Combined Treatments Cure Muscular Dystrophy in Model

A new approach for generating functional muscle tissue from induced human pluripotent stem cells enabled replacement of muscle loss in a mouse model of Duchenne muscular dystrophy (DMD). More...

CRISPR/Cas9 Treatment Eases Symptoms in ALS Model

Neurodegenerative disease researchers treated a mouse model of amyotrophic lateral sclerosis with a modified adeno-associated virus that delivered the CRISPR/Cas9 gene-editing tool to the animals' neurons, where it disabled a malfunctioning gene. More...

Image: Three T-cells surround a cancer cell. New drugs, such as immune checkpoint inhibitors, can help the immune system attack cancer, but the drugs’ effectiveness depends on the patient’s genetic makeup (Photo courtesy of the U.S. National Institutes of Health).

Immune Checkpoint Inhibitor Effectiveness Dependent on HLA Diversity

Findings reported in a recently published paper suggested that an individual’s own genes controlled his or her response to immunotherapy drugs known as immune checkpoint inhibitors. More...

Novel Gene Therapy Based on Modified Version of CRISPR/Cas9 Tool

A modified form of the CRISPR/Cas9 gene-editing tool does not cause "double-strand breaks" (DSBs) in the DNA, yet it retains the ability to target and activate specific sites in the genome. More...

MicroRNA Treatment Prompts Cardiomyocyte Proliferation

Working with a variety of mouse models, heart diseases researchers showed that a hydrogel delivery system could release a specific microRNA at the site of injury following a myocardial infarction where it induced cardiomyocyte proliferation and tissue regeneration. More...

Light-Enhanced Microneedle Vaccine Prevents Melanoma Development

A novel immunotherapeutic vaccine prevented the development of skin cancer in a mouse model by exploiting the ability of the protein melanin to transform light energy into heat. More...
