| dbo:abstract | Die Rosettierung ist ein zellbiologischer Vorgang, bei dem Erythrozyten kreisförmig um eine zentrale Zelle oder ein Virion angeordnet sind, wodurch unter dem Lichtmikroskop der Eindruck einer Rosette entsteht. (de) Erythrocyte rosetting or E-rosetting is a phenomenon seen through a microscope where red blood cells (erythrocytes) are arranged around a central cell to form a cluster that looks like a flower. The red blood cells surrounding the cell form the petal, while the central cell forms the stigma of the flower shape. This formation occurs due to an immunological reaction between an epitope on the central cell's surface and a receptor or antibody on a red cell. The presence of E-rosetting can be used as a test for T cells although more modern tests such as immunohistochemistry are available. May be caused by Plasmodium in malaria. (en) Il rosetting eritrocitario è quel fenomeno di aggregazione degli eritrociti attorno ad un'altra cellula ematica centrale,a formare una struttura, detta rosetta, che ha la forma di un fiore. Questo fenomeno è particolarmente importante nella malaria causata da Plasmodium falciparum, in quanto l'emazia parassitata dal protozoo funge da cellula centrale, attorno alla quale altri eritrociti si ammassano a formare la rosetta.Il rosetting da Plasmodium falciparum può causare facilmente ischemie, aggravando il decorso clinico della malaria.
