Production of lymphocyte-activating factors by mouse macrophages during aging and under the effect of short peptides
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this mouse study, the authors examined production of lymphocyte-activating factor by peritoneal macrophages during aging and its modulation by the short synthetic peptides Vilon, Epithalon, and Cortagen. The abstract reports that lipopolysaccharide-stimulated macrophage production of lymphocyte-activating factors was lower in old animals, and describes what the authors call the first demonstration of opposite modulating effects of the short peptides on production by resident versus lipopolysaccharide-stimulated macrophages in young and old mice. The authors suggest this represents a possible mechanism of immune dysfunction during aging and a potential target for correction with short synthetic peptides. No numerical figures were provided in the abstract.
Abstract
Age-specific characteristics of production of lymphocyte-activating factor by mouse peritoneal macrophages and modulation of this production by short synthetic peptides (Vilon, Epithalon, and Cortagen) were studied. The production of lymphocyte-activating factors by macrophages stimulated with lipopolysaccharides in vitro was lower in old animals. The opposite modulating effects of short peptides on the production of lymphocyte-activating factors by resident and lipopolysaccharide-stimulated macrophages in young and old mice were demonstrated for the first time. This is a possible mechanism of immune system dysfunction during aging, which opens new vistas for its correction with short synthetic peptides.
