Data-driven discovery of cell-type-directed network-correcting combination therapy for Alzheimer's disease.

Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder characterized by heterogeneous molecular changes across diverse cell types, posing significant challenges for treatment development. To address this, we introduced a cell-type-specific, multi-target drug discovery strategy grounded in human data and real-world evidence. This approach integrates single-cell transcriptomics, drug perturbation databases, and clinical records.

The GluA1 cytoplasmic tail regulates intracellular AMPA receptor trafficking and synaptic transmission onto dentate gyrus GABAergic interneurons, gating response to novelty.

The GluA1 subunit, encoded by the putative schizophrenia-associated gene GRIA1, is required for activity-regulated AMPA receptor (AMPAR) trafficking, and plays a key role in cognitive and affective function. The cytoplasmic, carboxy-terminal domain (CTD) is the most divergent region across AMPAR subunits. The GluA1 CTD has received considerable attention for its role during long-term potentiation (LTP) at CA1 pyramidal neuron synapses.

A Black Feminist Study of Black Mother-Daughter Sexual Communication.

There is a well-established body of literature on parent-child sexual communication (PCSC) among Black families. Still, most of this work focuses on reducing sexual risk behaviors among Black girls and focuses less on the multidimensionality of PCSC among Black parents and their daughters. In this qualitative study, we explored Black mother-daughter PCSC by analyzing interviews with 29 Black mothers in the U.

CHCHD2 mutant mice display mitochondrial protein accumulation and disrupted energy metabolism.

Mutations in the mitochondrial cristae protein CHCHD2 lead to a late-onset autosomal dominant form of Parkinson's disease (PD) which closely resembles idiopathic PD, providing the opportunity to gain new insights into the mechanisms of mitochondrial dysfunction contributing to PD. To begin to address this, we used CRISPR genome-editing to generate CHCHD2 T61I point mutant mice. CHCHD2 T61I mice had normal viability, and had only subtle motor deficits with no signs of premature dopaminergic (DA) neuron degeneration.

Sex-specific role for the long noncoding RNA Pnky in mouse behavior.

The aberrant expression of specific long noncoding RNAs (lncRNAs) has been associated with cognitive and psychiatric disorders. Although a growing number of lncRNAs are now known to regulate neural cell development and function, relatively few lncRNAs have been shown to underlie animal behavior. Pnky is an evolutionarily conserved, neural lncRNA that regulates brain development.
