Main Results:

Tubules are extruded from autolysosomes during ALR.
Proto-lysosomes bud from these tubules, containing lysosomal membrane components.
Proto-lysosomes mature into functional lysosomes, restoring lysosome pool.

Conclusions:

ALR is a complex, tightly regulated process essential for cellular function.
Understanding ALR mechanisms offers insights into lysosome-related diseases.
Further research into ALR regulation and function is warranted.
