ABSTRACT
Nucleated erythroid cells (NEC) are the precursors of the most massive population of human cells – erythrocytes, for which functions of hemo- and immunoregulation have been shown at various stages of ontogenesis and in various organs and tissues of the human body. NEC perform this function by secreting cytokine proteins, growth factors, enzymes such as arginase-2, ROS, and by surface molecules PD-L1 and PD-L2. Their important regulatory role has been shown for the formation of fetoplacental immunosuppression, immunosuppression during pregnancy, suppression of the response against commensals in the gastrointestinal tract, in the pathogenesis of bacterial and viral infections in adults, in the pathogenesis of tumor growth and autoimmune diseases, as well as participation in the recognition of pathogen-associated molecular patterns using Toll-like receptors in fish and birds. Such qualities, together with their number and width of distribution, represent NEC as active participants in hemo- and immunoregulation, which makes it important to study their regulatory role in health and disease.
