Research profile

Vesugen research profile

Vesugen is the name used for the synthetic tripeptide Lys-Glu-Asp (KED), coded T-38 in some papers. It was developed by V. Kh. Khavinson's group, and KED has been studied in thymus, fibroblast, stem-cell and neuronal cultures and in a mouse model of Alzheimer's disease.

Published research

  • Human embryonic thymus cell cultures: Ki-67, p53 and Mcl-1 expression and CD4/CD8 profiles measured after exposure to T-38 (KED) and T-32 (Khavinson et al., J Amino Acids, 2011).
  • Aging cell cultures: skin fibroblast markers (Lin'kova et al., Bull Exp Biol Med, 2016) and IGF1, FOXO1, TERT, TNKS2 and NFκB expression in human mesenchymal stem cells (Ashapkin et al., Mol Biol Rep, 2020).
  • Neuronal models: mushroom-spine counts in mouse hippocampal neurons under amyloid synaptotoxicity (Kraskovskaya et al., Bull Exp Biol Med, 2017) and dendritic-spine measures in 5xFAD mice (Khavinson et al., Pharmaceuticals, 2021).
  • Review of KED and gene expression in neurogenesis, including p16, p21, NES, GAP43, APOE and IGF1 (Khavinson, Lin'kova & Umnov, Bull Exp Biol Med, 2021).

Frequently asked questions

What is the sequence of Vesugen?

Lys-Glu-Asp (KED), a tripeptide with a molecular weight of about 390.4 g/mol.

What is T-38?

T-38 is the code used for the KED tripeptide in Khavinson-group thymus cell culture work.

How do I verify my lot?

Scan the QR code on the vial. It opens the certificate of analysis for that lot, with HPLC purity and the mass spectrometry identity result.
