Summary
Mucopolysaccharidoses (MPS) are inherited diseases causing GAG buildup. Gene therapy offers a promising new treatment strategy for these severe pediatric conditions, addressing limitations of current therapies.
Area of Science:
- Biochemistry
- Genetics
- Pediatrics
Background:
- Mucopolysaccharidoses (MPS) are inherited lysosomal storage diseases in children.
- Enzyme deficiencies lead to glycosaminoglycan (GAG) accumulation, causing multisystemic symptoms and reduced lifespan.
- Current treatments like enzyme replacement therapy (ERT) and hematopoietic stem cell transplant (HSCT) have limitations, especially for neurological aspects.
Purpose of the Study:
- To review emerging gene therapy and gene-editing approaches for MPS.
- To discuss the potential of these novel strategies in overcoming current treatment challenges.
Main Methods:
- Review of pre-clinical and clinical research on gene therapy vectors for MPS.
- Analysis of gene-editing technologies being developed for MPS treatment.
Main Results:
- Gene therapy is an emerging strategy for MPS treatment.
- Various vectors and gene-editing approaches are under development.
- These novel therapies aim to improve efficacy, particularly for neurological symptoms.
Conclusions:
- Gene therapy and gene editing represent promising therapeutic avenues for MPS.
- Further research and clinical development are crucial to realize the full potential of these strategies for improving patient outcomes.

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.
