What the tool is doing

Lysosome pH is presented as a dynamic property of the lysosomal lumen that influences degradative and signaling functions. The review frames it as both a sensor and an effector in lysosome biology.

Source 1DOI PubMed

What problem it solves

It provides a mechanistic and translational readout for understanding lysosomal homeostasis and disease-associated dysfunction.

Source 1DOI PubMed

What it does not solve

The abstract does not indicate that lysosome pH alone explains all lysosomal dysfunction or identifies a single causal regulator.

Source 1DOI PubMed

Alternatives

The abstract instead discusses classes of tools used to measure lysosome pH, including fluorescent dyes, genetically encoded biosensors, and nanomaterial-based probes.
