Summary: RSA, defined as two or more consecutive pregnancy losses, poses a significant challenge for women of childbearing age, with evidence suggesting an immune background to the condition. Uterine natural killer (uNK) cells, as part of the innate immune system, play a crucial role in pregnancy by accounting for around 70% of total lymphocytes. Understanding the phenotype, origin, receptor, and function of uNK cells can shed light on their relationship with RSA.

Summary: The eutopic secretory phase endometrium in endometriosis overproduces and releases a soluble immunosuppressive CD200 molecule (CD200L) and is populated by stromal cells that contain a truncated CD200 (CD200S) that promotes a proinflammatory environment. The CD200S+ cell population may affect embryo survival in early pregnancy.

Summary: A significant proportion of unexplained reproductive failure is associated with immunological dysfunction at the maternal-fetal interface. Uterine Natural Killer cells (uNK) play a crucial role in successful pregnancy by regulating EVT invasion and spiral artery remodeling. This study explores the frequency, phenotype, and function of uNK subsets in women with unexplained reproductive failure and reveals a global reduction in expression of uNK receptors important for interaction with HLA-C and HLA-G, leading to reduced uNK activation.

Summary: This study investigated the differences in menstrual blood lymphocytes between controls, patients with recurrent pregnancy loss (RPL), and patients with unexplained infertility (uINF). The results showed that RPL patients had significantly higher numbers of CD56+ NK cells in menstrual blood compared to controls, while both RPL and uINF patients had decreased numbers of CD56dimCD16bright NK cells in menstrual blood. These findings suggest altered cytotoxicity in menstrual blood NK cell subtypes of RPL and uINF patients compared to controls.

Summary: RPL and RIF are challenges in reproductive medicine. The immune system plays a pivotal role in endometrial receptivity, successful implantation, and pregnancy complications. Understanding immune dysregulation especially in NK and T cell subtypes may lead to better diagnostic concepts and treatments. Tailored immunotherapy based on endometrial immunophenotyping might be an option for RPL and RIF patients, but further research is needed.

Summary: Recent research has shown that the expression of the uterine gene BMAL1 is reduced in the endometrium of women with recurrent spontaneous abortion. By studying mice, it was found that conditional deletion of the uterine clock gene Bmal1 resulted in mice being able to undergo embryo implantation but unable to sustain pregnancy. Gene ontology analysis revealed suppressed function of uterine NK cells in these mice. Histological examination also showed poor formation of maternal vascular spaces in the placenta. However, progesterone supplementation prolonged pregnancy in some mice and recruited specific NK cells in the spongiotrophoblast layer.

Summary: The CD109 antigen on the endothelial cell surface plays a crucial role in vascular pathology. This study investigated the effect of immobilizing CD109 antigen with specific antibodies on the nanomechanical properties of human umbilical endothelial cells (HUVECs) using atomic force microscopy. The results demonstrated that anti-CD109 antibodies significantly stiffened the cell surface and caused changes in the spatial distribution of mechanical properties. These changes were associated with the activation of the TGF-/Smad2/3 signaling pathway and reorganization of cytoskeletal elements. The findings suggest that CD109 antigen may have a role in regulating the mechanical behavior of endothelial cells.

Summary: Angiogenesis serves as a double-edged sword, defining the boundary between health and disease. While it plays a crucial role in physiological homeostasis, it also supports tumor growth by providing the necessary oxygen and nutrients. Vascular endothelial growth factor (VEGF), a prominent pro-angiogenic factor, is a strategic target in therapeutic methods due to its involvement in tumor blood vessel formation. This article summarizes the molecular mechanisms of VEGF and its diverse role in cancer angiogenesis, as well as the current transformative strategies targeting VEGF to interfere with tumor growth.

Summary: Cancer is a major global health challenge, and researchers are investigating the underlying mechanisms that drive its progression. One area of interest is the role of lysosomal enzymes, specifically cathepsins, in regulating cancer growth and development in the tumor microenvironment (TME). Pericytes, which are important for blood vessel formation in the TME, have been shown to be influenced by cathepsins, although the direct link between pericytes and cathepsins interaction is not yet known. This review aims to explore the potential interplay between pericytes and cathepsins in the TME, highlighting its implications for cancer therapy and future research directions.
