A well-functioning immune system is required to operate host defense mechanisms against tumors.
Constitutive epithelial host defense mechanisms are defined as those functions mediated by intact airway epithelium at baseline, homeostatic conditions [Figure 3]a.
A deep understanding of host defense mechanisms is thus crucial for developing innovative therapies.
The normal physiologic response to localized infection includes activation of host defense mechanisms that result in the influx of activated neutrophils and monocytes, release of inflammatory mediators, local vasodilation, increased endothelial permeability (in part though the zonulin pathway), and activation of coagulation pathway.
Thus, AhR has pathway-specific roles that modulate host defense mechanisms during infection at least when AhR is tested in model high affinity ligands.
Pseudomonas aeruginosa has become an important cause of infection, especially in patients with compromised host defense mechanisms. It has an ability to rapidly develop resistance to multiple classes of antibiotics.
However, some pathogens have also the capacity to overcome neutrophil-mediated host defense mechanisms and establish infections leading to disease.
Dvorak and colleagues (18) concluded more than 35 years ago that host defense mechanisms are not impaired in patients with HS.
Dvorak and colleagues's concluded more than 35 years ago that host defense mechanisms are not impaired in patients with HS.
Innate host defense mechanisms of fish against viruses and bacteria.
FGI-101-1A6 targets and eliminates only the infected cells through induction of normal host defense mechanisms.
Biofilms are known for their high level of antimicrobie resistance and resilience to host defense mechanisms. Little is known of the immune response to biofilm infections; however, mucosal surfaces have a defense mechanism that inhibits initial attachment of bacteria to a surface.(6) Prompt killing of these bacteria may account for the resistance of mucosal surfaces to biofilm formation.
