Application

10Panx1 trifluoroacetate salt has been used as the selective pannexin-1 mimetic inhibitory peptide to study the involvement of pannexin-1 in praliciguat (PRL) inhibition of the NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasome.

Biochem/physiol Actions

Reversible pannexin-1 (panx1) channel blocker that inhibits P2X7R substrate uptake and protects neurons against NMDAR overactivation.
The pannexin-1 (panx1) extracellular sequence-derived 10panx1 functions as a reversible panx1 channel blocker (IC50 = 52 μM; human panx1-overexpressing HEK cells) that effectively inhibits ATP-induced dye-uptake in panx1 HEK cells co-expressing rat or human P2X7R (IC50 = 93 μM), as well as in murine J774 and human alveolar macrophages (Effective conc. 100-200 μM). 10panx1 (100 μM) is shown to protect rat hippocampal neurons against death induction upon NMDAR overactivation by excitotoxic concentrations of NMDA (100 μM) in cultures and ameliorate withdrawal symptoms among morphine-treated rats in vivo (10 μg/rat via intrathecal injection).

Overactivation of neuronal N-methyl-D-aspartate receptors (NMDARs) causes excitotoxicity and is necessary for neuronal death. In the classical view, these ligand-gated Ca(2+)-permeable ionotropic receptors require co-agonists and membrane depolarization for activation. We report that NMDARs signal during ligand binding without activation

In Alzheimer's disease (AD), astrocyte properties are modified but their involvement in this pathology is only beginning to be appreciated. The expression of connexins, proteins forming gap junction channels and hemichannels, is increased in astrocytes contacting amyloid plaques in brains

Pannexin-1 (Px1) is expressed at postsynaptic sites in pyramidal neurons, suggesting that these hemichannels contribute to dendritic signals associated with synaptic function. We found that, in pyramidal neurons, N-methyl-d-aspartate receptor (NMDAR) activation induced a secondary prolonged current and dye flux

Systemic hypertension is a risk factor of age-related macular degeneration (AMD), a chronic inflammatory disease. Acute hypertension is caused by increased extracellular osmolarity after intake of dietary salt (NaCl). We determined in cultured human retinal pigment epithelial (RPE) cells whether

We show here that the growth factor FGF-1 is proinflammatory in the spinal cord and explore the inflammatory mechanisms. FGF-1 applied to rat spinal astrocytes in culture initiates calcium signaling and induces secretion of ATP that within minutes increases membrane
