Lipopolysaccharide Stimulates Butyric Acid-Induced Apoptosis in Human Peripheral Blood Mononuclear Cells

Peripheral Blood Mononuclear Cells Acid-Induced Apoptosis in Human Lipopolysaccharide Stimulates Butyric

Lipopolysaccharide stimulates butyric acid-induced apoptosis in human peripheral blood mononuclear cells.

We previously reported that butyric acid, an extracellular metabolite from periodontopathic bacteria, induced apoptosis in murine thymocytes, splenic T cells, and human Jurkat T cells. In this study, we examined the ability of butyric acid to induce apoptosis in peripheral blood mononuclear cells (PBMC) and the effect of bacterial lipopolysaccharide (LPS) on this apoptosis. Butyric acid signifi...

Lactic acid stimulates interleukin-23 production by peripheral blood mononuclear cells exposed to bacterial lipopolysaccharide.

Lactic acid is the predominant acid present in the vagina. We evaluated the consequences of lactic acid, at physiological levels present in the vagina, on cytokine responses of peripheral blood mononuclear cells (PBMCs) obtained from 10 individuals in the presence or absence of bacterial lipopolysaccharide. Preincubation of PBMCs in 15 mM lactic acid before the addition of lipopolysaccharide re...

Optimization of human peripheral blood mononuclear cells (PBMCs) cryopreservation

Cryopreservation is the method of choice for long term storage of human PBMCs. This study was designed to compare the different combinations of variables affecting the cryopreservation of PBMCs samples. The viability of PBMCs separated from 2×5 ml peripheral blood samples obtained from 16 healthy adult volunteers, were measured using trypan blue dye exclusion method just before freezing with ...

transforming growth factor beta-induced is essential for endotoxin tolerance induced by a low dose of lipopolysaccharide in human peripheral blood mononuclear cells

our prior study found  that transforming growth factor  beta-induced (tgfbi) is  an important negative regulator in tlr-induced inflammation. however, whether tgfbi may affect inflammation during lipopolysaccharide (lps)-induced endotoxin tolerance (et) is still unclear.this study aimed to investigate whether tgfbi was involved in the mechanisms of et in human through dampening nuclear factor-k...
