An international research team may have found that a protein implicated in tumor growth may be able to help regulate awry cellular translation and protect against neuronal decay.

Cells translate their genetic material at rapid rates with exquisite precision to reproduce, repair damage or even combat disease. But the process can deregulate and give rise to disease...

3D-printed novel biomaterial mimics properties of living tissues. Imagine if surgeons could transplant healthy neurons into patients living with neurodegenerative diseases or brain and spinal cord injuries. And imagine if they could “grow” these neurons in the laboratory from a patient’s own cells using a synthetic, highly bioactive material that is suitable for 3D printing.

By discovering a new printable biomaterial that can mimic properties of brain tissue, Northwestern University researchers are now closer to developing a platform capable of treating these conditions using regenerative medicine.

A key ingredient to the discovery is the ability to control the self-assembly processes of molecules within the m...

Researchers from the Institut national de la recherche scientifique (INRS) have shown that nanoparticles could be used to deliver drugs to the brain to treat neurodegenerative diseases.

The blood-brain barrier is the main obstacle in treating neurodegenerative diseases such as Alzheimer and Parkinson. According to a recent study conducted by Jean-Michel Rabanel, a postdoctoral researcher under the supervision of Professor Charles Ramassamy, nanoparticles with specific properties could cross this barrier and be captured by neuronal cells...

Obstructing lymphatic vessels (in green) in a mouse model of Alzheimer’s disease significantly increased the accumulation of harmful plaques in the brain. “What was really interesting is that with the worsening pathology, it actually looks very similar to what we see in human samples in terms of all this aggregation of amyloid protein,” said researcher Jonathan Kipnis, PhD.

Faulty brain plumbing to blame in Alzheimer’s, age-related memory loss – and can be fixed. By improving the function of the lymphatic vessels, scientists at the University of Virginia School of Medicine have dramatically enhanced aged mice’s ability to learn and improved their memories...
