of wasps at multiple sites of the body. He felt severe pain at the sites of the stings and was primarily treated with intravenous hydrocortisone and chlorpheniramine. W...

Cdc42 is a key regulator of the actin cytoskeleton and activator of Wiskott-Aldrich syndrome protein (WASP). Although several studies have separately demonstrated the requirement for both Cdc42 and WASP in Fc receptor (Fc R)-mediated phagocytosis, their precise roles in the signal cascade leading to engulfment are still unclear. Reduction of endogenous Cdc42 expression by using RNA-mediated int...

Cdc42 is a key regulator of the actin cytoskeleton and activator of Wiskott-Aldrich syndrome protein (WASP). Although several studies have separately demonstrated the requirement for both Cdc42 and WASP in Fc(gamma) receptor (Fc(gamma)R)-mediated phagocytosis, their precise roles in the signal cascade leading to engulfment are still unclear.

Wiskott-Aldrich Syndrome protein (WASP) integrates cell signaling pathways to the actin cytoskeleton, which play a critical role in T-cell activation and migration. Hematopoietic cells express both WASP and neural-WASP (N-WASP) which share similar domain structure, yet WASP deficiency causes Wiskott-Aldrich syndrome, suggesting that N-WASP present in the cells is not able to carry out all the f...

The Wiskott-Aldrich syndrome (WAS) is an X-linked primary immunodeficiency disease, arising from mutations of the WAS-protein (WASP) gene. Previously, we have reported that mononuclear cells from WAS patients showed lack/reduced of the intracellular WASP (WASP(dim)) by flow cytometric analysis, and analysis of WASP by flow cytometry (FCM-WASP) was useful for WAS diagnosis. In this study, we rep...

Involvement of the Wiskott-Aldrich syndrome protein (WASp) in promoting cell activation requires its release from autoinhibitory structural constraints and has been attributed to WASp association with activated cdc42. Here, however, we show that T cell development and T cell receptor (TCR)-induced proliferation and actin polymerization proceed normally in WASp-/- mice expressing a WASp transgen...

We report on a 6 year old patient with an unusual clinical presentation of WAS and oligoclonal proliferation of TCR+ large granular lymphocytes (LGL). Flow cytometry demonstrated two distinct populations of lymphocytes with strongly decreased (WASP-) or normal expression levels of WASP (WASP+), respectively. Molecular analysis confirmed a splice site mutation in intron 2 of the WASP gene in the...
