With mucus coating the small airways in the lungs, the hair cells are unable to clear out invading bacteria.
Usually, the body's defense system generates a profusion of different antibodies to kill invading bacteria and viruses.
That is the body's primitive first line of defense that recognizes invading bacteria and helps to mount a general attack.
The gene, which exists in slightly different forms in hundreds of plants and animals, produces a protein that attacks invading bacteria.
Neutrophils ingest and kill invading bacteria, releasing cytotoxic, chemotactic and inflammatory mediators at sites of infection.
The overexpression of IL11 was significantly reduced by repeated handling against invading bacteria compared to the control group.
The other hypothesis is that the peptides are surface anti-infective agent similar to AMPs because they inhibit extracellular proteases produced by invading bacteria [21].
Antibacterial agents such as ciprofloxacin incorporated with collagen bi-layer dressings prevent the proliferation of invading bacteria in wounds that are susceptible to infection.
As an immune system defense against invading bacteria, certain cells (e.g., macrophages) will engulf (i.e., phagocytosis) bacteria and destroy them by exposure to lysozymes and ROS.
Among the essential tasks of macrophages is the killing of invading bacteria so any restriction of this ability due to biomaterial implantation must be avoided.
Although autophagy was once considered a bulk degradation event, research shows that autophagy selectively degrades specific proteins, organelles, and invading bacteria, a process termed "selective autophagy".
