The peroxisome: an update on mysteries 3.0

Area of Science:

• Cell Biology
• Biochemistry
• Human Health

Background:

• Peroxisomes are dynamic oxidative organelles crucial for lipid metabolism (fatty acid beta-oxidation, myelin sheath lipid synthesis) and redox balance.
• Dysfunctional peroxisomes lead to severe human metabolic disorders.
• Peroxisomes also play significant roles in immune and defense mechanisms against pathogens and viruses.

Purpose of the Study:

• To provide an updated review of peroxisome biology, building upon previous articles.
