The aim of this study was to determine whether the functional protein tyrosine phosphatase nonreceptor 22 (PTPN22) C1858T polymorphism (rs2476601) confers susceptibility to vasculitis. A meta-analysis was conducted on the PTPN22 C1858T polymorphism across nine comparative studies containing 1,922
Candida albicans water-soluble fraction (CAWS) has microbial pathogen-associated molecular patterns (PAMPs). It is a mannoprotein-β glucan complex obtained from the culture supernatant of Candida albicans NBRC1385 and exhibits vasculitis-inducing activity (CAWS vasculitis) in mice. The sensitivity
BACKGROUND
Vasculitides are classified on the basis of the type of cell involved, namely, eosinophilic vasculitides such as Churg-Strauss syndrome (CSS) and noneosinophilic vasculitides. However, knowledge on inflammatory mediators and oxidative tissue damage associated with vasculitides is
Candida albicans water-soluble fraction (CAWS), a mannoprotein-beta-glucan complex obtained from the culture supernatant of C. albicans NBRC1385, exhibits vasculitis-inducing activity (CAWS-vasculitis) in mice. The sensitivity to CAWS-vasculitis varies greatly among mouse strains. This study
The ability of antineutrophil cytoplasm autoantibodies (ANCA) from patients with systemic vasculitis to stimulate protein kinase C (PKC) and tyrosine kinases was examined in human neutrophils. Using the superoxide dismutase-inhibitable reduction of ferricytochrome C, the kinetics of ANCA-induced
The anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV) are a group of life-threatening multi-system diseases characterized by necrotising inflammation of small blood vessels and crescentic glomerulonephritis. ANCA are thought to play a direct pathogenic role. Previous studies
OBJECTIVE
Positron emission tomography (PET) with the amino acid tracer L-[1-C-11]-tyrosine was evaluated in 27 patients with primary and recurrent brain tumors.
METHODS
Patients underwent either static (n = 14) or dynamic PET (n = 13), with quantification of protein synthesis rate (PSR) and
Anaplastic large cell lymphoma (ALCL) is a T-cell lymphoma histologically characterized by expression of CD30, a cell surface receptor present on activated T cells and B cells. ALCL may occur in a primary cutaneous form or as systemic ALCL with lymph node involvement. Anaplastic lymphoma kinase
Anaplastic lymphoma kinase (ALK)-tyrosine kinase inhibitors (TKIs) dramatically improve progression-free survival compared to cytotoxic agents. It is therefore important to manage patients with ALK-TKIs until drug resistance occurs. Leukocytoclastic vasculitis (LCV) is a rare complication during
Persistent T cell activation is a common finding in anti-neutrophil cytoplasmic autoantibodies (ANCA)-associated systemic vasculitis (AAV) patients. Because imatinib, a selective inhibitor of the ABL, ARG, PDGFR and c-KIT tyrosine kinases, inhibits T cell activation, this study was conducted to
MRL/Mp-lpr/lpr (lpr) mice develop autoantibodies, vasculitis, and glomerulonephritis, which are similar to human systemic lupus erythematosus, and acquire a generalized, nonmalignant, lymphoproliferative disorder. CD4- CD8- CD3+ TCR alphabeta+ (double-negative, DN) T cells accumulate in spleen and
L-3-[123I]-Iodo-alpha-methyl-tyrosine (IMT) is a modified amino acid. It is reported to be avidly taken up in brain tumors, reflecting amino acid transport and is suitable for SPECT.
METHODS
To determine whether tumors outside the brain can also accumulate this tracer, we injected 300-450 MBq IMT
Pretreatment of mice with the hemopoietic growth factor, FMS-like tyrosine kinase 3 ligand (Flt3L), has been shown to increase monocyte-derived myeloid dendritic cells (DC) in lung parenchymal tissue, with possible implications for protective immunity to lung bacterial infections. However, whether
Primary central nervous system vasculitis is confined to the brain and spinal cord. While serological markers of inflammation are usually normal, conventional angiography may confirm the diagnosis. The diagnostic method of choice is central nervous system biopsy. A 57-year-old man suffered from a
