1 We tested whether agmatine affects astroglial and macrophage (RAW 264.7 cell line) nitric oxide synthase-2 (NOS-2) expression. Agmatine nitric oxide synthase 2, inducible Mus musculus
2 We tested whether agmatine affects astroglial and macrophage (RAW 264.7 cell line) nitric oxide synthase-2 (NOS-2) expression. Agmatine nitric oxide synthase 2, inducible Mus musculus
3 NOS-2 was induced in these cells by incubation with lipopolysaccharide (LPS) plus three cytokines for astrocytes and LPS alone for RAW 264.7 cells in the presence and absence of varying concentrations of agmatine. Agmatine nitric oxide synthase 2, inducible Mus musculus
4 Agmatine decreased the expression of NOS-2 activity and NOS-2 protein as determined by immunoblot analysis. Agmatine nitric oxide synthase 2, inducible Mus musculus
5 Agmatine decreased the expression of NOS-2 activity and NOS-2 protein as determined by immunoblot analysis. Agmatine nitric oxide synthase 2, inducible Mus musculus
6 These results show that agmatine inhibits the production of nitric oxide by decreasing the activity of NOS-2 in macrophages and astroglial cells by decreasing the levels of NOS-2 protein. Agmatine nitric oxide synthase 2, inducible Mus musculus
7 These results show that agmatine inhibits the production of nitric oxide by decreasing the activity of NOS-2 in macrophages and astroglial cells by decreasing the levels of NOS-2 protein. Agmatine nitric oxide synthase 2, inducible Mus musculus
