Terminal lysosomes
Web1 Jan 2024 · Lysosomes at the pre-synaptic terminal Lysosomes may play a role in both degradative and signalling pathways at the presynaptic terminal. Local pre-synaptic degradative capacity is maintained through the continuous delivery of lysosomes in distal axonal tips ( Farfel-Becker et al., 2024 ). Web9 Dec 2024 · Lysosomes were initially recognized as degradation centers that regulate digestion and recycling of cellular waste. More recent studies document that the lysosome is an important signaling hub that regulates cell metabolism. Our knowledge of the role of lysosomes in immunity is mostly derived from innate immune cells, especially lysosomal …
