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.

ESCRT-0 regulates AMPA receptor currents and Ca2+- dependent signaling

Mahsa Pourhamzeh, Lara E. Dozier, Amanda Wilpitz, Yixing Du, Daniel B. McClatchy, Mariel Kristine B Micael, Joshua E. Mayfield, Stephen K. Gilmore-Hall, Josephina E Ronson, Katrin Soldau, Donald P. Pizzo, Brent D. Aulston, Erin E. Sullivan, Timothy F. Shay, Jin Wang, , Christina J. Sigurdson

This study shows that Hrs, an ESCRT-0 protein, modulates AMPA receptor currents and Ca2+-dependent signaling by sensing and responding to neuronal activity at synapses.

PrPC-induced signaling in human neurons activates phospholipase Cγ1 and an Arc/Arg3.1 response

Daniel Ojeda-Juárez, Gail Funk, Emily Richards, Alexander J. Rajic, Daniel B. McClatchy, Katrin Soldau, Xu Chen, John R. Yates, Steven L. Gonias, Christina J. Sigurdson

The paper shows that PrPC ligands in human neurons trigger PLCγ1 signaling and an Arc/Arg3.1 response, indicating neuronal hyperactivity in prion disease.
