Natural killer cells (NK cells) are a population of innate immune lymphocytes capable of cytolysis of infected or transformed cells without prior sensitization. Natural killers are detected in various organs and tissues and may differ in phenotypic and functional characteristics depending on localization. For example, NK cells are the dominant popu...

Communication between natural killer cells (NK cells) and monocytes/macrophages may play an important role in immunomodulation and regulation of inflammatory processes. The aim of this research was to investigate the impact of NK cell-derived large extracellular vesicles on monocyte function because this field is understudied. We studied how NK-cel...

The interaction of natural killer and trophoblast cells underlies maternal-fetal immune tolerance. The data on the participation of endoglin (ENG, CD105), or its soluble form, in the regulation of the communication of these cells are currently insufficient. In this study, we have investigated the role of endoglin in the intercellular interactions b...

Angiogenesis is the development of new blood vessels from pre-existing ones. It is a complex multifaceted process that is essential for the adequate functioning of human organisms. The investigation of angiogenesis is conducted using various methods. One of the most popular and most serviceable of these methods in vitro is the short-term culture of...

During pregnancy, uterine NK cells interact with trophoblast cells. In addition to contact interactions, uterine NK cells are influenced by cytokines, which are secreted by the cells of the decidua microenvironment. Cytokines can affect the phenotypic characteristics of NK cells and change their functional activity. An imbalance of pro- and anti-in...

Natural killer cells (NK cells) are innate immunity lymphocytes. NK cell differentiation is controlled by the cellular microenvironment and locally produced cytokines, including IL-2, IL-15 and IL-18. NK cells are present in various tissues, forming pools of tissue-resident NK cells, e.g., decidual NK cell pool. Peripheral blood NK cells (pNK cells...

Microvesicles (MVs) are plasma extracellular vesicles ranging from 100 (150) to 1000 nm in diameter. These are generally produced by different cells through their vital activity and are a source of various protein and non-protein molecules. It is assumed that MVs can mediate intercellular communication and modulate cell functions. The interaction b...

Natural killer cells (NK) are innate immune lymphocytes produced in the bone marrow. Isolation of NK cells as a separate population of lymphocytes is related to discovery of their ability to induce the death of tumor cells without prior sensitization. In this review, an attempt was made to systematize the numerous data on the biology of NK cells pr...
