Cytoskeletal dynamics of human erythrocyte
WebJan 19, 2024 · The cytoskeleton of the red blood cell, a two dimensional sheet like structure with dynamic linkages, plays a major role in its deformability. The interdependent relationship between the cytoskeleton and RBC deformability under various conditions such as metabolism, hematologic and systemic disorders and senescence is reviewed. 1 … WebDefects in the cytoskeleton produce changes in erythrocyte deformability and stability, affecting cell viability and rheological properties. Such abnormalities are seen in different pathologies of special interest, such as different types of anemia, hypertension, and diabetes, among others.
