Peri‐Microvascular Glycogen and Lactate Regulate Capillary Constrictions and Ischemia Outcome in Mice

Journal of Neurochemistry, Volume 170, Issue 4, April 2026.
Disruption of astrocytic glycogen metabolism, induced by glycogen phosphorylase inhibition (DAB) or genetic deficiency of GYS1 (GYS1Nestin‐KO and GYS1Gfap‐KO), reduces lactate availability to pericytes and impairs microvascular function. This metabolic deficit leads to pericyte‐associated capillary constriction, reduced cerebral blood flow, and ...

On‐Demand Chemically Degradable Hydrogels for Biological Applications

ChemBioChem, Volume 27, Issue 6, 27 March 2026.
This review explores the mechanisms and kinetics of chemically induced on‐demand degradation in hydrogels designed for painless dressing removal and traceless dissolution across various biological applications. Covalent bond cleavage and noncovalent disruption triggers are compared, highlighting opportunities for load‐bearing scaffolds with faster ...

Evidence That the Angiotensin IV (AT4) Receptor Is the Enzyme Insulin-regulated Aminopeptidase [PDF]

Journal of Biological Chemistry, 2001
Central infusion of angiotensin IV or its more stable analogues facilitates memory retention and retrieval in normal animals and reverses amnesia induced by scopolamine or by bilateral perforant pathway lesions. These peptides bind with high affinity and specificity to a novel binding site designated the angiotensin AT(4) receptor. Until now, the AT(4)

Sex Difference in Oxytocin-Induced Anti-Hyperalgesia at the Spinal Level in Rats with Intraplantar Carrageenan-Induced Inflammation. [PDF]

PLoS ONE, 2016
Previously, we demonstrated intrathecal administration of oxytocin strongly induced anti-hyperalgesia in male rats. By using an oxytocin-receptor antagonist (atosiban), the descending oxytocinergic pathway was found to regulate inflammatory hyperalgesia ...

Non‐cognate CD8 Binding to MHC I Promotes Positive Selection of an MHC‐E Restricted CD8 T Cell Population

European Journal of Immunology, Volume 56, Issue 3, March 2026.
Mouse Qa1b‐restricted T cells show promiscuous requirements for positive selection. Using in vivo tetramer enrichment, in vitro APC engineering, and in vitro thymocyte stimulation, we demonstrate that a Qa1b‐restricted T cell population can be selected by both Qa1b and H2‐T11, and depends on non‐cognate CD8‐MHC I binding.

Development of a sandwich ELISA to detect circulating, soluble IRAP as a potential disease biomarker

Scientific Reports, 2023
There is growing interest in the use of the enzyme, insulin regulated aminopeptidase (IRAP), as a biomarker for conditions such as cardio-metabolic diseases and ischemic stroke, with upregulation in its tissue expression in these conditions.

Existence of Placental Leucine Aminopeptidase/Oxytocinase/Insulin-Regulated Membrane Aminopeptidase in Human Endometrial Epithelial Cells [PDF]

The Journal of Clinical Endocrinology & Metabolism, 2002
Human endometrial epithelial cells are known to express oxytocin receptors around the time of ovulation. Moreover, oxytocin (OT) and OT-induced prostaglandins appear to play a pivotal role in the switching of endometrial glands from the proliferative to the secretory phase. However, there have been few studies of oxytocinase (OTase), which is identical
