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.
Helicobacter pylori infection and germline genetic variants interacted with each other to affect the risk of gastric cancer in a study comparing more than 11,000 patients with stomach cancer and 44,000 people without cancer. Researchers from the RIKEN Center for Integrative Medical Sciences (IMS) published those findings in the March 30, 2023, issue of the New England Journal of Medicine.
Three papers accelerated through publication and appearing in Nature March 30, 2023, have linked an unexplained rise in cases of acute hepatitis in children to adeno-associated virus 2 (AAV2), and pointed to a possible immune-mediated trigger in patients who have a genetic predisposition.
The advance of antifungals – a class long needful of new therapies – continued with Scynexis Inc.’s potential $593 million exclusive license agreement with GSK plc for Brexafemme (ibrexafungerp), first cleared by the U.S. FDA in June 2021 and indicated for vulvovaginal candidiasis (VVC) as well as for reduction of recurrent VVC.
HIV infects immune cells, mainly CD4+ T cells. But they are not the only ones. It also settles in the genome of myeloid cells, monocytes or macrophages. According to a study from Johns Hopkins University, the viral DNA inserted into myeloid cells is functional. The virus also reactivated from the monocyte-derived macrophage reservoir. New cure strategies need to take these cells into account to eradicate the virus from the body.
Kaken Pharmaceutical Co. Ltd. and Bitbiome Inc. have entered into an agreement to collaborate on the creation of new drugs targeting infectious diseases with unmet medical needs.
COVID-19 complications involve activated T cells that contribute to inflammation. Foralumab, a fully human anti-CD3 monoclonal antibody, targets the T-cell receptor and regulates T-cell function to suppress inflammation. In a pilot trial, foralumab reduced lung inflammation, serum IL-6 and C-reactive protein in cases of moderate COVID-19.
