General description

TLQP-21 peptide is a derivative of VGF and is expressed at higher levels in the brain.[1]

Biochem/physiol Actions

TLQP-21 peptide is involved in the central and peripheral nervous system activities such as regulating reproductive and circadian behaviors, feeding, and body weight. It is also involved in regulating neuropathic pain and peripheral adiposity.[1] TLQP-21 plays a role in stimulating the secretion of insulin and prevents apoptosis of pancreatic cells.[2] It also activates the complement C3a receptor-1 (C3aR1) in the brain.[1]

Physical form

Lyophilized from 0.1% aqueous TFA

    Hyperglycemia causes oxidative stress that could damage vascular endothelial cells, leading to cardiovascular complications. The Vgf gene was identified as a nerve growth factor-responsive gene, and its protein product, VGF, is characterized by the presence of partially cleaved products. One

    Vgf gene expression has been detected in various endocrine and neuronal cells in the gastrointestinal tract. In this study we investigated the pharmacological activity of different VGF-derived peptides. Among these, TLQP-21, corresponding to the 556-576 fragment of the protein was

    The vgf gene has been identified as an energy homeostasis regulator. Vgf encodes a 617-aa precursor protein that is processed to yield an incompletely characterized panel of neuropeptides. Until now, it was an unproved assumption that VGF-derived peptides could regulate

    Mesenchymal stem cell (MSC) transplantation has been widely applied as a potential therapeutic for multiple diseases. However, the underlying therapeutic mechanisms are not fully understood, especially the paradox between the low survival rate of transplanted cells and the beneficial therapeutic
