Astrocytes and lysosomal storage diseases

Area of Science:

• Biochemistry
• Genetics
• Neuroscience

Background:

• Lysosomal storage diseases (LSDs) are a group of genetic disorders caused by impaired lysosomal function.
• Most LSDs stem from genetic defects in lysosomal enzymes, while others involve mutations in non-enzymatic lysosomal proteins.
• Neuropathological abnormalities are common in LSDs and significantly influence disease progression.

Purpose of the Study:

• To review the potential role of astrocytes in the pathogenesis of LSDs.
• To explore the possibility of targeting glial cells, specifically astrocytes, as a therapeutic strategy for LSD-associated neuropathology.

Main Methods:

• Literature review of studies on lysosomal storage diseases.
• Analysis of research on glial dysfunction, particularly astrocyte involvement, in LSDs.
• Synthesis of findings to evaluate therapeutic potential of targeting astrocytes.

Main Results:

• Astrocytes exhibit dysfunction in numerous LSDs.
• Glial dysfunction, especially in astrocytes, is implicated in neurodegeneration within LSDs.
• Targeting astrocytes may offer a novel therapeutic avenue for LSDs.

Conclusions:

• Astrocytes play a significant role in the neuropathology of LSDs.
• Modulating astrocyte function presents a promising strategy to mitigate neurodegeneration in LSDs.
• Further research into astrocyte-targeted therapies is warranted for LSD treatment.
