Protocol DOI: Caveolins are integral membrane proteins that are the principal structural component of caveolae.

Caveolae are strikingly abundant in endothelial cells, yet the physiological functions of caveolae in endothelium and other tissues remain incompletely understood. Previous studies suggest a mechanoprotective role, but whether this is relevant under the mechanical forces experienced by endothelial cells in vivo is unclear. In this study we have sought to determine whether endothelial caveolae disassemble under increased hemodynamic forces, and whether caveolae help prevent acute rupture of the plasma membrane under these conditions. Experiments in cultured cells established biochemical assays for disassembly of caveolar protein complexes, and assays for acute loss of plasma membrane integrity. In vivo, we demonstrate that caveolae in endothelial cells of the lung and cardiac muscle disassemble in response to acute increases in cardiac output.

Cell Biology: A new regulator of caveolae signalling

The plasma membrane of lymphocytes is highly compartmentalized in so-called nanodomains or protein islands. Proteins such as Caveolin-1 pink , tetraspanins blue or flotillins violet define these protein islands and thereby regulate the functioning of the immune system. In this issue see pages — , Schaffer and Minguet discuss the importance of these protein islands regarding lymphocyte activation and the development of immunopathologies. This cover artwork has been created by Susana Minguet. Anna-Maria Schaffer, Susana Minguet; Caveolin-1, tetraspanin CD81 and flotillins in lymphocyte cell membrane organization, signaling and immunopathology.

Caveolae are submicroscopic, plasma membrane pits that are abundant in many mammalian cell types. The past few years have seen a quantum leap in our understanding of the formation, dynamics and functions of these enigmatic structures.

Plasma membrane invaginations that are coated on their cytoplasmic face by a complex of coat proteins, including clathrin. Best-characterized internalization.

Caveolae protect endothelial cells from membrane rupture during increased cardiac output

In biology , caveolae Latin for "little caves"; singular, caveola , which are a special type of lipid raft , are small 50— nanometer invaginations of the plasma membrane in many vertebrate cell types, especially in endothelial cells, adipocytes and embryonic notochord cells. Yamada in These flask-shaped structures are rich in proteins as well as lipids such as cholesterol and sphingolipids and have several functions in signal transduction. Formation and maintenance of caveolae was initially thought to be primarily due to caveolin , [8] a 21 kD protein. There are three homologous genes of caveolin expressed in mammalian cells: Cav1, Cav2 and Cav3.

Cavin-3 regulates metabolism and cell proliferation by coordinating the activities of growth factor signalling cascades. More than sixty years ago, electron microscopy revealed that the plasma membrane of the cell contains specialized domains with distinct morphologies.

При мысли о том, что Хейл позволил себе прикоснуться к Сьюзан, кровь закипела в его жилах, но он помнил, что должен сохранять ясную голову, Стратмор с горечью признал, что сам отчасти виноват в случившемся: ведь именно он направил Сьюзан в Третий узел. Однако он умел анализировать свои эмоции и не собирался позволить им отразиться на решении проблемы Цифровой крепости. Он заместитель директора Агентства национальной безопасности, а сегодня все, что он делает, важно, как .

Молодые люди поднялись по ступенькам, и двигатель автобуса снова взревел. Беккер вдруг понял, что непроизвольно рванулся вперед, перед его глазами маячил только один образ - черная помада на губах, жуткие тени под глазами и эти волосы… заплетенные в три торчащие в разные стороны косички. Красную, белую и синюю. Автобус тронулся, а Беккер бежал за ним в черном облаке окиси углерода. - Espera! - крикнул он ему вдогонку. Его туфли кордовской кожи стучали по асфальту, но его обычная реакция теннисиста ему изменила: он чувствовал, что теряет равновесие.

Caveolae are bulb-like invaginations made up of two essential structural proteins, caveolin-1 and cavins, which are abundantly present at the plasma membrane of vertebrate cells.
