Caveolae (Latin for 'small caves') are flask-shaped membrane invaginations found in most mammalian cells. Caveolin-1, the main coat protein of caveolae, is the dominant protein for the formation of caveolae; mice lacking the Caveolin-1 gene also lack caveolae in every non-muscle cells, providing direct evidence that Caveolin-1 is directly responsible for caveolae assembly. Study of caveolae show that they contain many signalling molecules, and it is now well accepted that caveolae formation is one of the most established approach to segregate and organize signalling complexes in a tri-dimensional manner. The importance of caveolae research is such that one of the pioneer of caveolae research, Dr. Michael Lisanti, is now the 13th most cited scientist of all time.

Caveolae（拉丁语为“小洞穴”）是在大多数哺乳动物细胞中发现的烧瓶状膜内陷。Caveolin-1是Caveolae的主要外壳蛋白，是形成Caveolae的优势蛋白;缺乏Caveolin-1基因的小鼠在每个非肌肉细胞中也缺乏Caveolae，这为Caveolin-1直接负责Caveolae组装提供了直接证据。对小窝的研究表明，它们含有许多信号分子，并且现在公认小窝形成是以三维方式分离和组织信号复合物的最成熟的方法之一。窖穴研究的重要性是这样的，窖穴研究的先驱之一，迈克尔·利桑蒂博士，现在是有史以来第13位被引用最多的科学家。
