Lipid rafts and membrane traffic [PDF]
FEBS Letters, 2007 Membrane rafts are regions of increased lipid acyl chain order that differ in their lipid and protein composition from the surrounding membrane. By providing an additional level of compartmentalization they have been proposed to serve many functions in cellular signal transduction and trafficking. We will review their potential involvement in different

Clostridium innocuum, an emerging pathogen that induces lipid raft-mediated cytotoxicity
Virulence, 2023 Clostridium innocuum is an emerging spore-forming anaerobe that is often observed in Clostridioides difficile-associated inflammatory bowel disease (IBD) exacerbations. Unlike C. difficile, C. innocuum neither produces toxins nor possesses toxin-encoding

Lateral phase separation in mixtures of lipids and cholesterol [PDF]
, 2004 In an effort to understand "rafts" in biological membranes, we propose phenomenological models for saturated and unsaturated lipid mixtures, and lipid-cholesterol mixtures.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Breaking the Cycle, Cholesterol Cycling, and Synapse Damage in Response to Amyloid-ß [PDF]
, 2017 Soluble amyloid-β (Aβ) oligomers, a key driver of pathogenesis in Alzheimer disease, bind to cellular prion proteins (PrPC) expressed on synaptosomes resulting in increased cholesterol concentrations, movement of cytoplasmic phospholipase A2 (cPLA2) to ...

Plant Physiology, 2007 Current thinking on lipid membrane organization has evolved from the seminal fluid mosaic model proposed by [Singer and Nicolson (1972)][1]. Subsequent studies on plasma membranes suggest that biological membranes are not a simple homogeneous layer of proteins and lipids, but rather are ...

Lipid rafts and membrane dynamics [PDF]
Journal of Cell Science, 2005 Cell membranes contain a variety of lipid species that differ in their physico-chemical properties. Lipid-lipid immiscibility gives rise to lateral heterogeneities in the membrane plane, a subset of which are termed lipid rafts ([Simons and Vaz, 2004][1]).

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma
Molecular Oncology, EarlyView.Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.
