- Genome-wide association studies have discovered hundreds of loci associated with complex brain disorders, but it remains unclear in which cell types these loci are active. Here we integrate genome-wide association study results with single-cell transcriptomic data from the entire mouse nervous system to systematically identify cell types underlying brain complex traits. We show that psychiatric disorders are predominantly associated with projecting excitatory and inhibitory neurons. Neurological diseases were associated with different cell types, which is consistent with other lines of evidence. Notably, Parkinson’s disease was genetically associated not only with cholinergic and monoaminergic neurons (which include dopaminergic neurons) but also with enteric neurons and oligodendrocytes. Using post-mortem brain transcriptomic data, we confirmed alterations in these cells, even at the earliest stages of disease progression. Our study provides an important framework for understanding the cellular basis of complex brain maladies, and reveals an unexpected role of oligodendrocytes in Parkinson’s disease. © 2020, The Author(s), under exclusive licence to Springer Nature America, Inc.

- Purpose Time-related eating patterns have been associated with metabolic and nutritional diseases such as obesity. However, there is a lack of representative studies on this subject. This study's aim was to assess the association between the timing of eating and obesity in a large and representative sample of the Brazilian adult population (POF 2008–2009 survey).Methods Two days of adults’ food diary (n = 21,020) were used to estimate tertiles of first and last meal intake times, eating midpoint, caloric midpoint time, and calories consumed from 18:00 h onwards. BMI was estimated and its values, as well as excess weight (BMI ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2) were used as outcomes. Multiple linear and logistic regressions were performed.Results The first (β = 0.65, 95% CI 0.37–0.93) and last food intake time (β = 0.40, 95% CI 0.14–0.66), eating midpoint (β = 0.61, 95% CI 0.34–0.88) and calories consumed after 21:00 h (β = 0.74, 95% CI 0.32–1.16) and 22:00 h (β = 0.75, 95% CI 0.18–1.32) were positively associated with BMI. The likelihood of having excess weight or obesity was significantly higher in the third tertile of the first food intake time (OR = 1.28, 95% CI 1.13–1.45 and OR = 1.34, 95% CI 1.13–1.58, respectively), last food intake time (OR = 1.16, 95% CI 1.03–1.32; and OR = 1.18, 95% CI 1.00–1.41, respectively), eating midpoint (OR = 1.28, 95% CI 1.13–1.45; and OR = 1.35, 95% CI 1.14–1.59, respectively) and energy consumption after 21:00 h (OR = 1.33, 95% CI 1.10–1.59).Conclusion Chrononutrition meal patterns indicative of late meal intake were significantly associated with high BMI, excess weight and obesity in the Brazilian population.
