By using video microscopy with fluorescent tagging of the two organelles, the scientists observed that the mitochondria and
lysosomes formed stable contacts inside living human cells.
Not exact matches
Finally, APs fuse with
lysosomes to
form autolysosomes (ALs) that digest and release the breakdown products for re-use, much like a recycling plant would repurpose incoming trash.
When the actin polymerization occurs at one spot on the surface of an autophagosome, which coincides with the location of WHAMM on these organelles, an actin comet tail is
formed, and the rapid assembly / disassembly of the actin polymers «pushes» the autophagosome toward the
lysosome for final processing.
«Cells sequester trash in compartments called autophagosomes» Cells follow a set recipe for recycling: First, the autophagosome is
formed around the trash, next autophagosomes are transported and merged with
lysosomes — another cellular compartment — and finally, the contents are degraded and either secreted or reused by the cell.
The research described in this essay focused on understanding this pathway by identifying protein factors that
form a
lysosome - based signaling platform that positively and negatively regulates the function of the Rags.
Fibril aggregates became condensed in
lysosomes to
form protofilaments and were resistant to intracellular proteolysis.
The striking accumulations of immature AV
forms in dystrophic neurites suggest that the transport of AVs and their maturation to
lysosomes may be impaired, thereby impeding the suspected neuroprotective functions of autophagy.
During macroautophagy, cells
form double membrane - bound vesicles, autophagosomes, that sequester organelles, proteins or portions of the cytoplasm for delivery to the
lysosome [123].

In the lipid storage
form of lysosomal storage disease I mentioned that dogs and cats can be born with decreased or missing
lysosome enzymes that allows them to process fatty substances (lipids).
