At the ongoing International Society for Stem Cell Research meeting, Chinese researchers reported they demonstrated that SPT6 homolog, histone chaperone and transcription elongation factor (SPT6) promotes epidermal stem/progenitor cells differentiation by facilitating transcriptional elongation, but its role in vivo in skin homeostasis is not well defined.
Regulatory T cells (Tregs) maintain immune homeostasis by inhibiting excessive immune responses. Dysregulation of Tregs, characterized by reduced cell numbers or impaired suppressive function, is implicated in the pathogenesis of autoimmune diseases. Low-dose interleukin-2 (IL-2) therapy expands Tregs and enhances their suppressive capacity while minimizing the activation of T cells and natural killer (NK) cells.
Monte Rosa Therapeutics Inc. has gained IND clearance from the FDA for MRT-8102, a NEK7-directed molecular glue degrader being developed to treat inflammatory conditions linked to NLRP3, IL-1β and IL-6 dysregulation.
Persistent activation of the stimulator of interferon genes (STING), resulting from aberrant metabolism or mutations in STING1, can lead to inflammatory damage and autoimmune diseases. Therefore, inhibiting STING activity may offer therapeutic potential for treating these disorders.
Sanofi SA has exercised its option to exclusively license Nurix Therapeutics Inc.’s STAT6 program, including the drug development candidate NX-3911, an oral, highly selective STAT6 degrader.
Recludix Pharma Inc. has nominated a lead development candidate, REX-8756, an oral, selective and reversible small-molecule inhibitor of STAT6, and completed GLP toxicology studies for the compound. REX-8756 has potential for patients with type 2 immune-related inflammatory diseases.
A peptide with a dual mechanism of action – it dissolves the bacterial membrane and activates the immune system – could be an effective weapon against microorganisms that have evolved ways to evade antibiotics, as superbugs do. Scientists at the University of Pennsylvania (UPenn) have designed stable synthetic peptides that activate mast cell receptors, which are cells involved in the innate and adaptive immune response. This dual approach eliminates bacteria and recruits neutrophils to finish the job.
Mayo Foundation for Medical Education and Research (MFMER) and University of Florida have identified atrial natriuretic peptide B (NPR2; guanylate cyclase B) receptor positive allosteric modulators (PAMs) reported to be useful for the treatment of fibrosis.
Activation of the α7 nicotinic acetylcholine receptor may be therapeutically useful against acute lung injury by suppressing expression of pro-inflammatory genes.
Arcus Biosciences Inc. has identified mast/stem cell growth factor receptor Kit (KIT; c-Kit; CD117) inhibitors reported to be useful for the treatment of cancer, allergy, autoimmune, inflammatory, cardiovascular, metabolic, dermatological and respiratory disorders, among others.
