In T cells, the coupling of the outer and inner lipid microdomains is mediated by cholesterol. By contrast, the crosslinking of TCR/CD3 triggers the formation ...

Lipid rafts in T cell receptor signalling (Review) - PMC

Biochemical studies using purified detergent-resistant membranes (DRM) and confocal microscopy have suggested that upon stimulation, the TCR and Lck-containing ...

Lipid rafts and their roles in T-cell activation - ScienceDirect.com

Abstract. Lipid rafts are defined as detergent-resistant membrane microdomains of specific lipid and protein composition. They are involved in many aspects of ...

Membrane Rafts in T Cell Activation: A Spotlight on CD28 ...

Spatiotemporal compartmentalization of signaling pathways and second messengers is pivotal for cell biology and membrane rafts are, therefore, required for ...

The T cell receptor resides in ordered plasma membrane ... - Nature

All these pathways can be activated by crosslinking different lipid raft components, the ganglioside GM1 or the GPI-anchored protein CD59, ...

Mutual regulation between membrane rafts and protein condensates ...

Specifically, the transmembrane protein Linker for Activation of T cells (LAT) is phosphorylated upon antigenic stimulation to multivalently interact with ...

CD4 and CD8 T cells require different membrane gangliosides for ...

Gangliosides are major components of lipid rafts. While investigating T-cell activation in ganglioside-deficient mice, we observed that CD4+ and CD8+ T cells ...

Synthetic lipid rafts formed by cholesterol nano-patch induce T cell ...

Lipid rafts are small and dynamic membrane compartments that are enriched with cholesterols or sphingolipids. The coalescence of small lipid ...

The role of lipid rafts in T cell antigen receptor (TCR) signalling

Together the data suggest that lipid rafts are important in controlling appropriate protein interactions in resting and activated T cells, and that aggregation ...

Organization of plasma membrane functional rafts upon T cell ...

In resting T cells from peripheral blood Lck and the raft glyco- sphingolipid GM1 resided in intracellular membranes. T cell activation induced synthesis of.

Specifically, the transmembrane protein Linker for Activation of T cells (LAT) is phosphorylated upon antigenic stimulation to multivalently ...

Transcriptional Regulation of T-Cell Lipid Metabolism - Frontiers

It is well established that cholesterol and glycosphingolipids are enriched in the plasma membrane (PM) and form signaling platforms called lipid rafts, ...

Structure and function of lipid rafts in human activated T cells

Abstract. Lipid rafts, specialized membrane microdomains enriched in sphingolipids and cholesterol, have been shown to function as signaling ...

The Functional Roles of Lipid Rafts in T Cell Activation, Immune ...

The first appearance of lipid rafts, or lipid rafts-like structure, was occasionally observed by cryo-electronic microscopy in 1980s as ...

A sensitive S-Trap-based approach to the analysis of T cell lipid raft ...

The analysis of T cell lipid raft proteome is challenging due to the highly dynamic nature of rafts and the hydrophobic character of ...

Human CD8+ T cells do not require the polarization of lipid rafts for ...

It is thought that, on activation of T cells, lipid microdomains in the cell membrane form larger lipid rafts (24). Apart from this change in size, lipid rafts ...

The role of lipid rafts in signalling and membrane trafficking in T ...

T cell activation induces a rapid compartmentalisation of signalling machinery into reorganised rafts that are used as platforms for the ...
