How or when are endotoxins released from the bacterial cell?

Endotoxins, which are components of the outer membrane of gram-negative bacteria, are released when the bacterial cell undergoes lysis or breaks apart. Unlike exotoxins, which are secreted by living bacteria, endotoxins are only released after the bacteria are destroyed or when they die. They consist primarily of lipopolysaccharides (LPS), and their release can trigger immune responses in the host, often leading to fever and inflammation.
