Transglutaminase‐2 Promotes Microglial Synaptic Phagocytosis and Ameliorates Epileptic Seizures by Inhibiting ABCA1 Ubiquitination

CNS Neuroscience &Therapeutics, Volume 31, Issue 12, December 2025.
Our study reveals that Transglutaminase‐2 functions as a key endogenous suppressor of seizure susceptibility. It mediates this effect by promoting microglial phagocytosis of synapses through the inhibition of ABCA1 ubiquitination and subsequent increase in its protein stability.

Formation Mechanism of Two‐Layered AlO(OH) Films on Aluminum Alloys via the Steam Coating Process

Advanced Materials Interfaces, Volume 12, Issue 22, November 22, 2025.
The mechanism of AlO (OH) film formation on Al alloys in a steam atmosphere using a new surface treatment technology, steam coating, is investigated. Liquid phase subcritical water in the autoclave promotes film formation. Furthermore, the two‐layered structure of the film originates from ion diffusion of OH− and Al3+ within the film and crystal ...
