一般說明

胆固醇半琥珀酸酯(CHEMS)是一种酸性胆固醇酯。它在碱性和中性水性介质中自组装成双分子层。CHEMS表现出pH敏感性聚合。它由琥珀酸与胆固醇的β-羟基发生酯化反应而形成。这种化学修饰使CHEMS能够在合适的水性介质中进行薄层组装,而胆固醇在水性环境中形成一水合物晶体。

A major hurdle towards in vivo utilization of pH-sensitive liposomes is their prompt sequestration by reticuloendothelial system and hence short circulation time. Prolonged circulation of liposomes is usually achieved by incorporation of pegylated lipids, which have been frequently reported to

Transient receptor potential melastatin 2 (TRPM2) is a Ca2+-permeable cation channel required for immune cell activation, insulin secretion, and body heat control. TRPM2 is activated by cytosolic Ca2+, phosphatidyl-inositol-4,5-bisphosphate and ADP ribose. Here, we present the ~3 Å resolution electron
