| PDGFRB is a true druggable receptor tyrosine kinase with relevance to tumor stroma, angiogenesis, pericytes, fibrosis, BBB integrity, and AD vascular dysfunction.
| Field |
Suggested Entry |
| Target |
PDGFRB / PDGFR-β |
| Full Name |
Platelet-derived growth factor receptor beta |
| Target Class |
Receptor tyrosine kinase |
| Main Ligands |
PDGF-BB, PDGF-DD |
| Primary Biology |
Pericyte recruitment, vascular maturation, fibroblast activation, stromal remodeling, cell migration, proliferation, BBB maintenance |
| Cancer Relevance |
High: tumor stroma, angiogenesis, pericytes, CAFs, invasion, metastasis, therapy resistance |
| AD Relevance |
Medium-high: brain pericytes, blood-brain barrier integrity, neurovascular dysfunction, soluble PDGFRβ as a pericyte injury marker |
| Therapeutic Direction |
Context-dependent. In cancer, inhibition or stromal normalization may be useful. In AD, preservation/restoration of PDGFRβ signaling is likely protective. |
