Modulation of cytokine production by carnitine

Modulation of cytokine production by carnitine

The ability of carnitine congeners to modulate cytokine production by human peripheral blood mononuclear cells (PBMC) was investigated. Modulation of cytokine production by PBMC of young (30 years of age or younger) and old (70 years of age or older) normal donors was first compared. The PBMC were collected over Ficoll-Hypaque and incubated in the presence of various concentrations of acetyl L-...

Modulation of in vitro proliferation and cytokine secretion of human lymphocytes by Mentha longifolia extracts

Objective: Mentha longifolia L. Hudson has been used in folk medicine for various purposes especially for its anti-inflammatory effects. Lymphocytes play a central role in development of inflammation. In the present study, we investigated the immunomodulatory effects of different extracts of M. longifolia on human peripheral blood lymphocytes (PBLs), as main players in development of inflammati...

Differential modulation of cytokine production by macrolides: interleukin-6 production is increased by spiramycin and erythromycin.

Antibiotics do not act alone but act in conjunction with the host defense system. In particular, it has been shown that some antibiotics can modify cytokine production. We compared the in vitro effects of three macrolides (roxithromycin, spiramycin, and erythromycin) actively concentrated by leukocytes on interleukin-1 alpha, (IL-1 alpha), IL-1 beta, IL-6, and tumor necrosis factor alpha produc...

Excessive Inflammation by TFL Production in T Cells for the Regulation of Posttranscriptional Modulation of Cytokine

Effects of C-reactive Protein and Homocysteine on Cytokine Production: Modulation by Pravastatin

OBJECTIVE: C-reactive protein (CRP) and homocysteine are markers of cardiovascular risk that may have inflammatory effects. HMG coenzyme A reductase inhibitors (statins) have anti-inflammatory effects in vitro, but it is not clear if such responses in vivo are secondary to lipid lowering. We examined the hypothesis that CRP and homocysteine would stimulate cytokine release in human whole blood ...
