Trans-10, cis-12-conjugated linoleic acid attenuates tumor necrosis factor-α production by lipopolysaccharide-stimulated porcine peripheral blood mononuclear cells through induction of interleukin-10.

Conjugated linoleic acid (CLA) can stimulate or inhibit immune cell function, and among CLA isomers, trans-10, cis-12 (t10c12)-CLA was shown to participate in the modulation of pro- or anti-inflammatory cytokine secretion. The objective of this study was to examine the effect of t10c12-CLA on tumor necrosis factor (TNF)-α production by lipopolysaccharide (LPS)-stimulated porcine peripheral blood mononuclear cells (PBMCs). In addition, we determined whether these effects were associated with the induction of interleukin (IL)-10.

Trans-10, cis-12-conjugated linoleic acid modulates NF-κB activation and TNF-α production in porcine peripheral blood mononuclear cells via a PPARγ-dependent pathway.

The activation of PPARγ by ligands, including conjugated linoleic acid (CLA) isomers, plays an important role in the immune response. Among CLA isomers, trans-10, cis-12 (t10c12)-CLA is known to participate in the modulation of pro-inflammatory cytokine secretion. The aim of the present study was to assess the effect of t10c12-CLA on PPARγ activation, NF-κB activation and TNF-α expression in lipopolysaccharide (LPS)-naive and LPS-stimulated porcine peripheral blood mononuclear cells (PBMC).

Attenuation of allergic airway inflammation and hyperresponsiveness in a murine model of asthma by silver nanoparticles.

The use of silver in the past demonstrated the certain antimicrobial activity, though this has been replaced by other treatments. However, nanotechnology has provided a way of producing pure silver nanoparticles, and it shows cytoprotective activities and possible pro-healing properties. But, the mechanism of silver nanoparticles remains unknown.
