Abstract

Chronic insomnia is closely associated with immune dysregulation; however, the immunometabolic characteristics of peripheral T-cell subsets and their relationship with sleep architecture remain largely unclear. This study investigated peripheral T-lymphocyte subsets and their immunometabolic characteristics in patients with chronic insomnia and identified immune indicators associated with sleep parameters. A total of 45 patients with chronic insomnia and 30 healthy controls were enrolled. Flow cytometry quantified T-cell subsets and two mitochondrial parameters: mitochondrial mass, reflecting mitochondrial content, and the percentage of cells with low mitochondrial membrane potential. A total of 37 patients underwent polysomnography. Multiple linear regression identified independent predictors after adjustment for age, sex, and anxiety/depression scores, while receiver operating characteristic analyses evaluated predictive performance. Compared with healthy controls, patients with insomnia showed imbalances in 21 of 30 immune indicators (p < 0.05), including increased frequencies of CD4+ CD45RA− CD62L− PD1+ effector memory T (Tem) cells, accompanied by increased mitochondrial mass and the percentage of cells with low mitochondrial membrane potential in this subset. Multivariate regression identified Tem cell percentage as an independent correlate of N1% (β = 0.184, p = 0.014) and Tem cell count as an independent correlate of sleep efficiency (β = −7.47, p = 0.007). Receiver operating characteristic analysis showed that Tem cell count predicted insomnia with an area under the curve of 0.858 (95% confidence interval: 0.761–0.955), a sensitivity of 95.6%, and a specificity of 66.7% at a cutoff of 18.015. Tem cell count may serve as an immunometabolic biomarker for insomnia assessment.
