eIF2B activator prevents neurological defects caused by a chronic integrated stress response

eLife, 2019
The integrated stress response (ISR) attenuates the rate of protein synthesis while inducing expression of stress proteins in cells. Various insults activate kinases that phosphorylate the GTPase eIF2 leading to inhibition of its exchange factor eIF2B ...

AI‐Designed TREM1‐Targeted LYTAC Nanoparticles Reprogram the Neuroimmune Microenvironment in Traumatic Brain Injury

Advanced Science, EarlyView.
AI‐enabled de novo design of a TREM1 binder, integrated into a BBB‐crossing and macrophage‐targeted nanoplatform, enables TREM1 degradation and attenuates neuroinflammation, thereby promoting neuroprotection and tissue repair after traumatic brain injury. ABSTRACT Secondary neuroinflammation drives progressive damage after traumatic brain injury (TBI),

A Nanoscale Model System for the Human Myelin Sheath [PDF]

, 2021
Here, we for the first time establish nanodiscs with the challenging lipid composition of myelin of the peripheral or central nervous systems, respectively (PNS and CNS, both containing >40% cholesterol, which so far has been thought to be detrimental ...

Proteomics of bovine myelin sheath: Characterization of a truncated form of P0 by MALDI-TOF/TOF mass spectrometry [PDF]

Journal of the American Society for Mass Spectrometry, 2006
The glycoprotein P0, the major structural protein of the peripheral nerve myelin, plays a critical role in holding myelin lamellae together via interaction of both extracellular and cytoplasmic domains. Mutations in the human P0 gene give rise to severe and progressive forms of dominantly inherited peripheral neuropathies like CMT1B.

Lysosomal multi-omics reveals altered sphingolipid catabolism associated with lysosomal dysfunction in the aging brain

Cell Reports
Summary: Lipids dynamically reside in multiple intracellular locations, and their organellar distribution is important for function. During brain aging, lysosomal lipid changes have been noted, but lipid identity, interactions, and functional relevance ...

Time-lapse imaging of the dynamics of CNS glial-axonal interactions in vitro and ex vivo [PDF]

, 2012
<b>Background</b> Myelination is an exquisite and dynamic example of heterologous cell-cell interaction, which consists of the concentric wrapping of multiple layers of oligodendrocyte membrane around neuronal axons.

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

Advanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Changes in the Oligodendrocyte Progenitor Cell Proteome with Ageing. [PDF]

, 2020
Following central nervous system (CNS) demyelination, adult oligodendrocyte progenitor cells (OPCs) can differentiate into new myelin-forming oligodendrocytes in a regenerative process called remyelination.

Brain Citrullination Patterns and T Cell Reactivity of Cerebrospinal Fluid-Derived CD4+ T Cells in Multiple Sclerosis

Frontiers in Immunology, 2019
Immune responses to citrullinated peptides have been described in autoimmune diseases like rheumatoid arthritis (RA) and multiple sclerosis (MS). We investigated the post-translational modification (PTM), arginine to citrulline, in brain tissue of MS ...

A Novel Bioactive Component, Efoba, From Aged Garlic Targets CTSC to Suppress NET‐Driven Neuroinflammation and Ameliorate Secondary Brain Injury After Intracerebral Hemorrhage

Advanced Science, EarlyView.
Efoba, a novel bioactive component derived from aged garlic, confers neuroprotection against intracerebral hemorrhage. It acts on microglia to suppress CTSC release, inhibits NET‐mediated neural injury, and blocks pathological microglia‐neutrophil crosstalk. This study provides a highly promising lead compound for hemorrhagic‐stroke therapy.
