Zelltötung

Zelltötung, also known as cell death, is a fundamental biological process that occurs in all multicellular organisms. It is a regulated and essential part of development, tissue homeostasis, and defense against disease. There are two primary forms of cell death: apoptosis and necrosis.

Apoptosis, often referred to as programmed cell death, is a highly controlled and organized process. It involves a cascade of molecular events that lead to the dismantling of the cell in a manner that minimizes damage to surrounding tissues. During apoptosis, the cell shrinks, its DNA is fragmented, and it is engulfed by phagocytic cells. This process is crucial for eliminating damaged or unwanted cells, such as during embryonic development or the removal of senescent cells.

Necrosis, on the other hand, is typically an uncontrolled and accidental form of cell death resulting from injury or disease. Causes of necrosis include trauma, infection, toxins, or lack of oxygen. In necrosis, the cell swells and bursts, releasing its contents into the extracellular space, which can trigger an inflammatory response and potentially damage neighboring cells.

While distinct, both apoptosis and necrosis serve to remove cells from the body. Understanding the mechanisms of Zelltötung is vital for comprehending various physiological and pathological processes, including cancer, neurodegenerative diseases, and autoimmune disorders. Research into these cell death pathways holds significant promise for developing therapeutic strategies for a wide range of medical conditions.
