Sphingomyelin is a type of sphingolipid that is an essential component of cell membranes, particularly nerve cells. It plays a key role in maintaining the structure and function of cell membranes, as well as in cell signaling processes. Research in the area of sphingomyelin focuses on understanding its role in various cellular processes, its involvement in diseases such as cancer and neurodegenerative disorders, and potential therapeutic strategies targeting sphingomyelin metabolism. Studies have shown that alterations in sphingomyelin levels can impact cell survival, proliferation, and inflammatory responses, making it an important area of investigation in the field of lipid biology and molecular biology.
