Recent trends in mucopolysaccharidosis research

Area of Science:

• Biochemistry
• Genetics
• Neurology

Background:

• Mucopolysaccharidosis (MPS) comprises inherited metabolic disorders stemming from lysosomal enzyme deficiencies.
• These deficiencies lead to glycosaminoglycan (GAG) accumulation, causing multisystemic symptoms.
• Pathophysiology involves impaired autophagy, neuroinflammation (microglia, astrocytes), and tauopathy.

Purpose of the Study:

• To review recent advancements in Mucopolysaccharidosis (MPS) research.
• To discuss the underlying pathophysiological mechanisms of MPS.
• To outline strategies for developing improved therapeutic approaches.

Main Methods:

• Literature review of recent MPS research.
• Analysis of pathophysiological mechanisms including autophagy, neuroinflammation, and tauopathy.
• Examination of emerging therapeutic strategies.

Main Results:

• Identification of new inherited metabolic errors with MPS features.
• Development of novel therapies targeting MPS, including blood-brain barrier-penetrating enzymes.
• Advancements in hematopoietic stem cell transplantation and gene-based therapies (viral vectors, gene editing).

Conclusions:

• MPS research is rapidly evolving, with a deeper understanding of its complex pathophysiology.
• Innovative therapeutic strategies show promise for improving patient outcomes.
• A strategic framework is needed to guide future MPS research and treatment development.
