Echinocytes and keratocytes should be considered in the differential diagnosis of spur cell anemia. Echinocytes or burr cells are spiculated red blood cells with uniform, narrow, spikelike surface projections. Spur cells have fewer spicules, and the spicules vary more in size than echinocytes. Keratocytes are acanthocytelike cells with bizarre shapes and horny projections. Differential Diagnoses.
N for natural, K for killer, as its name suggests NK cells are primarily killer cells. With other cells of the innate immune system (neutrophils, monocytes, macrophages, dendritic cells and TÎ³Î´ lymphocytes) they patrol the body and mark cancer or infected cells. for natural, K for killer, as its name suggests NK cells are primarily killer cells.
