The effects of the interleukins IL-7 and IL-9 on cell cycle progression were investigated by conventional [3H]thymidine incorporation and by the bivariate BrdU/Hoechst technique. Both IL-7 and IL-9 drive phytohemagglutinin-activated T cells through more than one cell cycle, but IL-7 was more potent on cell cycle progression than IL-9. Neither synergistic nor inhibitory effects were seen between...

Background: The critical role of interleukin-7 (IL-7) in homeostatic proliferation and T cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. Methods: In the present study we expressed recombinant human interleukin-7 (rhIL-7) in Chinese hamster ovary (CHO)-K1 cells. CHO-K1 cells were stably transfected ...

AIM: to study the cytokine link of immunity in patients with new coronavirus infection COVID-19 and possibility using these data predict risk lung tissue damage.
 MATERIALS AND METHODS: Patients diagnosed were divided into 4 groups depending on severity disease: 1 asymptomatic patients; 2 damage amount 25%; 3 50%; 75% (according results computed tomography). Immunological studies performed...
