Fibroblast Activation Protein

Fibroblast Activation Protein (FAP) is an enzyme found on certain cells involved in tissue remodeling and repair, particularly during wound healing and in the growth of connective tissues. It’s also present at high levels in the supportive environment of many tumors, helping cancer cells invade nearby tissues. Because of this, FAP is a focus for developing targeted therapies and diagnostic tools for cancer. Its presence indicates active tissue change, making it a valuable marker for disease progression and a potential target for treatments aimed at disrupting tumor growth.
