Lipidiraidoihin

Lipidiraidoihin, also known as lipid rafts, are small, dynamic, and highly ordered domains within the plasma membrane of animal cells. They are characterized by their enrichment in cholesterol and sphingolipids, which confer a rigid structure to these domains. Lipid rafts are thought to play a crucial role in various cellular processes, including signal transduction, endocytosis, and cell adhesion. They are involved in the sorting and trafficking of membrane proteins and lipids, and they can act as platforms for the assembly of signaling complexes. Lipid rafts are not static structures but are dynamic and can change in size and composition in response to cellular signals. Their role in disease has also been studied, with some evidence suggesting a link between lipid raft dysfunction and conditions such as Alzheimer's disease and cancer. However, the exact mechanisms by which lipid rafts contribute to these diseases are still not fully understood.
