Collagenase-2 is a member of a protein family called matrix metalloproteinases (MMPs, collagenase-2 is MMP8), a large group of enzymes that break down collagen and other components of the body's connective tissue. MMPs have been implicated in contributing to MS by degrading the tissue that maintains the blood-brain barrier, thus allowing unwanted cells to invade and break down nerves. In fact, MMPs are found in elevated amounts in the blood and spinal fluid of diseased individuals.
Using a mouse model of MS, Carlos Lopez-Otin and colleagues performed two analyses on MMP8 to determine how relevant this protein is to the disease. First, they developed mutant mice deficient in the gene for MMP8 and found that these mice had a fewer invading cells in the brain, fewer damaged nerves, and a general improvement in their clinical profile.
They also gave diseased mice a drug that blocked MMP8 activity and found that this, too, could reduce the severity of disease symptoms. Taken together, these promising findings provide the first causal evidence for MMP8 in the development of MS, and offer a new therapeutic target.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
