Virus Infection and Lipid Rafts

Biological and Pharmaceutical Bulletin, 2006
Virus entry, assembly, and budding are important processes in the replication cycle of a virus. Viruses are dependent on host living cells for their replication. Viruses use the proliferative mechanism of host cells for replication of viral components.

Low SLC8A1 in Colorectal Cancer Dictates Radiotherapy Resistance Through Calcium‐Dependent ANXA2+sEVs Driving M2 Polarization of TAMs

Advanced Science, EarlyView.
SLC8A1 deficiency in colorectal cancer cells increases intracellular calcium signaling, promoting the secretion of ANXA2‐enriched small extracellular vesicles. These vesicles reprogram tumor‐associated macrophages towards an M2 phenotype, which in turn fosters a tumor microenvironment conducive to radioresistance and is associated with poor patient ...

Who's in, who's out? Re‐evaluation of lipid raft residents

, 2021
Lipid rafts, membrane microdomains enriched with (glyco)sphingolipids, cholesterol, and select proteins, act as cellular signalosomes. Various methods have been used to separate lipid rafts from bulk (non-raft) membranes, but most often non-ionic ...

The Effect of Ligand Reactivity and Carrier Mechanics on Thiol‐Mediated Cellular Uptake for miRNA Nano‐Drugs

Advanced Science, EarlyView.
The effect of ligand reactivity and carrier mechanics on thiol‐mediated uptake was investigated at the single‐molecule/particle level. The interaction kinetics of LA and AspA with membrane thiols were quantified; AspA is more efficient due to the higher binding affinity, greater binding stability, and more double‐disulfide binding, as well as greater ...

Lipid raft-dependent endocytosis: a new route for hepcidin-mediated regulation of ferroportin in macrophages

Haematologica, 2010
Background Expression of the iron exporter ferroportin at the plasma membrane of macrophages is enhanced by iron loading and is decreased by hepcidin. We previously showed that ferroportin is present in specific cell surface domains suggestive of lipid ...

Glycosphingolipid GM3 is localized in both exoplasmic and cytoplasmic leaflets of Plasmodium falciparum malaria parasite plasma membrane

Scientific Reports, 2021
Lipid rafts, sterol-rich and sphingolipid-rich microdomains on the plasma membrane are important in processes like cell signaling, adhesion, and protein and lipid transport.

Of Rafts and Lipid Chain Lengths [PDF]

Biophysical Journal, 2015
Plasma membranes are believed to be highly heterogeneous, and to contain coexisting liquid-ordered domains (known as rafts), which are enriched in cholesterol and sphingomyelin, and liquid-disordered domains. Similar heterogeneities exist in synthetic membrane systems. Previous studies of asymmetric lipid bilayers have demonstrated that the presence of

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

Advanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Neural Stem Cell Spreading on Lipid Based Artificial Cell Surfaces, Characterized by Combined X-ray and Neutron Reflectometry [PDF]

, 2010
We developed a bioadhesive coating based on a synthetic peptide-conjugate (AK-cycloRGDfC]) which contains multiples of the arginyl-glycyl-aspartic acid (RGD) amino acid sequence.

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,
