What is the role of neutrophils in the case of a lower urinary tract infection?

Neutrophils play a crucial role in combating bacterial infections, including those occurring in the lower urinary tract. When there is an infection, such as a urinary tract infection (UTI), neutrophils are among the first responders that mobilize to the site of infection. They are a type of white blood cell that performs several key functions to help eliminate pathogens.

One of the primary mechanisms through which neutrophils protect the body is by phagocytosing bacteria, meaning they engulf and digest these harmful microorganisms. Additionally, neutrophils can release enzymes and reactive oxygen species that are toxic to bacteria, effectively killing them and helping to control the infection.

In the context of a lower urinary tract infection, neutrophils are integral to the immune response. Their presence in the urine can often be detected through urine tests, indicating an ongoing immune reaction to the bacterial presence. This direct combat against the infection is essential for resolving the UTI and preventing further complications.
