Disease-Associated Dopamine Receptor D2 Variants Exhibit Functional Consequences Depending on Different Heterotrimeric G-Protein Subunit Combinations by Nele Niebrügge, Olga Trovato, Roman Praschberger, Andreas Lieb

“…We were able to confirm the reported gain-of-function phenotype by Rodriguez-Contreras et al. and extend it by the use of the most abundant heterotrimeric G-protein subunits, Gα_oA and Gα_i1, β₁ and β₂, and γ₃ and γ₇, in mouse and human basal ganglia. <b>Conclusions:</b> Although our results indicate that the interaction of the two variants with the most highly expressed heterotrimeric G-protein complex subunit combinations also results in a gain-of-function phenotype, they also clearly demonstrate that the phenotype can be significantly altered, dependent on heterotrimeric G-protein complex expression.…”

Corticospinal Tract Wiring and Brain Lesion Characteristics in Unilateral Cerebral Palsy: Determinants of Upper Limb Motor and Sensory Function by Cristina Simon-Martinez, Ellen Jaspers, Lisa Mailleux, Els Ortibus, Katrijn Klingels, Nicole Wenderoth, Hilde Feys

“…However, multiple regression analyses showed that motor function was predicted by the CST wiring (more preserved in individuals with contralateral CST (p<0.01)), lesion extent, and damage to the basal ganglia and thalamus. Sensory function was predicted by the combination of a large and later lesion and an ipsilateral or bilateral CST wiring, which led to increased sensory deficits (p<0.05). …”

Associations between CAG repeat size, brain and spinal cord volume loss, and motor symptoms in spinocerebellar ataxia type 3: a cohort study by Zhi-Xian Ye, Xuan-Yu Chen, Meng-Cheng Li, Xin-Yuan Chen, Yu-Sen Qiu, Ru-Ying Yuan, Zhi-Li Chen, Min-Ting Lin, Jian-Ping Hu, Ying Fu, Wan-Jin Chen, Ning Wang, Shi-Rui Gan, on behalf of the OSCCAR Investigators

“…SCA3 patients evolved along a stage-independent decline that began in the cerebellum, progressed to spinal cord, brainstem, thalami, and basal ganglia, and extensive subcortex. Expanded CAG repeat size was associated with right cerebellar lobule IV volume (r = − 0.423, P < 0.001) and cervical spinal cord area (r = − 0.405, P < 0.001), and higher ICARS (r = 0.416, P < 0.001). …”

“…The visualization zones of the pathological process in the brain in case of toxic damage are mainly basal ganglia and/or thalamus and dentate nucleus, cortical zone of grey matter, periventricular zone of white matter, corticospinal tract and corpus callosum; asymmetric white matter damage as a sign of demyelination; parietal-occipital subcortical vasogenic edema and lesions of the central pons are characteristic. …”
