In the present study, methanol extract of Ocimum gratissimum Linn (ME-Og) was tested against nicotine-induced murine peritoneal macrophage in vitro. Phytochemical analysis of ME-Og shown high amount of flavonoid and phenolic compound present in it. The cytotoxic effect of ME-Og was studied in murine peritoneal macrophages at different concentrations (0.1 to 100 microg/ml) using the 3-(4, 5-dime...
Cholesteryl ester (CE) accumulation in arterial wall macrophages (foam cells), mediated by the intracellular enzyme acyl coenzyme A:cholesterol acyl transferase (ACAT), is a prominent feature of atherosclerotic lesions. However, native low density lipoprotein (LDL) does not cause activation of ACAT or CE accumulation in cultured mouse peritoneal macrophages despite both substantial LDL uptake a...
BACKGROUND High baseline peritoneal solute transport rate is reportedly associated with reduced patient and technique survival in continuous peritoneal dialysis (PD) patients. However, the determinants of baseline peritoneal solute transport rate remain uncertain. The aim of this study was to investigate the relationship between peritoneal local inflammation, angiogenesis and systemic inflammat...
The CD98 heavy chain (CD98hc) regulates virus-induced cell fusion and monocyte fusion, and is involved in amino acid transportation. Here, we examined the role that CD98hc plays in the formation of osteoclasts using CD98hcflox/floxLysM-cre peritoneal macrophages (CD98hc-defect macrophages). Peritoneal macrophages were stimulated with co-cultured with osteoblasts in the presence of 1,25(OH)2 vit...
The peritoneal cavity of guinea pigs proved to be a rich source of mononuclear cells (34-52%) with fibrinogen or fibrin (Fib) on their surface. The Fib was readily detected on the surface of viable cells in suspension by fluorescence microscopy using antisera to guinea pig fibrinogen. The fluorescent staining occurred either in a speckled distribution, similar to that of cytophilic IgG, or in a...
Excessive consumption of ethanol (EtOH) suppresses innate immunity, but the mechanisms have not been fully delineated. The present study was conducted to determine whether EtOH suppresses TLR signaling in vivo in mice and to characterize the downstream effects of such suppression. Degradation of IL-1R-associated kinase 1 induced by a TLR3 ligand in peritoneal cells ( approximately 90% macrophag...
CPT-11 is a first-line chemotherapeutic agent for the treatment of colorectal cancer in clinic. Previous studies including ours have demonstrated that CPT-11 is, however, toxic to the intestinal epithelium and resident peritoneal macrophages. By interacting with B1 cells, the resident peritoneal macrophages play critical roles in the maintenance of gastrointestinal homeostasis. It remains there...
Using the in vitro polyclonal blastogenesis test, we identified peritoneal suppressor cells from L1210 leukemia-bearing mice as Ia-negative macrophages. These cells manifested adherence to plastic tubes and sensitivity to silica but not to X-irradiation and treatment with alpha Thy 1.2 or alpha Ia 7 antibody plus complement. The suppressor activity of peritoneal macrophages was detected as earl...
During infection and inflammation, circulating monocytes leave the bloodstream and migrate into tissues, where they differentiate into macrophages. Macrophages express surface Toll-like receptors (TLRs), which recognize molecular patterns conserved through evolution in a wide range of microorganisms. TLRs play a central role in macrophage activation which is usually associated with gene express...
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...
