The role of peptides in the central nervous system function.

The role of peptides such as fibrinogen degradation products (FDP), albumin degradation products (ADP), globulin degradation products (GDP), Bradykinin (BRS) and Angiotensin II (A) in CNS function is presented. Peptides change the activity of the CNS, of the centrally acting drugs and of some neuromediators. The mechanism of the phenomena observed is discussed.
