Source-BioMed-Central A recent study spearheaded by a collaborative effort known as PsychENCODE has shed new light on the genetic underpinnings of neuropsychiatric diseases neuropsychiatric diseases such as schizophrenia and Alzheimer’s disease. The findings, published in Science on May 23, mark a significant milestone in understanding the complex relationship between genetic variation and susceptibility to these debilitating conditions. Revealing Genetic Variation in Brain Cells Led by Mark Gerstein, the Albert L. Williams Professor of Biomedical Informatics at Yale School of Medicine, the study delved into the intricate genetic landscape of brain cells. Over 2.8 million cells from the brains of 388 individuals, including those with  neuropsychiatric disorders  and healthy counterparts, underwent rigorous single-cell experiments. The researchers identified 28 distinct cell types and scrutinized gene expression and regulation within these cells. Unraveling Mechanisms of Disea...

Source-psypost Hidden Complexity in Astrocytes Revealed A recent study published in Nature has shed light on the unexpected complexity within astrocytes and their involvement in repetitive behaviors associated with various neuropsychiatric diseases . Led by Prof. Zhang Xiaoming from the Shanghai Institute of Immunity and Infection (SIII) of the Chinese Academy of Sciences, along with Profs. Gao Qiang, Fan Jia, and Yang Li from Fudan University, the research highlights the potential of astrocytes as therapeutic targets for such conditions. Astrocytes, dominant glial cells within the  central nervous system  (CNS), are known for their diverse functions in metabolic support, neuroprotection, and homeostasis. However, their specific roles within neural circuits and contributions to neurological diseases have remained unclear. The study focused on astrocytes within the central striatum, revealing a unique population expressing the Crym gene, which encodes the protein µ-crystallin. ...
