Results show that the addition of cholesterol significantly increased both the amount of insoluble lipid rafts-like structures and their stability, and that the availability of a minimum amount of sphingolipid was necessary to produce larger amounts of more stable structures. However, the addition of...

Saturated FAs in the raft sphingolipids and phospholipids are closely packed with cholesterol resulting in more ordered and less fluid membranes than the rest of the PM. Many signaling proteins are concentrated in lipid rafts via direct lipidation (e.g., palmitoylation) or lipid-binding domains, ...
Cholesterol (Chol) fortifies packing and reduces fluidity and permeability of the lipid bilayer in vesicles (liposomes)-mediated drug delivery. However, under the physiological environment, Chol is rapidly extracted from the lipid bilayer by biomembranes, which jeopardizes membrane stability and results ...
Moreover, in TME-rich tumors, recruitment of non-malignant host cells, such as immunosuppressive cells, CAFs, cancer-associated adipocytes (CAAs), can be induced by tumor- or stromal-derived lipid mediators (e.g., Prostaglandin E2 (PGE2), fatty acids (FAs), cholesterol) and the acquisition ...
Rafts are highly dynamic and their proteolipid composition is influenced by the external concentration of lipids, especially cholesterol. Lipid rafts appear to be critically involved in several steps of viral infections. Enveloped viruses, such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV...
Lipid rafts (dark green head groups) are enriched in cholesterol and contain a PI glycan-linked (GPI) protein. The purple head groups depict lipids in close association with protein. The irregular surface and wavy acyl chains denote the fluid nature of the bilayer. Table 1. Lipid Composition ...
