[Interstrain differences in cellular glucocorticoid reception in mice and the degree of suppression of normal killer activity during immobilization stress].
The correlation between the level of stress-induced natural killer (NK) depression and glucocorticoid binding to specific spleen cell receptors and hormonal profile in inbred mouse strains (CBA, BALB/c, C57BL/c, A/Sn) has been investigated. Stable interstrain differences in stress-induced natural killer activity and glucocorticoid receptor binding (Bm and Kd) have been revealed. It was demonstrated that the mechanism of NK activity depression during stress consists in genetically determined potential sensitivity of lymphoid cells to physiological fluctuations of glucocorticoid levels. This made it possible to identify stress-resistant and stress-sensitive mouse strains.
