a chemical conjugate of human/rat CRF to the ribosome-inactivating protein, saporin
targets cells expressing corticotropin-releasing factor receptor 1 (CRF1 receptor)
Corticotropin-releasing hormone/factor (CRH/CRF) is the principal neuropeptide involved in regulating the stress response. It stimulates ACTH release from the pituitary gland. When centrally administered to animals it produces somatic changes analogous to those seen in both depression and anxiety. In humans, it is capable of reproducing the hormonal changes which are characteristically seen in depressed patients. CRF-SAP eliminates cells expressing the CRF1 receptor making it an effective tool to determine their neurobiological role(s). CRF-SAP is not suitable for retrograde transport.
Elimination of Specific Cell Type
- Cells expressing the corticotropin-releasing factor (hormone) receptor 1 (CRF1 receptor) are eliminated with this reagent.
- All other cells are left untouched.
- Not suitable for retrograde transport.
Effective Tool to Study Disease States
- Elimination of CRF receptor-positive cells is useful to determine their neurobiological role(s).
