Identification of chemokines and cytokines offers new hope for inflammatory myopathy patients

10.09.2002


The inflammatory myopathies comprise three different entities: polymyositis, inclusion body myositis and dermatomyositis. People in all age groups can be affected by major muscle weakness and pain, and show evidence of muscle fiber breakdown in the serum. Autoimmune pathogenetic mechanisms have been identified in each inflammatory myopathy, but the antigen(s) recognized by the autoreactive inflammatory cells and the factors eliciting the aberrant immune responses remain unknown. Currently, patients are treated with corticosteroids with variable success rates and at a high cost of side-effects.



The ongoing research is aimed at identifying the factors that guide the trafficking of inflammatory cells from the blood to the inflamed muscle tissue. A new study reports the differential expression of chemokines and their receptors in each inflammatory myopathy. Chemokines represent a family of small-molecular weight cytokines that have an important role in the migration of distinct leukocyte subsets to the sites of inflammation. The chemokines monocyte chemoattractant protein-1 (MCP-1) and stromal derived factor (SDF-1a and SDF-1b) and their receptors are strongly expressed whereas a number of others are undetectable.

Blocking the autoimmune cascade by targeting chemokines or chemokine receptors has given excellent results in animal models of other immune diseases. The present work identifies the candidates for selective immune intervention in patients suffering autoimmune inflammatory myopathies and may well lead to more selective treatment modalities with less side-effects than the currently available drugs.


Previous research by this group had focused on other factors that control recruitment and activation of immune cells, such as cell adhesion molecules and cytokines. Based in part on data that described the role of the cytokine tumor necrosis factor-a (TNF-a) and its receptors in inflammatory myopathy muscle biopsies, preliminary clinical studies with TNF-blocking monoclonal antibodies are now being initiated in several hospitals. "It is very encouraging to see data obtained from clinically oriented research move from the laboratory bench to the clinical treatment phase in just a few years time", said Professor Jan De Bleecker who is the first author of these papers.

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
