Complementarity-determining regions (CDRs) are relatively short peptide loops in antibodies where they bind to their specific antigens. Bovines, unlike humans and other vertebrates, rely on ultralong CDR H3 antibody knob regions to neutralize cryptic viral epitopes.

Researchers who follow their instincts and achieve slow results while trying to break barriers have little support. They replace it with persistence. This is the story of Katalin Karikó and Drew Weissman. What was once a dream in their minds was later a success.

Researchers who follow their instincts and achieve slow results while trying to break barriers have little support. They replace it with persistence. This is the story of Katalin Karikó and Drew Weissman. What was once a dream in their minds was later a success. Their work together for decades was essential to achieving mRNA vaccines, and their perseverance was rewarded today with the 2023 Nobel Prize in Medicine.

Modex Therapeutics Inc. has been awarded a contract from the Biomedical Advanced Research and Development Authority (BARDA) to advance a platform and specific candidates designed to address a range of public health threats in viral infectious diseases.

Viruses of the Betacoronavirus genus that bind to angiotensin-converting enzyme 2 (ACE2) are the coronaviruses posing the most significant pandemic risk. Sarbecoviruses of this genus caused the severe acute respiratory syndrome (SARS) epidemic and the SARS-CoV-2 pandemic. Therefore, new vaccines with broader protection from ACE2-binding sarbecoviruses and emerging variants of concern are urgently needed.
