An N-terminal CDC42 T43I variant reveals the mechanism of pyrin inflammasome activation.

Heterozygous carboxyl-terminal variants in the RHO guanosine triphosphatase (GTPase) CDC42 are known to cause severe autoinflammatory syndromes. Here, we identified a heterozygous amino-terminal p.T43I (Thr43→Ile) CDC42 variant in patients with autoinflammation and uncovered a molecular link between CDC42 and the infla...

Metformin improves mitophagy-related pathways and mitochondrial-lysosomal homeostasis in chromosome 21 trisomic fibroblasts

The findings support mitophagy inefficiency due to pathway saturation as a key pathogenetic mechanism in trisomic cells and identify metformin as a pharmacological tool capable of relieving the proteostatic overload intrinsic to trisomy 21.
