The scorpion and its tail

A chemical found in the arachnid's killer sting at the end of its tail reduces symptoms of arthritis without any side effects, say scientists

There can be no doubt that this discovery offers hope of a new drug that may prevent the agonising swelling and stiffness suffered by patients in their knees, hips and hands.

Molecular physiologist Professor Christine Beeton, of Baylor College of Medicine, Houston, has a full explaination:
"Rheumatoid arthritis is an autoimmune disease - one in which the immune system attacks its own body.

"In this case, it affects the joints. Cells called fibroblast-like synoviocytes (FLS) play a major role in the disease.

"As they grow and move from joint to joint, they secrete products that damage the joints and attract immune cells that cause inflammation and pain.

"As damage progresses, the joints become enlarged and are unable to move."
