We studied the influence of abnormal illumination regimen on cell composition of the central and peripheral organs of the immune system in ISIAH rats and control WAG rats. In ISIAH rats, 24-h illumination for 14 days led to more pronounced inhibition of cell proliferation and differentiation in the thymus and more pronounced decrease in splenocyte proliferation and T and B cell counts in the spleen in comparison with WAG rats; however, the level of antigen-presenting cells in the spleen of ISIAH increased. We concluded that ISIAH rats are more sensitive to abnormal illumination regimen than WAG rats. Twenty-four-hour illumination was associated with impairments of central differentiation of T cells and activation of systemic inflammation followed by impairment of differentiation regulation, which can aggravate metabolic dysfunctions in these animals.
