An Inducible Luminescent System to Explore Parkinson's Disease-Associated Genes.

With emerging genetic association studies, new genes and pathways are revealed as causative factors in the development of Parkinson's disease (PD). However, many of these PD genes are poorly characterized in terms of their function, subcellular localization, and interaction with other components in cellular pathways. This represents a major obstacle towards a better understanding of the molecular causes of PD, with deeper molecular studies often hindered by a lack of high-quality, validated antibodies for detecting the corresponding proteins of interest.

Aldosterone Contributes to Vasopressin Escape through Changes in Water and Urea Transport.

Hyponatremia (hypo-osmolality) is a disorder of water homeostasis due to abnormal renal diluting capacity. The body limits the degree to which serum sodium concentration falls through a mechanism called "vasopressin escape". Vasopressin escape is a process that prevents the continuous decrease in serum sodium concentration even under conditions of sustained high plasma vasopressin levels.

Emotional change: Neural mechanisms based on semantic pointers.

Emotional change includes generation of new emotions, switching from one emotion to another, and alteration of the frequency and intensity of emotions. Psychotherapists help clients to reduce negative emotions such as sadness and anxiety and increase positive emotions such as happiness and hope. We explain such emotional shifts by the semantic pointer theory of emotions, which views them as brain processes that integrate neural representations of situations, appraisals of the goal-relevance of those situations, and physiological reactions to the situations.

An AMPK activator as a therapeutic option for congenital nephrogenic diabetes insipidus.

Nephrogenic diabetes insipidus (NDI) patients produce large amounts of dilute urine. NDI can be congenital, resulting from mutations in the type-2 vasopressin receptor (V2R), or acquired, resulting from medications such as lithium. There are no effective treatment options for NDI.

Phosphoproteomics identifies microglial Siglec-F inflammatory response during neurodegeneration.

Alzheimer's disease (AD) is characterized by the appearance of amyloid-β plaques, neurofibrillary tangles, and inflammation in brain regions involved in memory. Using mass spectrometry, we have quantified the phosphoproteome of the CK-p25, 5XFAD, and Tau P301S mouse models of neurodegeneration. We identified a shared response involving Siglec-F which was upregulated on a subset of reactive microglia.
