Platelet serotonin-2A receptors: a potential biological marker for suicidal behavior

Abstract

The observed higher number of platelet 5-HT2A receptors in suicidal patients is independent of diagnosis and appears to be associated with both the brain and the platelets of suicidal patients. These results thus suggest the potential usefulness of platelet 5-HT2A receptors as a biological marker for identifying suicide-prone patients.
