Patients suffering from B-cell lymphomas can be treated with antibodies directed against the B-lymphocyte antigen CD20. This therapy is not a cure, however, and new treatments that kill B-cells through different mechanisms are required, especially for patients with indolent lymphoid malignancies.
An alternative clinical target for B-cell lymphoma is CD22, a B-cell-specific member of the sialic acid binding Ig-like lectin (Siglec) family that recognizes α2,6-linked sialylated glycans as ligands. When it was demonstrated that B-cell activation can be down-regulated with sialosides, an intensive search for low-molecular-weight high-affinity ligands was initiated.
A collaborative research effort led by Beat Ernst and colleagues at the University of Basel in Switzerland has identified selective and high-affinity CD22 antagonists, and their results are reported in ChemMedChem.
Using surface plasmon resonance, the team screened an existing library of antagonists (which were initially designed for another member of the Siglec family) for binding affinity toward CD22. The initial hit was then optimized to yield a series of CD22 antagonists with nanomolar binding affinity. Ernst's research group will next examine the potential application of these CD22 antagonists in cell depletion therapy.Author: Beat Ernst, Universität Basel (Switzerland), http://www.pharmazentrum.unibas.ch/ernst.html

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
