Finally out in Nature genetics! Our results reveal a novel role for the Alzheimer genetic risk factor PLCG2. Its neuronal Downregulation (or very rare Loss-of-function variants) seem to promote increased Aβ secretion, Tau hyperphosphorylation, and synaptic dysfunction www.nature.com/articles/s41...

PLCG2 downregulation impairs synaptic function and increases Alzheimer’s disease hallmarks in neuronal cultures - Nature Genetics
This study demonstrates that downregulation of PLCG2, primarily in neurons, impairs synaptic function and elevates amyloid-β levels and Tau protein phosphorylation.

In this preprint, the main consortia working on Alzheimer GWAS combined their efforts to validate an detect new loci associated with AD risk. We observed 91 genome-wide significant signals (16 nove) . Among these 91 loci, 56 of them are specifically detected in clinically diagnosed AD cases.

In this preprint led by Devrim Kilinc and Pierre Dourlen, we observed that differential expression of BIN1 isoforms in the presynaptic part leads to differential synaptotoxicity. BIN1 isoforms could contribute to the synaptic loss observed in Alzheimer's disease. www.biorxiv.org/content/10.1...

In this preprint, primarily conducted by Dolores Siedlecki, we established a neuron-microglia co-culture model within the synaptic chamber of a microfluidic device. This compartmented approach enables us to study synapse phagocytosis in close proximity to microglia. www.biorxiv.org/content/10.1...
