Abnormal diurnal variation in circulating natural killer cell phenotypes and cytotoxic activity in major depression.
This investigation tested the hypothesis that depressed patients have abnormal diurnal variation of natural killer (NK) cell measures. The diurnal variation of levels of Leu-11 NK cells and NK cytotoxic activity was significantly less in 24 patients with major depression than in 24 normal comparison subjects. These findings provide evidence that aspects of immune, as well as neural and endocrine, chronobiology are abnormal in depression.
