Sejtkárosodás

Sejtkárosodás, also known as cellular damage or cellular injury, refers to any alteration in the structure or function of a cell that may impair its ability to perform its normal functions. This can occur due to various factors, including physical, chemical, or biological agents. Physical agents such as radiation or extreme temperatures can cause direct damage to cellular components. Chemical agents, including toxins or drugs, can also lead to cellular injury by altering cellular metabolism or disrupting cellular structures. Biological agents, such as viruses or bacteria, can infect cells and cause damage through various mechanisms.

The severity of sejtkárosodás can range from mild to severe, depending on the extent of the damage and the cell's ability to repair itself. Mild damage may result in temporary dysfunction, while severe damage can lead to cell death. The repair mechanisms of the cell, including DNA repair and autophagy, play a crucial role in mitigating the effects of sejtkárosodás. However, if the damage is extensive or the repair mechanisms are overwhelmed, cell death may occur.

Sejtkárosodás can have significant implications for both individual cells and the organism as a whole. In multicellular organisms, the death of cells can lead to tissue damage, inflammation, and potentially organ failure. In single-celled organisms, sejtkárosodás can result in the death of the organism. Understanding the mechanisms of sejtkárosodás and developing strategies to mitigate its effects is essential for maintaining cellular health and preventing disease.
