Reduced phosphatases and hyperphosphorylated glutamatergic receptors persist from early to late stages of prion disease

Alexander J. Rajic, Daniel Ojeda-Juárez, Dipannita Sarkar, Paige Sumowski, Samantha Flores, Mahsa Pourhamzeh, Katrin Soldau, Donald P. Pizzo, Christina J. Sigurdson

This study shows that phosphatase reduction and receptor hyperphosphorylation occur early in prion disease and precede inflammation.

A synapse-specific refractory period for plasticity at individual dendritic spines

J. Casado Flores, Dipannita Sarkar, Karen Zito

The paper investigates a synapse-specific refractory period for plasticity at dendritic spines, showing it is linked to reduced CaMKII signaling and can be overcome by increasing PSD95 levels.
