Circular RNA PTPN4 Contributes to Blood‐Brain Barrier Disruption during Early Epileptogenesis

Advanced Science, EarlyView.
Epileptic condition induces CircPTPN4 upregulation, which promotes ECE‐1 expression through competitive sequestration of miR‐145a‐5p. The elevated ECE‐1 catalyzes the ET‐1 production, leading to p38/MAPK pathway activation and subsequent downregulation of tight junction protein expression. This cascade results in increased BBB permeability and enhanced

Substantially Altered Local and Systemic Immunity in Ischemia‐Free Versus Conventional Liver Transplantation

Advanced Science, EarlyView.
This study investigates how ischemia‐free liver transplantation (IFLT) shapes both local and systemic immune responses compared with conventional liver transplantation (CLT). Our findings demonstrate that IFLT confers significant immunological protection by attenuating the STAT3‐HIF‐1α axis and enhancing the Heme‐HMOX1 pathway, two regulatory networks ...

Long‐Term Effects of Xenotransplantation of Human Enteric Glia in an Immunocompetent Rat Model of Acute Brain Injury

Advanced Science, EarlyView.
Acute brain injuries are characterized by extensive tissue damage, resulting in debilitating deficits in patients. Despite considerable progress, cell‐based approaches have yet to identify an ideal candidate. This long‐term study explores the use of an untested cell source – human enteric glia – and a non‐invasive administration route – intranasal ...
