Clostridium difficile-derived membrane vesicles promote fetal growth restriction via inhibiting trophoblast motility through PPARγ/RXRα/ANGPTL4 axis.

Fetal growth restriction (FGR) is a common complication of pregnancy, which seriously endangers fetal health and still lacks effective therapeutic targets. Clostridium difficile (C. difficile) is associated with fetal birth weight, and its membrane vesicles (MVs) are pathogenic vectors.

Influence of gut flora on diabetes management after kidney transplantation.

Post-transplant diabetes mellitus (PTDM) is a common complication following renal transplantation, and its incidence has been gradually increasing in recent years, posing a significant public health challenge. Managing PTDM is complex, as studies suggest that it involves changes in the microbial flora across multiple organs. Recent research highlights the critical role of gut flora metabolism in the development of diabetes among post-renal transplant patients.

Human neural stem cells directly programmed from peripheral blood show functional integration into the adult mouse brain.

Transplantation of induced pluripotent stem cell-derived neural cells represents a promising strategy for treating neurodegenerative diseases. However, reprogramming of somatic cells and their subsequent neural differentiation is complex and time-consuming, thereby impeding autologous applications. Recently, direct transcription factor-based conversion of blood cells into induced neural stem cells (iNSCs) has emerged as a potential alternative.

Non-invasive determination of gene expression in placental tissue using maternal plasma cell-free DNA fragmentation characters.

Background: The expression profiles of placental genes are crucial for understanding the pathogenesis of fetal development and placental-origin pregnancy syndromes. However, owing to ethical limitations and the risks of puncture sampling, it is difficult to obtain placental tissue samples repeatedly, continuously, multiple times, or in real time. Establishing a non-invasive method for predicting placental gene expression profiles through maternal plasma cell-free DNA (cfDNA) sequencing, which carries information about the source tissue and gene expression, can potentially solve this problem.
