Formation of cytoplasmic blebs
WebNov 10, 1998 · Cytoplasmic membrane changes associated with apoptosis include the formation of blebs and loss of phosphatidylserine (PS) membrane asymmetry. It was proposed that the blebbing resulted from the cleavage of several important cytoskeletal structure proteins such as fodrin, actin, and Gas2 ( 19, 35, 36) and signaling molecules … WebJun 13, 2024 · Cytoplasmic Blebs in T-Cell Prolymphocytic Leukemia.

Formation of cytoplasmic blebs
Did you know?
Bleb formation can be initiated in two ways: 1) through local rupture of the cortex or 2) through local detachment of the cortex from the plasma membrane. This generates a weak spot through which the cytoplasm flows, leading to the expansion of the bulge of membrane by increasing the surface … See more In cell biology, a bleb is a bulge of the plasma membrane of a cell, characterized by a spherical, "blister-like", bulky morphology. It is characterized by the decoupling of the cytoskeleton from the plasma membrane, … See more Apoptotic function Blebbing is one of the defined features of apoptosis. During apoptosis (programmed cell death), the cell's cytoskeleton breaks up and causes the membrane to bulge outward. These bulges may separate from the cell, taking a … See more • Charras GT, Coughlin M, Mitchison TJ, Mahadevan L (March 2008). "Life and times of a cellular bleb".
