We propose that redistribution of specific membrane microdomains, termed rafts, during cell migration is a pivotal step in achieving polarity. On the one hand, partitioning of molecules into rafts might help to localize proteins at ...

Phospholipids are prevalent in the cells of bacteria and eukaryotes. They are molecules made of a phosphate head and a lipid tail. The head is considered water-loving or hydrophilic, whereas the tail is hydrophobic, or repellent to water. Phospholipids are therefore called amphiphilic. Because of ...

It is mediated by caveolins, integral membrane proteins that preferentially oligomerise in cholesterol-rich lipid rafts to form the membrane invagination. Through the caveolin-dependent endocytosis, the uptake of extracellular material can also be mediated by specific receptors [32,33]. Caveolin-...
Cell membrane lipid rafts mediate caveolar endocytosis of HIV-1 Tat fusion proteins. J. Biol. Chem. 2003, 278, 34141–34149. [CrossRef] [PubMed] 89. Richard, J.P.; Melikov, K.; Brooks, H.; Prevot, P.; Lebleu, B.; Chernomordik, L.V. Cellular uptake of unconjugated TAT ...
Pre-treatment of IECs with methyl-β-cyclodextrin (MβCD) partially blocked the OMV-induced host responses, indicating a role for lipid rafts in the host cell plasma membrane during interactions with C. jejuni OMVs [Citation98]. A recent study has investigated the mechanisms of host cell-...
the presence of Tat-specific antibodies or CTL frequencies are associated with slow or non-progression to AIDS, we will also discuss the role of Tat as a potential vaccine candidate, the advances made in this field, and the importance of using a Tat protein capable of eliciting a protective ...
Consequently, these results indicate that Piezo1 function is strongly dependent on the membrane mechanical properties and lateral organization of membrane cholesterol domains, referred to also as “lipid rafts” (Nicolson 2014), which coordinate the concerted channel activity. Lipid rafts are membrane ...
5.Lipid Rafts vs Caveolae in Tabular Form 6.Summary – Lipid Rafts vs Caveolae What are Lipid Rafts? Lipid raft is a microdomain of the plasma membrane. It has a flat structure. The plasma membranes of the cells contain combinations of glycosphingolipids, cholesterol and protein receptors, ...
