Sejtvégén

Sejtvégén is a Hungarian term that translates to "cell end" or "cell termination." It most commonly refers to the cessation of a cell's life cycle, a process that can occur through programmed cell death, also known as apoptosis, or through necrosis, which is accidental cell death.

Apoptosis is a highly regulated and essential biological process for multicellular organisms. It allows for the orderly removal of damaged, aged, or unnecessary cells, which is crucial for development, tissue homeostasis, and the prevention of diseases like cancer. During apoptosis, a cell undergoes a series of characteristic morphological and biochemical changes, leading to its dismantling without causing inflammation to surrounding tissues.

Necrosis, on the other hand, is typically a response to external insults such as injury, infection, or lack of oxygen. Unlike apoptosis, necrosis is an uncontrolled process where the cell swells and bursts, releasing its contents into the environment and often triggering an inflammatory response.

The understanding of sejtvégén, particularly apoptosis, is fundamental in various fields of biology and medicine. Research into the mechanisms of programmed cell death has implications for understanding developmental disorders, autoimmune diseases, neurodegenerative conditions, and the efficacy of cancer therapies. Manipulating sejtvégén can be a target for therapeutic interventions aimed at promoting or inhibiting cell death depending on the specific medical context.
