Most cells have a pretty normal life: they’re born, they grow, they get old, and they die. But the Benjamin Buttons of the cellular world can go from old to young again in the right context.
Researchers at Ruhr-Universität Bochum have been studying the role of the two proteins tenascin C and tenascin R in multiple sclerosis. In this disease, cells of the immune system destroy the myelin sheaths, i.e. the sheaths of the nerve cells.
Osteoarthritis – a painful condition that results from the deterioration of the cartilage in our joints – affects millions of people worldwide. To combat this issue, NIBIB-funded researchers are developing an implantable, biodegradable film that helps to regenerate the native cartilage at the site of damage. Their study, performed in rabbits, could be an initial, important step in the establishment of a new treatment for this common condition.
A $2.3 million National Institutes of Health (NIH) grant will fund Jianjun Guan and Fuzhong Zhang’s effort to develop and deliver therapeutic proteins to help treat injured limbs.
Every species, from bacteria to humans, is capable of regeneration. Regeneration is mediated by the molecular processes that regulate gene expression to control tissue renewal, restoration and growth.
The research found that photobiomodulation – a form of low-dose light therapy – sped up recovery from burns and reduced inflammation in mice by activating endogenous TGF‐beta 1, a protein that controls cell growth and division.
The technique used in this preclinical study could aid tissue regeneration following severe accidents, surgical resections, or progressive muscle loss due to age or genetic disease.
