Two neutralizing monoclonal antibodies isolated from volunteers vaccinated against the yellow fever virus controlled the viremia and prevented severe disease and death in hamsters and primates.
Immunoprecise Antibodies Ltd.'s Talem Therapeutics LLC subsidiary has entered into a research collaboration and exclusive option license agreement with Xyphos Biosciences Inc., a wholly owned subsidiary of Astellas Pharma Inc.
Eureka Therapeutics Inc. has entered into a license agreement with the National Cancer Institute (NCI) to develop and commercialize a novel antibody targeting mesothelin (MSLN) in combination with Eureka's proprietary Artemis T-cell receptor platform.
Exevir Bio BV has announced research detailing a novel, highly potent, anti-S2 camelid single-domain antibody, discovered at the VIB-Ugent Center for Medical Biotechnology, and developed as a candidate drug molecule by Exevir as XVR-013.
Autoantibodies are typically not good news. But a group of researchers from Bellinzona, Switzerland, have observed that the presence of autoantibodies against chemokines, a special class of cytokines, is associated with mild disease and less risk of developing long COVID. “Our hypothesis was that antibodies to chemokines, if they existed, would also be associated with a negative outcome of the disease. But, what we found, in fact, was the exact opposite of what we were predicting,” Davide Robbiani, director of the Institute for Research in Biomedicine, told BioWorld.
Even its name is a testament to how enigmatic the tingible macrophage has been. Tingible, which means stainable, certainly gives no clues to its functions – but was, at least, one thing that was known about the cells. Now, scientists at the Garvan Institute of Medical Research have tracked the lifecycle and function of tangible macrophages in the lymph nodes, with implications for understanding autoimmune disorders, which are still poorly understood. Published March 2, 2023, in the journal Cell, the study highlights intravital imaging techniques the scientists used to observe how macrophages formed within the lymph nodes and how they behaved in real time.
A multi-institutional team of researchers has reported the development of an anti-IL-8 antibody against endometriosis using recycling antibody engineering technology. The study confirmed the role of the inflammatory cytokine IL-8 in the development of inflammation and fibrosis in endometriosis and showed that administration of IL-8 antibodies in primate models improved endometriosis pathology.
Maxion Therapeutics Ltd. has raised $16 million in a series A to take forward a new method for drugging G-protein coupled receptors (GPCRs) and ion channels with antibodies. The technology brings together naturally occurring knottin peptides that are derived from sources such as snake venom and which can engage GPCRs and ion channels, with antibodies that deliver them to these notoriously difficult, shape-shifting targets.
Ymmunobio AG has secured ownership of neuronal pentraxin receptor (NPTXR) antibodies after the company signed a transfer ownership agreement with Nagoya University for a license to NPTXR antibodies.
