Limitations of fluorescent timer protein maturation kinetics to isolate transcriptionally synchronized cortically differentiating human pluripotent stem cells

Posted by klaurent August 31, 2023September 7, 2023UCSF

Kavli Affiliate: Seth Shipman | Authors: Manuel Peter, Seth Shipman and Jeffrey D Macklis | Summary: Differentiation of human pluripotent stem cells (hPSC) into distinct neuronal populations holds substantial potential for disease modeling in vitro, toward both elucidation of pathobiological mechanisms and screening of potential therapeutic agents. For successful differentiation of hPSCs into subtype-specific neurons […]

CaMKII autophosphorylation but not downstream kinase activity is required for synaptic memory

Posted by klaurent August 31, 2023September 7, 2023UCSF

Kavli Affiliate: Roger Nicoll | Authors: XIUMIN CHEN, Qixu Cai, jing zhou, Samuel J Pleasure, Howard Schulman, Mingjie Zhang and Roger A Nicoll | Summary: CaMKII plays a critical role in long-term potentiation (LTP), a well-established model for learning and memory through the enhancement of synaptic transmission. Biochemical studies indicate that CaMKII catalyzes a phosphotransferase […]
