Extremely happy to share our lab’s first paper now published in @NatureSMB! We determined the cryo-EM structures of GluA4, both alone and in complex with TARP2, capturing the receptor in different functional states.
New online: GluA4 AMPA receptor gating mechanisms and modulation by auxiliary proteins
GluA4 AMPA receptor gating mechanisms and modulation by auxiliary proteins
Nature Structural & Molecular Biology, Published online: 15 September 2025; doi:10.1038/s41594-025-01666-7Vega-Gutiérrez et al. present cryo-electron microscopy structures of GluA4-containing AMPA receptors, which are key for brain signaling. They show GluA4-specific conformations and explain how subunit composition shapes receptor architecture, dynamics and function.

Finding correlates of the same signal in different brain areas is not evidence against specialisation, it is evidence for interconnection.
When I flush my toilet, the level in the tank and the flow rate in the supply pipe become perfectly correlated. Yet these toilet areas have distinct functions.

Is neuroscience research really working to understand the human brain? Or do we get lost in mouse cognition? I’ve asked myself this a lot since starting to work with human tissue. Our first Jonas Lab foray into untangling human hippocampal circuits is now online! www.cell.com/cell/fulltex... 1/a few
Human hippocampal CA3 uses specific functional connectivity rules for efficient associative memory
Human hippocampal CA3 networks use sparse and broad synaptic connectivity, and their recurrent synapses employ reliability, precision, and long integration times to enhance memory capacity. Thus, the human hippocampus is distinct from both rodent counterparts and human neocortical circuits.
