Expansion Microscopy Reveals the Spatial Association of Therapeutic Antibody–Receptor Complexes With Cholesterol‐Rich Membrane Domains

Angewandte Chemie, EarlyView.
We report a super‐resolution strategy that maps cholesterol‐rich membrane domains in whole, intact cells with an effective spatial resolution of ∼40 nm by combining expansion microscopy with a perfringolysin O domain 4 probe. This approach enables direct visualization of the spatial association between CD20 and CD38 complexes and cholesterol‐rich ...

Phase composition of lipoprotein SM/cholesterol/PtdCho affects FA specificity of sPLA2s

Journal of Lipid Research, 2008
We have previously reported preferential release of polyunsaturated FAs during hydrolysis of lipoprotein phosphatidylcholine (PtdCho) by group X secretory phospholipase A2 (sPLA2) and preferential release of oligounsaturated FAs during hydrolysis of ...

Neuromorphic Devices and Computing for Sensing, Memory, and Control

Advanced Science, EarlyView.
This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Pharmacological reversion of sphingomyelin‐induced dendritic spine anomalies in a Niemann Pick disease type A mouse model

EMBO Molecular Medicine, 2014
Understanding the role of lipids in synapses and the aberrant molecular mechanisms causing the cognitive deficits that characterize most lipidosis is necessary to develop therapies for these diseases.

Exchange of phospholipid classes between liver microsomes and plasma: comparison of rat, rabbit, and guinea pig

Journal of Lipid Research, 1971
Rat and guinea pig liver microsomes labeled with phospholipid 32P were incubated with rat, guinea pig, and rabbit plasma in a KC1–Tris–EDTA buffer. A net transfer of microsomal phosphatidylcholine and phosphatidylethanolamine to plasma was observed.

Visualizing sphingomyelin in the retina

Experimental Eye Research
Sphingomyelin (SM) is a major component of cellular membranes that is altered by retinal and optic nerve degenerations. However, our understanding of the influence of SM during degenerations is hampered by methodological limitations. Prior investigations have demonstrated the accumulation of SM to plasma membranes of cultured cells, using an enhanced ...

Gut Microbiota‐Isoallolithocholic Acid Crosstalk Promotes Calcium Oxalate Kidney Stone Formation via PARP1‐Mediated Parthanatos

Advanced Science, EarlyView.
ABSTRACT Bile acids have been implicated in calcium oxalate (CaOx) nephrolithiasis. Here, we employ multi‐omics approaches to identify isoallolithocholic acid (isoalloLCA) as the key bile acid elevated in the feces, serum, kidney, and urine of CaOx rats, confirmed by spatial metabolomics.

ACSL4‐Dependent Lysosomal Lipid Peroxidation Links WTAP‐Mediated m6A Modification to Intervertebral Disc Degeneration

Advanced Science, EarlyView.
IL‐1β upregulates the protein level of WTAP, which promotes the m6A modification of ACSL4 mRNA in an IGF2BP2‐dependent manner, thereby enhancing its stability. The increased ACSL4 drives lipid peroxidation, leading to lysosomal membrane permeabilization (LMP) and impaired mitophagy, which collectively accelerate intervertebral disc degeneration (IVDD).

Sphingomyelin synthase SMS2 displays dual activity as ceramide phosphoethalomine synthase. [PDF]

, 2009
Sphingolipids are vital components of eukaryotic membranes involved in the regulation of cell growth, death, intracellular trafficking, and the barrier function of the plasma membrane.

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.
