Cartalax

Cartalax — Cartilage & Connective-Tissue Peptide Bioregulator

Cartalax is a short synthetic peptide bioregulator most commonly described as the tripeptide Ala-Glu-Asp (AED); some suppliers market an Ala-Glu-Asp-Leu (AEDL) tetrapeptide under the same name. Part of the Khavinson family, it is researched for tissue-specific regulation of chondrocyte and connective-tissue gene expression.

Mechanism of Action

As an ultrashort peptide bioregulator of the Khavinson class, Cartalax is studied for a non-receptor, epigenetic-style mechanism. The peptide is small enough to be proposed to cross the cell and nuclear membranes and interact directly with DNA and chromatin, modulating the tissue-specific expression of genes associated with chondrocytes and connective tissue. This differs fundamentally from receptor-signaling peptides — the proposed activity is regulation of transcription rather than activation of a cell-surface receptor. Evidence is preclinical (cell-culture and animal models) from the originating research program.

Key Research Areas

🔬 Chondrocyte & Matrix Gene Expression

Studied in cell culture for effects on cartilage matrix genes, including type II collagen and proteoglycans such as aggrecan.

⏳ Cartilage & Joint Aging

Examined in animal models of cartilage degeneration and osteoarticular aging.

⏳ Cellular Aging

The AED peptide appears across gene-expression and aging studies in multiple cell types (fibroblasts, mesenchymal and neuronal stem cells).

🩹 Connective-Tissue Inflammation

Investigated for inflammatory-signaling markers in tendon, ligament and intervertebral-disc research contexts.
