WebHere, we demonstrate that lipid-protein particle release by autolysosome exocytosis protects neurons from ferroptosis, a form of cell death driven by lipid peroxidation. We show that during oxidative stress, peroxidated lipids and iron are released from neurons by autolysosomal exocytosis which requires the exocytic machinery VAMP7 and syntaxin 4.

WebApr 1, 2024 · Death of neurons can lead to the death of neurons connected to those neurons, a process known as transneuronal degeneration or secondary neuronal loss. This degeneration can occur to neurons either downstream (anterograde) or upstream (retrograde) of dead neurons.
