Substance P and other polycationic peptides are thought to stimulate mast cell degranulation via direct activation of G proteins. We investigated the ability of extracellularly applied substance P to translocate into mast cells and the ability of intracellularly applied substance P to stimulate degranulation. In addition, we studied by reverse transcription--PCR whether substance P-specific rec...
The interaction of substance P with human blood T-lymphocytes, which stimulates T-lymphocyte proliferation, was quantified by both flow cytometric and direct binding assays. Fluorescence-detection flow cytometry recorded the binding of dichlorotriazinylamino-fluorescein-labeled substance P to 21 +/- 10% (mean +/- SD, n = 6) and 35 +/- 8% (n = 2) of human blood T-lymphocytes before and after sti...
background and aim: one of the common problems in people with obsessive-compulsive disorder and substance abuse is emotion regulation difficult. the aim of this study was to compare emotion regulation strategies in people with obsessive-compulsive disorder, substance abuse and normal people. materials and methods: this study was conducted with historical cohort method. 40 patients with ocd, 40 ...
Internalization of the NK1 receptor (NK1R) and substance P was observed in cells transfected with cDNA encoding the rat NK1R by using anti-receptor antibodies and cyanine 3-labelled substance P (cy3-substance P). After incubation at 4 degrees C, NK1R immunoreactivity and cy3-substance P were confined to the plasma membrane. Within 3 min of incubation at 37 degrees C, NK1R immunoreactivity and c...
Substance P, a member of the tachykinin family, is expressed in primary invasive malignant melanomas, metastatic melanomas, melanomas in situ, atypical naevi, and spindle and epithelioid cell naevi. The role of substance P in cancer development and progression is not clear. Radiotherapy, which is used extensively in the treatment of malignancies, alters substance P levels. It is, however, not k...
PURPOSE OF REVIEW More than half of the world's population is living in urban areas, but the evidence about urban-rural differences in drug use is not clearly defined. The present paper aims to review the international literature addressing the role of urbanization and related parameters in association with substance misuse. In particular, the evidence of urbanization being a risk factor for su...
To study the roles of substance P and endogenous neutral endopeptidase in mediating cough, we measured cough responses in awake guinea pigs in response to exogenous substance P and capsaicin aerosols in the presence and absence of the neutral endopeptidase inhibitors leucine-thiorphan and phosphoramidon. Substance P stimulated cough in very low concentrations (10(-17)-10(-16) M). In a second st...
