What is the T7 Peptide?
The T7 peptide is a well-characterized sequence known for its high affinity toward the transferrin receptor (TfR). Specifically, T7 is a seven-peptide ligand of transferrin receptors (TfR), which plays a pivotal T7 Peptide-modified macrophage membrane-coated role in how molecules interact with the endothelial cells that form the structural integrity of the blood–brain barrier. By mimicking the natural transferrin protein, this peptide can engage with TfR, potentially facilitating pathways that bypass traditional cellular exclusion mechanisms.
