immunfelügyelet

Immunfelügyelet, a German term, translates to immune surveillance in English. It refers to the process by which the immune system recognizes and eliminates cells that are abnormal or potentially harmful to the body. This surveillance is crucial for preventing the development of diseases, most notably cancer.

The immune system continuously monitors the body for foreign invaders, such as bacteria and viruses, as well as for endogenous threats like precancerous or cancerous cells. Cells that exhibit altered surface proteins or other molecular changes indicative of damage or mutation are flagged as targets for destruction. This recognition is primarily mediated by immune cells like T cells and natural killer (NK) cells, which identify these aberrant cells and initiate a response to eliminate them.

A breakdown in immunfelügyelet can have significant consequences. If the immune system fails to detect or eliminate cancerous cells effectively, these cells can proliferate and form tumors. Similarly, a compromised immune surveillance system can lead to an increased susceptibility to infections. Research into immunfelügyelet is a cornerstone of immunology and cancer research, aiming to understand how to enhance these natural defense mechanisms to combat disease.
