= Lipid bilayer fusion
{wiki=Lipid_bilayer_fusion}
Lipid bilayer fusion is a biological process in which two lipid bilayers merge to form a single, continuous bilayer. This phenomenon is crucial for many cellular processes, including membrane transport, signal transduction, and the fusion of vesicles with target membranes—such as during neurotransmitter release at synapses, hormone secretion, and viral entry into host cells. The process involves several steps: 1. **Approach**: Two lipid bilayers come into proximity.
