Abstract
It was found that 28-day immobilization stress in male Wistar rats leads to significant increase in the serum concentrations of proinflammatory cytokines IL-1β, IL-6, IFNγ, and monocyte chemoattractant protein-1 (MCP-1) and a decrease in the content of anti-inflammatory IL-10, as well as the ratio IL-1β/IL-10, IL-6/IL-10, and IFNγ/IL-10 compared to non-stressed animals. Administration of the heptapeptide tuftsin-Pro-Gly-Pro produced a corrective effect on cytokine concentrations under stress conditions: at a dose of 750 μg/kg, the peptide decreased the concentrations of IL-1β, IFNγ, and MCP-1 and cytokine ratios (IL-1β/IL-10 and IFNγ/IL-10), while at a dose of 250 μg/kg, it increased IL-10 levels and decreased IL-6/IL-10 and IFNγ/IL-10 ratios.
期刊介绍：
Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005.
World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells.
The Russian Volume Year is published in English from April.
