The physiological functions of human peroxisomes

Area of Science:

• Cell Biology
• Human Physiology
• Metabolic Disorders

Background:

• Peroxisomes are essential subcellular organelles involved in diverse metabolic functions.
• Their proper functioning relies on interactions with other organelles like lipid droplets, lysosomes, ER, and mitochondria.
• Impaired peroxisomal function leads to severe genetic disorders such as Zellweger spectrum disorders and X-linked adrenoleukodystrophy.

Purpose of the Study:

• To review the metabolic roles of human peroxisomes.
• To emphasize the metabolic partnerships between peroxisomes and other organelles.
• To discuss the consequences of genetic defects in peroxisomal biogenesis and function.

Main Methods:

• Literature review of current knowledge on peroxisomal metabolism.
• Analysis of the role of tethering proteins in organelle interactions.
• Inclusion of data from model systems, including peroxisomal mouse models.

Main Results:

• Peroxisome interactions with other organelles are mediated by tethering proteins for efficient metabolite transfer.
• Genetic defects in peroxisomal biogenesis and function result in severe human diseases.
• Peroxisomes play a significant, though often underestimated, role in viral infections.

Conclusions:

• Understanding peroxisome-organelle partnerships is crucial for comprehending human health and disease.
• Further research into peroxisomal roles, including in viral infections, is warranted.
• Model systems provide valuable insights into peroxisomal function and dysfunction.
