Article Abstract
Fetal growth restriction (FGR) is associated with an increased risk of neonatal morbidity and mortality, as well as the development of metabolic syndrome in adulthood. The present study investigated the regulatory mechanisms of Notch signaling in FGR progression. The expression levels of Notch1 and Jagged1 were determined using reverse transcription-quantitative PCR, western blotting, immunofluorescence staining and immunohistochemistry (IHC). ELISA was used to measure the concentrations of IL-10, IL-17 and IL-35 in serum and placental samples. ELISA and western blotting determined the inflammation- and angiogenesis-related cytokine levels. Th17, Treg and macrophage levels were determined using IHC and flow cytometry. Additionally, hematoxylin & eosin staining and TUNEL assay assessed placenta histology and trophoblast cell apoptosis. Significant trophoblast apoptosis was observed in the placenta of FGR pregnancies. The expression of Notch1 and Jagged1 in peripheral blood mononuclear cells and placental tissues of FGR pregnancies was significantly lower than in the control group. The FGR group exhibited a remarkable inflammation, anti-angiogenesis and immune dysfunction. In conclusion, the Notch signaling pathway mediates immune balance to regulate the development of FGR. These findings offer the potential for advancing innovative predictive, diagnostic and therapeutic approaches for FGR.

Uveitis is an inflammatory eye disease, and Longdan Xiegan Decoction (LXD) has been used to treat uveitis. However, the underlying mechanisms have not fully been addressed. The present study aimed to provide new insights into LXD ameliorating inflammatory response of experimental autoimmune uveitis (EAU) and regulating T helper (Th) cell differentiation via the interaction between microRNA (miRNA) and mRNA.

Diabetes mellitus is a major global health concern associated with micro-and macrovascular complications. Among the diverse mechanisms that contribute to vascular dysfunction in diabetes, endothelial to mesenchymal transition (EndMT) has emerged as a key pathological process. EndMT involves the loss of endothelial cell characteristics and the acquisition of mesenchymal features, resulting in impaired endothelial function, increased fibrosis, and inflammation.

Background: Pathogenic responses against self and foreign antigens in systemic autoimmunity and infection, respectively, engage similar immunologic components, thus lacking distinguishing diagnostic biomarkers. Herein, we tested whether whole-blood transcriptome analysis discriminates autoimmune from infectious diseases.
Methods: We applied nested cross-validation methodology to tune and validate random forests, k-nearest neighbors, and support vector machines, using a new preprocessing method on 22 publicly available datasets, including 594 patients with a broad spectrum of systemic autoimmune diseases and 615 patients with diverse viral, bacterial, and parasitic infections.

Background: Chronic rejection is a major cause of long-term kidney allograft failure, characterized by persistent inflammation and progressive fibrosis. Macrophages are central mediators of this process, but their phenotypic heterogeneity and regulatory mechanisms in chronic rejection remain incompletely understood.
Methods: We performed single-cell transcriptomic analysis on renal allograft biopsies from patients with different types of rejection and on a time-course rat model of chronic rejection.

Asprosin is glucogenic adipokine that exerts a wide repertoire of actions, including the regulation of appetite, insulin resistance and cell proliferation. At present, little is known about the actions of asprosin in the human placenta. The present study investigated the effects of asprosin on the transcriptome of the BeWo and JEG‑3 placental cell lines, and assessed the expression of FBN1/Furin and asprosin's candidate receptors in healthy placentas when compared against placentas from pregnancies where the carrier had gestational diabetes mellitus (GDM).
