Pulmonary alveolar proteinosis (PAP) is a rare lung disorder in which surfactant-derived lipoproteins accumulate excessively within pulmonary alveoli, causing severe respiratory distress. The importance of granulocyte/macrophage colony-stimulating factor (GM-CSF) in the pathogenesis of PAP has been confirmed in humans and mice, wherein GM-CSF signaling is(More)
The inflammatory cytokine interleukin (IL)-17 is involved in the pathogenesis of allergic diseases. However, the identity and functions of IL-17-producing T cells during the pathogenesis of allergic diseases remain unclear. Here, we report a novel subset of T(H)2 memory/effector cells that coexpress the transcription factors GATA3 and RORγt and coproduce(More)
Monthly intravenous cyclophosphamide treatment was compared with placebo treatment for one year in a controlled trial of 14 patients with relapsing/remitting multiple sclerosis. Eight patients received placebo and six patients received cyclophosphamide. The cyclophosphamide group showed a definite trend to have less frequent and less prolonged episodes than(More)
Interleukin (IL) 25 (IL-17E), a distinct member of the IL-17 cytokine family, plays important roles in evoking T helper type 2 (Th2) cell-mediated inflammation that features the infiltrations of eosinophils and Th2 memory cells. However, the cellular sources, target cells, and underlying mechanisms remain elusive in humans. We demonstrate that human Th2(More)
BACKGROUND Alternative splicing is important for increasing the complexity of the human proteome from a limited genome. Previous studies have shown that for some autoantigens, there is differential immunogenicity among alternatively spliced isoforms. OBJECTIVES Herein, we tested the hypothesis that alternative splicing is a common feature for transcripts(More)
BACKGROUND IL-5-producing allergen-specific T cells are thought to play a prominent role in the pathogenesis of allergic inflammation. We hypothesized that T cell allergen-driven IL-5 synthesis is elevated in patients with atopic disease as compared with that in atopic patients free of disease and nonatopic control subjects. OBJECTIVES The purpose of this(More)
Moderate-dose (15 to 20 mg/kg) bolus intravenous (IV) cyclophosphamide is increasingly being employed for the treatment of autoimmune diseases. High-dose (30 to 50 mg/kg) IV cyclophosphamide, which is used in transplantation and oncology, may cause water intolerance and water intoxication. Described herein is the first patient, to our knowledge, to develop(More)
Urticarial vasculitis is a clinico-pathologic entity typified by recurrent episodes of urticaria that have the histopathologic features of leukocytoclastic vasculitis. The cutaneous features may include painful, burning or pruritic skin lesions, the persistence of individual lesions greater than 24 hours, palpable purpura, pronounced central clearing of(More)
The effects of intensive plasma exchange on the serological and clinical manifestations of mildly active systemic lupus erythematosus were evaluated in a controlled, double-blind trial. Twenty patients were randomised to receive either six 4-litre plasma exchanges or a seemingly identical control procedure over a 2-week period. Plasma exchange produced(More)
Interleukin-13 (IL-13) shares many, but not all, of the properties of the prototypic T-helper type 2 (Th2) cytokine IL-4, but its role in allergen-driven T-cell responses remains poorly defined. We hypothesized that allergen stimulation of peripheral blood T cells from patients with atopic disease compared with non-atopic controls results in elevated IL-13(More)
