Understanding Cell Death
Cell death is a fundamental process that occurs throughout the life cycle of an organism. It plays a crucial role in maintaining tissue homeostasis by eliminating damaged, infected, or unwanted cells. There are several different types of cell death, each with its own unique molecular mechanisms and functional consequences.
Apoptosis
Apoptosis is a highly regulated and programmed form of cell death essential for normal development, tissue homeostasis, and immune system function. It involves a cascade of intracellular signaling events culminating in the activation of caspases, a family of proteases that cleave key cellular substrates leading to the characteristic morphological changes associated with apoptosis. These changes include cell shrinkage, chromatin condensation, and DNA fragmentation.
Parthanatos
Parthanatos is a caspase-independent form of cell death mediated by poly(ADP-ribose) polymerase (PARP) activation. It involves the translocation of apoptosis-inducing factor (AIF) from mitochondria to the nucleus, where it induces chromatin condensation and DNA fragmentation. Unlike apoptosis, parthanatos is often associated with conditions such as stroke and neurodegenerative diseases.
Ferroptosis
Ferroptosis is an iron-dependent form of regulated cell death caused by the accumulation of lipid peroxides. It is characterized by the inhibition of glutathione peroxidase 4 (GPX4) and the consequent accumulation of lipid peroxides, leading to oxidative damage and cell death. Ferroptosis plays a role in various diseases, including cancer and neurodegeneration.
Necroptosis
Necroptosis is a form of programmed necrosis that occurs when apoptotic pathways are blocked or inhibited. It is characterized by the activation of receptor-interacting protein kinase 3 (RIPK3) and mixed lineage kinase domain-like protein (MLKL), resulting in plasma membrane rupture and release of intracellular contents. This form of cell death is implicated in inflammatory diseases and viral infections.
Cuproptosis
Cuproptosis is a form of cell death triggered by copper ions. It is characterized by the release of copper ions from intracellular compartments, leading to oxidative stress, mitochondrial dysfunction, and cell death. The regulation of copper levels and the understanding of cuproptosis are important for diseases related to copper metabolism.
Pyroptosis
Pyroptosis is a highly inflammatory form of cell death initiated by the activation of inflammasomes, a group of cytosolic protein complexes that sense pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs). It involves the activation of distinct caspases and the release of pro-inflammatory cytokines, such as IL-1β and IL-18. Pyroptosis is crucial in the immune response to infections and inflammatory diseases.
Erebosis
Erebosis is a recently described form of regulated cell death found in the Drosophila intestine and named after the Greek word έρεβος, meaning “deep darkness”. While its mechanisms and implications are still being explored, it adds to the growing complexity of our understanding of cell death processes.
