Effect of Neutrophils on Nitric Oxide Production from Stimulated Macrophages
Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whethe...
متن کاملP-95: Effect of Nano Silver on Nitric Oxide Production in Chicken's Sertoli Cells
Background: Chicken sertoli cells are a model to evaluate the effects of toxic Materialss. These cells can actively proliferate in the in vitro conditions and they are able to passage several times. Because of the widespread use of nanosilver in life and also few studies on the effects of these Materialss on different cell lines, evaluation of its toxic effects is felt. Mechanism of nanosilver ...
متن کاملNitric Oxide Functions; an Emphasis on its Diversity in Infectious Diseases
Nitric oxide is a short-lived mediator, which can be induced in a variety of cell types and produces many physiologic and metabolic changes in target cells. It is important in many biological functions and generated from L-arginine by the enzyme nitric oxide synthase. Nitric oxide conveys a variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxici...
متن کاملNitric Oxide Production and Apoptosis Induction in T Cells through Stimulation of Mesenchymal Stem Cells with Zymosan
Background & Aims: Mesenchymal stem cells (MSCs) are non-hematopoietic multipotant cells, which multiply through attaching to culture plates. Toll-like receptors (TLRs) are inherent immune sensors and regulators of immunomodulatory activities of MSCs. The aim of this study was to investigate the effects of zymosan on stem cell polarization into anti-inflammatory phenotypes through the productio...
متن کاملKinetics of Nitric Oxide Production and MTT Reduction by HSV-1 Infected Macrophages
Background: Macrophages have important role in defense against Herpes Simplex Virus type-1 (HSV-1). The present study was performed to determine the viability and nitric oxide (NO) production by HSV-1 infected mouse peritoneal macrophages (HIM). Method: The viability of macrophages was evaluated using MTT reduction assay and the production of nitrite using Griess method. Results: The ability of...
متن کاملDetermination of Optimum Conditions for the Production of Peptides with Antioxidant and Nitric-Oxide Inhibition Properties from Protein Hydrolysis of Pumpkin Seed Meals Using Pepsin Enzyme
Background and Objectives: In this study, hydrolysis condition optimization of the pumpkin (Cucurbita pepo) seed proteins was carried out achieve maximum DPPH radical scavenging and nitric-oxide inhibition properties using Design Expert Software and response surface methodology. Materials & Methods: In general, 1–3% concentrations of pepsin enzyme, 30–40 °C temperature and 120–100 min time we...
