neurons producing a protein

What causes the death of neurons in Parkinson’s disease is still unknown. A recent study from Columbia University researchers suggests that neurons may be mistaken for alien intruders and attacked by the person’s own immune system. This would be similar to the way autoimmune diseases such as celiac disease, type I diabetes, and multiple sclerosis attack the body’s cells.

omalizumab strawberry allergy

The asthma drug omalizumab speeds up the desensitizing of patients with food allergies to multiple foods at once, researchers at Stanford have shown.

Another recent study by the same team showed people with multiple food allergies can be desensitized to several foods at once. Both of these phase-1 safety trials give the first evidence for a potential new method of treating people for multiple food allergies.

Researchers found that patients who took the »

ectopic neurons

Manipulating astrocyte support cells in the brain may offer a promising new way to treat Parkinson’s disease, research from University of Rochester shows.

The findings, using an animal model of the disease, reveal that a single therapy could concurrently repair multiple types of neurological damage caused by Parkinson’s, giving benefits that have not been seen in other methods.

“One of the central challenges in Parkinson’s disease is that many different cell types are damaged, each of which is of »

Nerves in mouse skin that are actively responding to the painful stimulus capsaicin

Two molecules involved in perpetuating chronic pain have been identified by researchers at The Johns Hopkins University and the University of Maryland.

Opening the way to potential advances in pain treatment, the molecules also look to have a role in causing uninjured areas of the body to be more sensitive to pain when a nearby area has been hurt.

Shown above, mouse skin nerves actively responding to painful stimulus have been genetically engineered to glow green, while hairs are in yellow.


sunlight nitric oxide

Exposing skin to sunlight changes levels of the messenger molecule nitric oxide in the skin and blood, lowering blood pressure, according to new research from the Universities of Southampton and Edinburgh.

“Nitric oxide along with its breakdown products, known to be abundant in skin, is involved in the regulation of blood pressure,” said University of Southampton professor Martin Feelisch. “When exposed to sunlight, small amounts of nitric oxide are transferred from the skin to the circulation, lowering blood vessel tone; as blood pressure drops, so does the »
