There were 5 positive IQ1 site patients (CFS(+)) whose serum autoantibody was higher than the cut-off value shown as a dashed line. In normal controls, there were no subjects with positive autoantibody against the mAChR. As shown in Table 1, fatigue scores, expressed by visual analogue scale, were similar between CFS(+) and CFS(2) patients (5.961.2 vs. 6.761.4, respectively). In all the neuropsychological assessments, there were no significant differences among the 3 groups (Table 2). Representative maps of the BPND of [11C](+)3-MPB using the Logan plot with reference regions are presented in Figure 1B. The BPND of [11C](+)3-MPB in each brain of CFS(+) patients were significantly lower than those in CFS(2) patients and control subjects (Fig. 1B, Table 3). Compared with controls, a 10?5 reduction of BPND was observed in CFS(+) patients (Table 3). AChE MedChemExpress ML-264 activity did not differ among the 3 groups (Table 3). There were no significant differences in BPND between CFS(2) patients and control subjects. There were no regions in which the BPND of [11C](+)3-MPB significantly correlated with any neuropsychological indices.DiscussionReduction of [11C](+)3-MPB binding was observed in CFS(+) patients who showed a higher level of serum autoantibody against the mAChR, compared with CFS(2) patients and normal controls. In contrast, the AChE activity was similar in subjects from the 3 groups. The indices of intelligence and cognitive function did not differ among the 3 groups, and these indices did not relate to [11C](+)3-MPB binding in this study. To our knowledge, this is the first PET study to demonstrate a reduction of neurotransmitter receptor binding in brains of CFS patients with high levels of serum autoantibody. The present results suggest the possibility of the autoantibody interacting directly with the mAChR in the brain, although the autoantibody at this level did not affect cognitive function in CFS patients. The present finding supports the idea that penetration of the antibody into the brain resulted in impaired BBB function. This may be one possible mechanism by which the serum autoantibody could affect central mAChR function [57]. Although the precise mechanism of the production of the autoantibodies against the mAChR in the CFS brain is unclear, there are the following mechanisms based on an autoimmune reaction theory: 1) a viral infection of the brain tissue exposes the brain to self-antigen; and 2) an infection (not nece.Psychological tests.Test Japanese version of the National Adult Reading Test Advanced Trail-Making Test A Advanced Trail-Making Test B Advanced Trail-Making Test C Rey Complex Figure: immediate recall Rey Complex Figure: delayed recall Wisconsin Card Sorting Test Wechsler Memory Scale-Revised General memory Delayed memory Verbal memory Visual memory AttentionControl 72.0611.1 124.3628.7 163.2634.6 263.9645.0 28.762.5 28.063.3 327.56108.CFS(2) 79.3613.7 125.1619.2 161.5631.2 260.8645.8 29.862.7 28.763.1 314.7641.CFS(+) 75.469.3 125.5630.7 187.4670.1 275.7627.0 28.763.3 27.862.7 338.26106.112.168.0 113.869.0 109.769.1 114.065.5 102.0614.114.569.4 115.0611.2 112.0610.6 114.765.2 100.5616.109.265.3 112.466.5 107.067.0 113.266.3 103.8613.Data are expressed as mean 6 SD.
