Friedreich's ataxia -- an effective gene therapy in an animal model

A gene therapy approach using adeno-associated virus (AAV) successfully treated heart disease in mice with Friedreich's ataxia, restoring full functionality to the hearts. The treatment, which introduced a normal copy of the FXN gene, prevented the development of heart disease and even fully cured advanced-stage cases.

From mouse ears to man's?

Researchers at Tel Aviv University have discovered that DNA therapy can preserve inner ear nerve cells in humans with certain types of progressive hearing loss. The study uses a protein growth factor to block degeneration and has important implications for enhancing sound perception with cochlear implants.

Pioneer Award recipients Marina Cavazzana and Adrian Thrasher recognized for advancing gene therapy to the clinic for immunodeficiency disorders

Marina Cavazzana and Adrian Thrasher have been honored with the Pioneer Award for basic and clinical gene therapy for immunodeficiency disorders. They are pioneers in treating life-threatening inherited diseases of the immune system with gene therapy, using a patient's own modified stem cells.

Electroacupuncture effect on depression and variation of polygenes expression

Researchers used a rat genomic gene-chip to profile hippocampal gene expression changes after electroacupuncture therapy. The results showed that electroacupuncture regulates the expression of specific genes involved in depression, including Vgf and Igf2. These findings suggest that electroacupuncture may be a useful treatment for depr...

Gene therapy for lysosomal storage disease shown to be safe and well tolerated

A new gene therapy approach has been shown to be safe and well-tolerated in a clinical trial of four children with mucopolysaccharidosis type IIIA, an inherited lysosomal storage disease. The treatment involved delivering therapeutic genes via an adeno-associated viral vector, resulting in improved brain shrinkage and behavioral changes.

The nose knows in asthma

Researchers have discovered that genes expressed in the nasal passages can serve as accurate proxies for those expressed deeper in the lungs. This breakthrough allows for less invasive and more affordable genetic profiling of asthmatic patients, potentially leading to improved treatment options and better understanding of the disease.

Can personalized tumor vaccines improve interleukin-2 treated metastatic melanoma?

A new study found that combining high-dose interleukin-2 therapy with personalized tumor cell-based immunotherapy significantly improves patient survival rates. The treatment approach, which activates patients' immune systems using their own tumor cells, outperforms IL-2 alone in extending survival.

Does the body's immune response to viral vector delivery systems affect the safety or efficacy of gene therapy?

A recent study published in Human Gene Therapy evaluated the immune response to viral vector delivery systems and their impact on gene therapy's safety and efficacy. The researchers found that the systemic and local immune reactions induced by AAV-based gene therapy did not affect the safety of gene therapy or expression of the replace...

New mechanism that permits selective capture of microRNAs in nanovesicles that shuttle between cells

A new study describes a mechanism by which microRNAs are encapsulated and exported in nanovesicles, facilitating intercellular communication. The researchers identified EXOmotifs, specific nucleotide sequence patterns, that enable the export of miRNAs from human T lymphocytes.

A*STAR scientists discover novel hormone essential for heart development

Researchers at A*STAR's Institute of Medical Biology and Institute of Molecular and Cellular Biology have identified a gene encoding a hormone called ELABELA, which is crucial for heart formation in zebrafish embryos. The discovery holds great promise for the development of targeted therapies for heart disease and blood pressure control.

New study finds no benefit to selecting dose of blood thinner based on patients' genetic makeup

A new study published in the New England Journal of Medicine found that a gene-based method for selecting warfarin doses has no added benefit over standard dosing methods. However, African Americans patients showed better outcomes with non-genetic strategy, highlighting the need for further research on personalized medicine approaches.

Persistent gene therapy in muscle may not require immunosuppression

Researchers found that a gene therapy approach using rAAV vectors can promote a regulatory immune response, allowing for sustained gene expression in muscle tissue without the need for immunosuppression. The study used M-type α-1 antitrypsin (M-AAT) and demonstrated long-term expression in patients with AAT deficiency.
