Figure Lengend Snippet: a diABZI-i inhibits cGAMP-induced IFNβ in PBMCs ( n = 3 | 1 donor) and diABZI-a1 induces IFNβ in PBMCs ( n = 3 | 3 donors, representative donor displayed). Data represented as mean with SD in graph. Source data are provided as a Source Data file. b Superposition of crystal structures (side view) of STING bound to diABZI-a1 (gray) and diABZI-i (purple). c diABZI-a1 and diABZI-i superposition over the STING binding pocket. d Cartoon depicting apical wing distance and beta sheet lid between STING monomers. e Superposition of crystal structures (top view) of STING bound to diABZI-a1 (gray) and diABZI-i (purple). f THIQi inhibits cGAMP-induced IFNβ in PBMCs ( n = 3 | 1 donor). Data represented as mean with SD in graph. Source data are provided as a Source Data file. g Crystal structure overlay (top view) of STING bound to THIQi (orange) and diABZI-i (purple). h Apical wing distance measurements from structures in this study and reference structures collected from the PDB.
Article Snippet: Frozen human peripheral blood mononuclear cells (PBMCs, BioIVT) are gently thawed, suspended in complete medium [AIMV, 10% heat-inactivated FBS, 1% antibiotic-antimycotic, 1% sodium pyruvate, 1% MEM non-essential amino acids; ThermoFisher] and concentrated by low-speed centrifugation (400 × g, ambient temperature, five minutes).
