Autoimmunity and the Clearance of Dead Cells
To maintain organismal homeostasis, phagocytes engulf dead cells, which are recognized as dead by virtue of a characteristic "eat me" signal exposed on their surface. The dead cells are then transferred to lysosomes, where their cellular components are degraded for reuse. Inefficient engulfment of dead cells activates the immune system, causing disease such as systemic lupus erythematosus, and ...
متن کاملMRI reveals slow clearance of dead cell transplants in mouse forelimb muscles
A small molecule tetraazacyclododecane-1,4,7,10-tetraacetic acid (Gd‑DOTA)4‑TPP agent is used to label human mesenchymal stem cells (hMSCs) via electroporation (EP). The present study assessed the cytotoxicity of cell labeling, in addition to its effect on cell differentiation potential. There were no significant adverse effects on cell viability or differentiation induced by either EP or cellu...
متن کاملMitochondria help dynamins get a grip
T he dynamin-like GTPases spur mitochondria to break up. Two papers (1, 2) reveal new details about the molecular platforms that position these mitochondria-splitting proteins on the organelles. In yeast, the dynamin-like GTPase Dnm1 dismembers mitochondria by settling on the outer surface of the mitochondrial membrane and polymerizing into spirals that cleave the organelle (3). Two other prote...
متن کاملMitochondria in cell death.
Apoptosis can be thought of as a signalling cascade that results in the death of the cell. Properly executed apoptosis is critically important for both development and homoeostasis of most animals. Accordingly, defects in apoptosis can contribute to the development of autoimmune disorders, neurological diseases and cancer. Broadly speaking, there are two main pathways by which a cell can engage...
متن کاملLoss of the plant DEAD-box protein ISE1 leads to defective mitochondria and increased cell-to-cell transport via plasmodesmata.
Plants have intercellular channels, plasmodesmata (PD), that span the cell wall to enable cell-to-cell transport of micro- and macromolecules. We identified an Arabidopsis thaliana embryo lethal mutant increased size exclusion limit 1 (ise1) that results in increased PD-mediated transport of fluorescent tracers. The ise1 mutants have a higher frequency of branched and twinned PD than wild-type ...
