EnglishWe investigated 5-HT reuptake and protein kinase of type C (PKC) activation in platelets of 14 OCD patients at baseline and after six months of treatment with different serotonin (5-HT) reuptake inhibitors (SRIs). The results showed that all SRIs provoked a significant increase in both the maximal velocity (V-max) and the Michaelis-Menten constant (K-m) of 5-HT reuptake, as compared with baseline values. The activation of PKC by means of 4-beta-12-tetradecanoylphorbol 13-acetate provoked a significant decrease in V-max values, but the effect was not as evident as at baseline. These findings could indicate that, in OCD patients, SRIs increase the rate of reuptake and decrease the inhibitory effect of PKC and that the two phenomena may be linked, the first perhaps depending upon the second.
