Description

LQVTDSGLYRCVIYHPP (LP17) is a triggering receptor expressed on myeloid cells (TREM-1) inhibitory peptide. LQVTDSGLYRCVIYHPP substantially alleviates ischemia-induced infarction and neuronal injury. LQVTDSGLYRCVIYHPP can get access into brain and block TREM-1[1].

IC50 & Target

TREM-1[1]
In Vitro

LQVTDSGLYRCVIYHPP (LP17) (1 or 10 μM; 24 h) substantially decreases mRNA levels of pro-inflammatory cytokines and chemokines after reoxygenation and remarkably attenuates extracellular protein levels of IL-1β and IL-18 in a microglia oxygen-glucose deprivation (OGD) model[1].
LQVTDSGLYRCVIYHPP (LP17) (10 μM; 24 h) interacts with microglial SYK[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

LQVTDSGLYRCVIYHPP Related Antibodies

RT-PCR[1]

Cell Line: Primary microglia
Concentration: 1 or 10 μM
Incubation Time: 24 h
Result: Decreased mRNA levels of NLRP3, IL-1β, IL-18, IL-6, CD16, CD32, iNOS, MCP-1, CXCL-1, and CXCL-2 after reoxygenation.

Western Blot Analysis[1]

Cell Line: Primary microglia
Concentration: 10 μM
Incubation Time: 24 h
Result: Suppressed ischemia/reperfusion-induced increments in CARD9, p-p65 in CARD9/NF-κB signaling and NLRP3, ASC, cleaved caspase-1, mature IL-1β, and mature IL-18 in NLRP3/caspase-1 signaling in a microglia oxygen-glucose deprivation (OGD) model.
In Vivo

LQVTDSGLYRCVIYHPP (LP17) (0.5 or 1 mg/kg; intranasal; daily for 3 days) alleviates ischemia-induced infarction and neuronal injury in mice[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Adult male C57BL/6J mice (20-25 g), mice cerebral ischemia/reperfusion (I/R) model induced by middle cerebral artery occlusion (MCAO)[1]
Dosage: 0.5 mg/kg or 1 mg/kg
Administration: Intranasal administration, once daily for 3 consecutive days after MCAO
Result: Abolished ischemia-induced TREM-1 elevation at 1 mg/kg. Significantly reduced infarct volume by 27.3%, induced a markedly reduction in TUNEL positive cells and FJC positive neurons at 1 mg/kg. Rescued neurological deficits and cognitive dysfunction of MCAO mice. Inhibited microglial M1 polarization and neutrophil infiltration.

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.
