At this week’s American Chemical Society Spring meeting, Galderma SA reported the discovery of novel, oral and selective macrocyclic inhibitors of protein kinase C θ (PKCθ) for the potential treatment of atopic dermatitis (AD) and psoriasis.
Researchers from Anew Therapeutics Pte Ltd. recently detailed the discovery of novel oral IL-17A small-molecule inhibitors as candidates for the treatment of psoriasis.
Atopic dermatitis (AD) is mainly triggered by immune dysregulation, barrier dysfunction and inflammation propagation, and chronic itching increases the susceptibility to infections.
Domain Therapeutics SA has nominated PAR2 antagonist DT-9046 as a drug candidate with potential to treat various inflammatory diseases, including atopic dermatitis, inflammatory bowel disease and arthritis, as well as neuroinflammatory conditions such as migraine.
In atopic dermatitis, psoriasis and other dermatologic diseases, T cells lose tolerance to self-antigens, triggering the autoimmune response that leads to abnormal skin cell proliferation and inflammation. The use of Nck modulators may help correct dysregulated T-cell receptor (TCR) signaling, potentially restoring immune tolerance and reducing subsequent inflammatory responses.
Maxion Therapeutics Ltd. has raised $72 million (£58 million) in a series A financing to support its development of antibody-based Knotbody drugs for ion channel- and G protein-coupled receptor (GPCR)-driven diseases.
APG-777 is an anti-IL-13 humanized monoclonal antibody (mAb) designed to block Th2 inflammatory signaling mediated by the IL-13Rα1/IL-4Rα complex, while APG-990 is a fully human anti-OX40L mAb that that blocks type 1/2/3 inflammatory signaling. Apogee Therapeutics Inc. is studying the combination effects of APG-777 and APG-990 as potential therapy for atopic dermatitis (AD).
Patients with psoriatic arthritis exhibit high levels of both IL-17A and IL-17F cytokines in the synovium. Bimekizumab, a biologic that targets both IL-17A and IL-17F, was recently approved for the treatment of plaque psoriasis and psoriatic arthritis.
To identify new genetic modifiers for epidermolysis bullosa simplex (EBS), a team led by scientists at Tel Aviv Medical Center performed exome sequencing of 195 patients with EBS from 90 different families, followed by screening for pathogenic variants in selected individuals, which resulted in identification of 3 variants in HMCN1 (codes for hemicentin-1) that co-segregated with the disease phenotype severity in 4 families.
Psoriasis is a chronic, recurrent and inflammatory skin disorder associated with immune system dysregulation. The abnormal immune response led to accelerated skin cell proliferation, resulting in thick plaques and chronic inflammation. The current gold-standard treatment is injectable immunosuppression.
