Peptide 5

Description

Peptide5 is a connexin43 mimetic peptide. Reduces swelling, astrogliosis, neuroinflammation and neuronal cell death following spinal cord injury ex vivo and in vivo. Exhibits analgesic effects in models of neuropathic pain.

Uses

Peptide5, a connexin 43 mimetic peptide, reduce animals swelling, astrogliosis, and neuronal cell death after spinal cord injury[1]

in vitro

Peptide5, significantly reduces the degree of spinal cord injury (SCI) in a rodent ex vivo model. Peptide5 produces the more significant reduction in swelling and is analyzed further. Treatment with peptide5 reduced both the level of Cx43 and the number of glial fibrillary acidic protein (GFAP)-positive astrocytes, and at the same time reduces the loss of NeuN- and SMI-32–positive neurons in a concentration- and time-dependent manner.

in vivo
