Cerebrospinal fluid hydroxylase cofactor in schizophrenia.
Cerebrospinal fluid levels of pterin cofactor were measured in off-medication schizophrenic patients and normal control subjects as one aspect of monoamine physiology in schizophrenia. Pterin cofactor is essential for the hydroxylation of several substances including tyrosine, the rate-limiting step in the synthesis of dopamine and norepinephrine. No significant differences were found. Platelet monoamine oxidase activity correlated significantly with pterin levels in male schizophrenic and in female control subjects.
