In the tumor microenvironment, cancer cells activate various signaling pathways to promote their growth. This includes the formation of blood vessels. However, the circulatory system is not the only one attracted to the tumor. Researchers at Sanford Research have uncovered a mechanism to circumvent the immune response that would destroy them.
Casi Pharmaceuticals Inc. announced the U.S. FDA has cleared its IND application for CID-103, a monoclonal antibody targeting CD-38 for the prevention of antibody-mediated rejection (AMR) of kidney allografts. The company plans to initiate a phase I study in adults with active and chronic active renal allograft AMR.
In a recent study in the Journal of Translational Medicine, researchers from Azrieli Research Center (Canada) and collaborating institutions hypothesized that the dysregulation of SMPDL3B may be involved in myalgic encephalomyelitis (ME) progression, and investigated its role and clinical relevance in ME pathophysiology.
Chinese scientists have discovered a common mechanism by which structurally distinct proteins elicit an allergic reaction, showing they cause the formation of pores in epithelial airway cells. That allows calcium ions to enter and trigger a type II immune cascade, which results in the release of histamine from mast cells.
Bristol Myers Squibb Co. has prepared and tested proteolysis targeting chimera (PROTAC) compounds comprising an E3 ubiquitin ligase-binding moiety coupled to interleukin-1 receptor-associated kinase 4 (IRAK-4) targeting moiety through a linker reported to be useful for the treatment of autoimmune diseases and inflammatory disorders.
Immunitas Therapeutics Inc. has revealed preclinical data supporting development of its potentially first-in-class, fully human anti-CD161 antibody, IMT-380. CD161-expressing T-cell subsets have been implicated in autoimmune diseases due to their production of inflammatory cytokines and presence in inflamed tissues.
Bacteria also defend themselves against pathogen attacks using mechanisms like those of the immune system. But if there is a system to repel an attack, it can also be dismantled. Scientists at the University of Southampton have described the components of Kiwa, a protein complex that blocks the entry of phage DNA, which are viruses that infect bacteria. They have also uncovered how Kiwa interacts with other bacterial defense strategies.
Formation Bio Inc. has licensed worldwide rights to Imidomics Inc.’s potentially first-in-class anti-CD226 monoclonal antibody (mAb). The program has received IND clearance and will be advanced by Formation Bio in autoimmune indications, starting with ulcerative colitis.
F. Hoffmann-La Roche Ltd. and Hoffmann-La Roche Inc. have discovered new heteroarylphenyl ether derivatives acting as cyclin-dependent kinase CDK8/cyclin C inhibitors. As such, they are reported to be useful for the treatment of graft-vs.-host disease, transplant rejection, multiple sclerosis, rheumatoid arthritis, atopic dermatitis, psoriasis, amyotrophic lateral sclerosis and stroke, among others.
The autoimmune disorder systemic lupus erythematosus (SLE) involves upregulation of IgD, and studies have shown that anti-IgD antibodies can alleviate the autoimmune disorder rheumatoid arthritis in mouse models. Building on this finding, researchers in Hefei and Changshu, China, have shown that interrupting the interaction between IgD and its receptor FcδR can reduce cytokine levels and phosphorylation of JAK2 and STAT3, suppressing the activation and proliferation of CD4+ T cells in SLE.
