All-trans retinoic acid increases the number of excitatory synapses in the dorsal hippocampus of mice and improves the ability of neurons to express synaptopodin-dependent synaptic plasticity.
To facilitate human developmental biology research, CRISPR-mediated homologous recombination, tightly inducible gene knockdowns (CRISPRi) and overexpression (CRISPRa) have been efficiently applied to human organoids.
Striatal cholinergic interneurons and astrocytes lose cilia and show dysregulation of Hedgehog signaling in mice with a Parkinson's disease-associated, G2019S LRRK2 mutation or upon loss of PPM1H phosphatase specific for LRRK2-phosphorylated Rab GTPases.
COVID-19 severity, rather than sex or age, predicts SARS-CoV-2 kinetics, and SARS-CoV-2 viral load from lower respiratory tract specimens may predict severe disease days before clinical deterioration for COVID-19 patients.
Genetic and biochemical analyses reveal that two stem-cell-specific microRNAs control stem cell fate decisions between pluripotency and differentiation through repressing Ago2, a key component of the microRNA machinery.

Neuronal circuits can be disrupted by ire-1-dependent mRNA decay to affect germline tumor cell identity by regulating cross-tissue communication in Caenorhabditis elegans.
