Researchers at Columbia University College of Dental Medicine have developed an exosome-based platform, “safeEXO-Cas,” that significantly enhances the delivery of CRISPR/Cas9 genome editing components to specific cells and tissues.

CRISPR/Cas9 is a unique technology that enables geneticists and medical researchers to edit parts of the genome by removing, adding or altering sections of the DNA sequence. The study, published in Theranostics, demonstrates the potential of this innovative platform to revolutionize gene therapy and precision medicine.

The research, led by Dr...

What’s going on in our Brains when we Plan? Study uncovers how Mental Simulations rely on Stored Memories

In pausing to think before making an important decision, we may imagine the potential outcomes of different choices we could make. While this “mental simulation” is central to how we plan and make decisions in everyday life, how the brain works to accomplish this is not well understood.

An international team of scientists has now uncovered neural mechanisms used in planning. Its results, published in the journal Nature Neuroscience, suggest that an interplay between the brain’s prefrontal cortex and hippocampus allows us to imagine future outcomes in order to guide our decisions.

“The prefrontal cortex acts as a ‘simulator,’ mentally testing out possible actions using a cognitive map stored in the hippocampus,” explains Marcelo Mattar, an as...

Epstein-Barr Virus and Brain Cross-reactivity: Possible mechanism for Multiple Sclerosis detected

The role that Epstein-Barr virus (EBV) plays in the development of multiple sclerosis (MS) may be caused by a higher level of cross-reactivity, where the body’s immune system binds to the wrong target, than previously thought.

In a new study published in PLOS Pathogens, researchers looked at blood samples from people with MS, as well as healthy people infected with EBV and people recovering from glandular fever caused by recent EBV infection.

The study investigated how the immune system deals with EBV infection as part of worldwide efforts to understand how this common virus can lead to the development of multiple sclerosis, following 20 years of mounting evidence showing a...

Researchers Unveil Pioneering Approach to Combat Age-Related Vision Loss

Cirrus Therapeutics, the University of Bristol, and London’s Global University Institute of Ophthalmology have discovered a new treatment for age-related macular degeneration (AMD), the leading cause of vision loss among older adults.

Featured on the cover of the journal Science Translational Medicine, this research reveals that boosting a specific protein, IRAK-M, in retinal cells could offer a new and highly effective therapy for AMD.

AMD can severely impact a person’s vision. Patients suffering from AMD often start with blurred vision or seeing a black dot in their central vision, which can ultimately expand to the point where there is no useful central vision...
