Apoptotic membrane dynamics in health and disease

Abstract: Apoptosis, also known as programmed cell death, is a fundamental homeostatic mechanism essential for normal embryonic development and the maintenance of healthy adult tissues. The processes that affect cell membrane dynamics during the tightly regulated apoptotic program have attracted considerable interest over the years. Distinct biochemical and structural alterations to plasma membrane composition and topography contribute to the efficient removal of cellular corpses. In this review, we will discuss these m… Show more

“…Figure d displays the example of the snapshot SRS images taken every 6 min. Real-time SRS imaging (Movie S3) shows that the cell shrinkage and membrane blebbing (indicated with green arrows) occur immediately after PDT activation, indicating that adherent cells are stressed and undergoing cytoskeletal structure reorganization . On the other hand, numerous bright spots observed in the cytoplasm originate from the LD-UCNP@CS-Rb-TPP with a strong TA signal.…”

“…Morphological changes such as blebs were observed at 0.005 mg mL À1 , indicating cell membranes delaminate from cortical cytoskeletal structures. 56 These blebs became more numerous at 0.05 mg mL À1 , but not at 0.5 mg mL À1 . At 0.5 mg mL À1 , condensation and increased uorescence intensity of the nuclei were observed supporting the cytotoxicity data, indicating that a number of cells were not viable at this concentration.…”

“…Membranes are also highly dynamic systems that act as recruitment focal points for different types of molecular machineries, which perform vital cellular functions such as cell sensing and communication, energy production and conservation, signal transduction and host substrate exchange, to name a few [3]. In addition, this active cell structure is responsible for the lateral organization and compartmentalization of proteins, lipids and their chemically modified counterparts into distinct specialized assemblies that perform many of the fundamental cellular activities required for life and programmed cell death (apoptosis) [20,21] (Fig. 1).…”
