Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.Extracellular vesicles from severe COVID‐19 airways carry depleted miRNAs and elevated DAMPs, reprogramming monocytes toward senescence, impaired metabolism, and predominantly reduced cytokine responses. However, they drive excess IL‐8 production, amplifying neutrophil recruitment and dysfunctional inflammation across the respiratory tract.

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.ABSTRACT Extracellular vesicles (EVs) are central mediators of tumour‐stroma communication, yet the mechanisms governing their biogenesis and functional cargo remain poorly understood. Here, we identify CD133 (Prominin‐1), selectively expressed in basal‐like triple‐negative breast cancer (BL‐TNBC) cells, acts as a key organizer of EV production and ...
