In Vitro

BMS-986126 demonstrates similar, nanomolar potency (IC50: 135-456 nM) against multiple MyD88-dependent TLRs (TLR2/5/7/9) in human PBMCs, as well as potent inhibition of both NF-κB-regulated (IL-6) and type I IFN (IFN-α) responses, extending to cytokines induced by IL-1β and IL-18[1].
BMS-986126 fails to significantly affect cytokine production induced by the MyD88-independent agonists TLR3 and TNF-α[1].
BMS-986126 (0-2 μM, 30 min) dose-dependently inhibits the phosphorylation of IKKα/β and ERK downstream of TLR2 and TLR4, and ERK downstream of TLR7 in human PBMCs[1].
BMS-986126 demonstrates equivalent potency in inhibiting TLR7/9-induced interferon response gene expression (e.g., IFIT1) in PBMCs from both healthy donors and patients with SLE[1].
BMS-986126 (5 μM, 30 min) broadly reverses the gene expression profile induced by TLR7 activation in human PBMCs, with a significant proportion of the inhibited genes being canonical interferon-stimulated genes[1].
BMS-986126 (16-80 nM, 30 min) exhibits a synergistic effect with Prednisolone (HY-17463) in suppressing TLR9-induced and flu virus-induced IFIT1 expression in human PBMCs, showing significantly greater inhibition than either single agent[1].

BMS-986126 (0.1-3 mg/kg, p.o., single dose 30 min pre-LTA/CpG-ODN/Gardiquimod) inhibits cytokine production downstream of multiple MyD88-dependent TLRs (TLR2/7/9) in mice[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
