Crystagen

Also known as: Crystagen

Crystagen is a short synthetic immunomodulatory peptide bioregulator (Glu-Trp-Ala-Glu) developed in the Khavinson family of peptides and studied for normalizing immune function.

Last updated

Mechanism of Action

Crystagen is a tetrapeptide bioregulator proposed to act as a gene-regulating peptide that penetrates cells and binds DNA to modulate expression of genes involved in immune-cell differentiation and function. It is reported to influence thymic and lymphoid tissue activity, supporting normalization of T-cell populations and cytokine balance. As with other Khavinson peptides, its proposed mechanism centers on epigenetic-style regulation that restores age- or stress-impaired immune homeostasis, though human mechanistic data are limited.
