Macrophage extracellular vesicles deliver Mef2d proteins to aggravate Bacteroides fragilis pathogenicity in type 2 diabetes arterial calcification

open access: yesInterdisciplinary Medicine, EarlyView.
Bacteroides fragilis is associated with type 2 diabetes (T2D) arterial calcification and can be activated by macrophage‐derived extracellular vesicles (EVs). BF takes up EVs via receptor‐mediated endocytosis, and activation is induced by EV‐derived Mef2d, thereby inhibiting ArsR family transcriptional regulator transcription.

S100A9 promotes pulmonary arterial hypertension by regulating mitochondria–endoplasmic reticulum interaction‐mediated inflammatory injury of endothelial cells

open access: yesInterdisciplinary Medicine, EarlyView.
Macrophage‐derived S100 calcium‐binding protein A9 (S100A9) promotes the pathological progression of pulmonary arterial hypertension (PAH). S100A9 upregulates the interaction between signal‐transducing adaptor protein 2 and leucine‐rich repeat kinase 2, thereby regulating mitochondria–endoplasmic reticulum (ER) contact.
