Role of Neurohumoral Imbalance at Post-Traumatic Stress Disorder in the Antitumor Immune Response. Experimental Study

Dokl Biol Sci. 2023 Aug;511(1):241-246. doi: 10.1134/S0012496623700394. Epub 2023 Oct 13.

Abstract

The aim of the study is to investigate the growth and development of B16 melanoma in mature male C57Black/6 mice with a post-traumatic stress disorder (PTSD) model. Behavioral, immunohistochemical, morphometric methods, enzyme immunoassay were used. A forced decrease in the level of corticosterone, which is characteristic for PTSD, was established, followed by intensification of the production of increased concentrations of pro-inflammatory interleukins by the cells of the immune system and, at the same time, a decrease in the secretion of anti-inflammatory cytokines. Priority data were obtained: the neurohumoral imbalance that develops in PTSD is a limiting factor to the growth of B16 melanoma, at least at the initial stages of the oncological process.

Keywords: corticosterone; interleukins; mice; post-traumatic stress disorder; В16 melanoma.
