| Outline of Final Research Achievements |
This aimed to evaluate the correlation between SERT uptake ability in human peripheral platelets and SB frequency. Subjects were consecutively recruited from sixth-year students. SB frequency was determined as the summary score of 3-consecutive night assessments using a self-contained EMG detector/analyzer in their home environment. Fasting peripheral venous blood samples were collected in the morning following the final SB assessment. Amount of SERTs and platelets were quantified by ELISA assay. Functional characterization of SERT, 5-HT uptake, maximum velocity (Vmax) and affinity constant (Km) were assessed by [3H] 5-HT uptake assay. The correlation between these aforementioned variables and SB level was evaluated.
A small but significant negative correlation between SB level and [3H] 5-HT uptake was observed (p<0.05, R2=0.063, Spearman correlation). Platelet serotonin uptake is significantly correlated to SB frequency, although it only explains a small amount of SB variability.
