Lipid rafts

Lipid rafts are small, specialized areas within the cell membrane composed of tightly packed lipids and proteins. They act as organizing centers, helping the cell coordinate signaling, communication, and trafficking functions more efficiently. These rafts are more ordered and less fluid than surrounding membrane regions, allowing specific molecules to gather and work together. Lipid rafts play important roles in processes like immune response, nerve signaling, and pathogen entry, making them crucial for proper cell functioning and communication.
