von Willebrand factor (vWF) is synthesized by endothelial cells and stored in endothelium-specific granules, the Weibel-Palade (WP) bodies. The release of vWF from endothelial cells in vitro in response to secretagogues such as thrombin is considered to result in the loss of WP bodies through the fusion of the WP bodies with the plasma membrane.

Pathogenic gain-of-function variants in the genes encoding phosphoinositide 3-kinase δ (PI3Kδ) lead to accumulation of transitional B cells and senescent T cells, lymphadenopathy, and immune deficiency (activated PI3Kδ syndrome [APDS]). Knowing the genetic etiology of APDS afforded us the opportunity to explore PI3Kδ inhibition as a precision-medicine(More)
RATIONALE Patients with autoimmune lymphoproliferative syndrome (ALPS), a disorder of impaired lymphocyte apoptosis, often undergo radiographic chest imaging to evaluate the presence and progression of lymphadenopathy. These images often lead to parenchymal and interstitial lung findings of unclear clinical significance. OBJECTIVES To characterize the(More)
