Research at Abbvie Inc. and Calico Life Sciences LLC has led to the development of proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase binding moiety covalently linked to tyrosine-protein phosphatase non-receptor type 2 (PTPN2; TCPTP) and/or PTPN1B. They are reported to be useful for the treatment of cancer, type 2 diabetes and nonalcoholic steatohepatitis (NASH).
Cocrystal Pharma Inc., Merck Sharp & Dohme Corp. and MSD R&D (China) Co. Ltd. have jointly patented new cap-dependent endonuclease (CEN) (influenza virus) inhibitors that are reported to be useful for the treatment of influenza.
Allogeneic mesenchymal stromal cell (MSC) therapy is well tolerated in patients with graft-vs.-host disease (GVHD) but results in clinical trials have shown that it lacks potent immunosuppressive effects. Researchers from the Mayo Clinic thus proposed enhancing MSC immunosuppression by bioengineering the first chimeric antigen receptor (CAR) MSCs (CAR-MSCs) and targeting E cadherin (anti-Ecad CAR-MSC), with a CD28 intracellular signaling domain to induce antigen-specific immunosuppressor effect.
Primary sclerosing cholangitis (PSC) is a rare chronic and progressive autoimmune bile duct disease that is strongly associated with several immune-mediated disorders, the shared etiology and underlying characteristics of which is not completely understood. Researchers from Baylor College of Medicine investigated the shared genetic architecture of PSC with a variety of clinical and epidemiological traits and aimed to identify new lead PSC risk-associated loci.
Obesity is tied to airway hyperresponsiveness and lung fibrosis, which may lead to patients with asthma and obesity poorly responding to asthma therapy. Blocking proprotein convertase subtilisin/kexin type 9 (PCSK9) is known to reduce serum cholesterol levels and to exert anti-inflammatory effects.
