A simple, nonenzymatic method for desialylating polysialylated ganglio-N-tetraose series gangliosides to produce GM1

Journal of Lipid Research, 1999
Dowex-50W-H+ was used to catalyze the highly selective desialylation of polysialylated ganglio-N-tetraose series gangliosides to yield primarily GM1. High performance thin-layer chromatographic analysis of recovered lipid indicated that 60–70% of the ...

Neuromuscular synaptic function in mice lacking major subsets of gangliosides [PDF]

, 2008
Gangliosides are a family of sialylated glycosphingolipids enriched in the outer leaflet of neuronal membranes, in particular at synapses. Therefore, they have been hypothesized to play a functional role in synaptic transmission.

Dry Deposition Strategies for MALDI–MS Imaging: Principles, Advances and Emerging Applications

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Matrix‐assisted laser desorption/ionisation mass spectrometry imaging (MALDI–MSI) has become a pivotal tool in biomedical research, enabling untargeted, spatially resolved analysis of molecular species in complex biological tissues. Among the critical steps in MALDI–MSI workflows, matrix deposition significantly influences sensitivity, spatial

Chronic Inflammatory Demyelinating Polyneuropathy (CIDP): A Comprehensive Review of Types, Pathophysiology, and Treatment Approaches

Brain and Behavior, Volume 16, Issue 5, May 2026.
Chronic inflammatory demyelinating polyneuropathy is an autoimmune disorder causing demyelination, leading to distal weakness, sensory loss, and autonomic dysfunction. Immune activation triggers macrophage‐mediated myelin damage and conduction failure.

Evidence for the involvement of lipid rafts localized at the ER-mitochondria associated membranes in autophagosome formation [PDF]

, 2016
Mitochondria-associated membranes (MAMs) are subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. This membrane scrambling between ER and mitochondria appears to play a critical role in the earliest steps of autophagy.

Guillain–Barré Syndrome After Malaria: A Case Report of a 7‐Year‐Old Child With Asymmetric Onset of Acute Motor Axonal Neuropathy

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT This case highlights that acute motor axonal neuropathy can present with asymmetric, relapsing weakness in children. In malaria‐endemic and resource‐limited settings, clinicians should consider atypical Guillain–Barré variants early, as timely recognition and treatment can significantly improve outcomes despite diagnostic and systemic ...

SYK Signalling in NLRP3 Inflammasome‐Mediated Response of Murine Microglia Activated by Immune Complexes Formed of Viral Proteins and Specific IgG

European Journal of Immunology, Volume 56, Issue 5, May 2026.
IC‐mediated inflammatory response—the NLRP3 inflammasome activation, cytokine secretion, and antigen presentation depend on SYK signalling pathways in primary murine microglia. ABSTRACT Viral infections might trigger systemic inflammatory responses characterised by inflammasome activation and cytokine release, driven by immune complex (IC) formation ...

Structure of the Myelin Sheath Proteolipid Plasmolipin (PLLP) in a Ganglioside-Containing Lipid Raft

Frontiers in Bioscience-Landmark, 2023
Background: Plasmolipin (PLLP) is a membrane protein located in lipid rafts that participates in the formation of myelin. It is also implicated in many pathologies, such as neurological disorders, type 2 diabetes, and cancer metastasis.

Structural analysis of brain ganglioside acetylation patterns in mice with altered ganglioside biosynthesis [PDF]

, 2013
Gangliosides are sialylated membrane glycosphingolipids especially abundant in mammalian brain tissue. Sialic acid O-acetylation is one of the most common structural modifications of gangliosides which considerably influences their chemical properties ...

Engineered GM1 Intersects Between Mitochondrial and Synaptic Pathways to Ameliorate ALS Pathology

Advanced Science, Volume 13, Issue 20, 9 April 2026.
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease driven by genetic and molecular disruptions affecting energy balance, protein homeostasis, and stress responses in nerve cells. Studies using human and rodent models identified convergent defects in mitochondria and synaptic function.
