Lysosomal enzyme release from leucocytes by N-formyl-L-methionyl-L-leucyl-L-phenylalanine in vitro: effect of some anti-inflammatory drugs [proceedings].

Numai utilizatorii înregistrați pot traduce articole

Effects of non-steroidal anti-inflammatory drugs on isolated human polymorphonuclear leukocytes (PMN): chemotaxis, superoxide production, degranulation and N-formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP) receptor binding.

1. We have examined the effects of tolmetin and meclofenamate on isolated human PMN functions under FMLP stimulating conditions. 2. In a dose dependent manner, tolmetin and meclofenamate inhibited all PMN functions, except that tolmetin stimulated PMN chemotaxis. 3. Meclofenamate was much more

New Coumarin Derivatives and Other Constituents from the Stem Bark of Zanthoxylum avicennae: Effects on Neutrophil Pro-Inflammatory Responses.

Numai utilizatorii înregistrați pot traduce articole

Three new coumarin derivatives, 8-formylalloxanthoxyletin (1), avicennone (2), and (Z)-avicennone (3), have been isolated from the stem bark of Zanthoxylum avicennae (Z. avicennae), together with 15 known compounds (4-18). The structures of these new compounds were determined through spectroscopic

The novel multi-cytokine inhibitor TO-207 specifically inhibits pro-inflammatory cytokine secretion in monocytes without affecting the killing ability of CAR T cells.

Cancer immunotherapy using chimeric antigen receptor-armed T (CAR T) cells have been shown to improve outcomes significantly in patients with hematological malignancies. However, cytokine release syndrome (CRS) remains a risk. CRS is characterized by the excessive activation of CAR T cells and

Effects of FMLP and LPS on [Ca2+]i of peritoneal exudate polymorphonuclear leukocytes following onset of inflammation.

Numai utilizatorii înregistrați pot traduce articole

Because a general study of activated neutrophils may have relevance to periodontal diseases and accompanying inflammation, we studied a function of mouse polymorphonuclear leukocytes (PMNs) that exude into the peritoneal cavity in response to inflammation caused by i.p. injection of 2% casein. The

Discovery of Indeno[1,2-c]quinoline Derivatives as Potent Dual Antituberculosis and Anti-Inflammatory Agents.

Numai utilizatorii înregistrați pot traduce articole

A series of indeno[1,2-c]quinoline derivatives were designed, synthesized and evaluated for their anti-tuberculosis (anti-TB) and anti-inflammatory activities. The minimum inhibitory concentration (MIC) of the newly synthesized compound was tested against Mycobacterium tuberculosis H37RV. Among the

N-Tetrahydrofuroyl-(L)-phenylalanine derivatives as potent VLA-4 antagonists.

Numai utilizatorii înregistrați pot traduce articole

Given the proposed involvement of VLA-4 in inflammatory processes, a program to identify orally active VLA-4 antagonists was initiated. Herein, we report the discovery of a N-tetrahydrofuroyl-(L)-phenylalanine derivative (17) and related analogues as potent VLA-4 antagonists with good oral

Activation of oxidative burst and degranulation of porcine neutrophils by a homologous spleen galectin-1 compared to N-formyl-L-methionyl-L-leucyl-L-phenylalanine and phorbol 12-myristate 13-acetate.

Galectins are a family of animal lectins defined by their beta-galactoside-binding activities and a consensus sequence in their carbohydrate-recognizing domain (CRD). Relevant roles of galectins are described in adaptive immune response, innate immunity and modulation of the acute inflammatory

In vivo characterization of 123/125I-2-iodo-L-phenylalanine in an R1M rhabdomyosarcoma athymic mouse model as a potential tumor tracer for SPECT.

Numai utilizatorii înregistrați pot traduce articole

The application of 123I-3-iodo-alpha-methyltyrosine is limited to diagnosis of brain tumors due to its marked long-term uptake in kidneys. In vitro evaluation of 125I-2-iodo-L-phenylalanine showed high uptake in R1M cells by L-type amino acid transport system 1 (LAT1). This study evaluates

Treatment with N-tosyl-l-phenylalanine chloromethyl ketone after the onset of collagen-induced arthritis reduces joint erosion and NF-kappaB activation.

Numai utilizatorii înregistrați pot traduce articole

N-tosyl-l-phenylalanine chloromethyl ketone (TPCK) is known to inhibit NF-kappaB activation and the expression of inflammation mediators in cultured cells. We measured the potential of TPCK to inhibit the pathogenesis of collagen-induced arthritis by blocking NF-kappaB activation. Arthritis was

Neutral endopeptidase activity in the interaction of N-formyl-L-methionyl-L-leucyl-L-phenylalanine with human polymorphonuclear leukocytes.

Human polymorphonuclear leukocytes (PMN) hydrolyze the synthetic chemoattractant N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMet-Leu-Phe) at nanomolar concentrations in an autocatalytic-like manner that deviates from classical Michaelis-Menten kinetics [Yuli, I. & Snyderman, R. (1986) J. Biol.

Activation of neutrophil chemotaxis by leukotriene B4 and 5-hydroxyeicosatetraenoic acid in chronic inflammatory bowel disease.

Circulating neutrophils were investigated in 15 patients with Crohn's disease (CD), 15 with ulcerative colitis (UC), and 15 healthy volunteers. Dose-response curves for chemotaxis in Boyden chambers were analysed for sensitivity to leukotriene B4 (LTB4), its 20-hydroxy-LTB4 (20-OH-LTB4) and

JTE-607, a novel inflammatory cytokine synthesis inhibitor without immunosuppression, protects from endotoxin shock in mice.

OBJECTIVE We investigated the effect of a novel N-benzoyl-L-phenylalanine derivative compound (JTE-607) on production of various cytokines and other immune responses in vitro and on endotoxin shock in vivo. METHODS Human, monkey, rabbit, mouse and rat peripheral blood mononuclear cells (PBMCs), and

(18)F-FBPA as a tumor specific tracer of L-type amino acid transporter 1 (LAT1): PET evaluation in tumor and inflammation compared to (18)F-FDG and (11)C-methionine.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE (18)F-FDG-PET is used worldwide for oncology patients. However, we sometimes encounter false positive cases of (18)F-FDG PET, such as moderate uptake in the inflammatory lesion, because (18)F-FDG accumulates not only in the cancer cells but also in the inflammatory cells (macrophage,
