Abstract (original English)

Leukopenia remains a major clinical challenge associated with infectious diseases, oncological therapies, autoimmune disorders, and metabolic and iatrogenic conditions. Insufficient leukopoiesis not only increases susceptibility to infections but also limits the intensity and continuity of anticancer and immunosuppressive treatments. Targeted stimulation of leukopoiesis therefore represents a critical therapeutic strategy in modern biomedicine. This narrative review summarizes pharmacological and biotechnological approaches to leukopoiesis stimulation based on an analysis of peer-reviewed literature from major biomedical databases. Emphasis was placed on molecular mechanisms of action, clinical positioning, and translational potential of leukopoiesis-modulating agents. Current leukopoiesis-stimulating strategies encompass cytokine-based therapies, bone marrow-derived peptides, thymic and microbial immunomodulators, nucleic acid-based agents, plant-derived compounds, and chemically synthesized small molecules. Classical colony-stimulating factors remain the cornerstone of clinical practice; however, their limitations, including adverse effects and restricted spectrum of action, have driven the development of alternative approaches. Emerging strategies increasingly target specific regulatory nodes of hematopoiesis, including bone marrow stromal interactions, transcription factor
