The temporary dynamics of inflammation-related genes expression under tuftsin analog Selank action
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this mouse study, the authors examined how the synthetic tuftsin analogue Selank and its fragment Gly-Pro affect the dynamics of C3, Casp1, Il2rg, and Xcr1 gene expression in mouse spleen after a single intraperitoneal injection (100 microg/kg), using real-time PCR. The abstract reports a significant 3-fold decrease in C3 mRNA 30 min after Selank injection and a similar change after Gly-Pro; a wave-like change in Casp1 mRNA; changes in Il2rg mRNA at early time points; and a comparable reduction in Xcr1 mRNA 90 min after either peptide. The authors note frequent coincidence in expression profiles between Selank and Gly-Pro.
Abstract
Previous studies have shown that synthetic tuftsin analogue Selank and its fragments cause a number of alterations in the expression of certain genes involved in inflammation in mouse spleen. In this work we studied the effect of Selank and its short fragment Gly-Pro on the temporary dynamics of C3, Casp1, Il2rg, and Xcr1 genes expression in mouse spleen after single intraperitoneal injection (100 μg/kg) of peptides using real-time PCR method. We found a significant 3-fold decrease in the C3 mRNA level just 30 min after Selank injection and similar alteration this gene mRNA level after Gly-Pro administration. A wave-like alteration in the Casp1 mRNA level was observed after Selank injection. We found a significant alteration in the mRNA level of the Il2rg gene at early time points after Selank and Gly-Pro administration and an almost equal reduction in the Xcr1 mRNA level 90 min after the administration of Selank and its fragment. Our results showed that, Selank and its short fragment Gly-Pro influence the expression of genes that mediate different types of immune responses, thereby maintaining the balance of the immune system. It should be noted that in most cases, there was a coincidence in the expression profiles of the studied genes after Selank and Gly-Pro administration. This might indicate an active contribution of the dipeptide to the final effect of Selank.
