Sammanfattning : Neutrophils are among the first white blood cells recruited to the site of infection once microbial pathogens enter the host organism. At site, they perform a well-orchestrated chain of processes that aims to kill the microbial invader. Most prominent, neutrophils engulf microbes to inactivate them intracellularly, a process called phagocytosis. LÄS MER
Sammanfattning : The aim of this thesis was to investigate the innate immune response in healthy human airways in vivo after simulation of a Gram-negative infection. Intrabronchial exposure to the TLR4 agonist endotoxin was used as a model for the innate mechanisms in the immune response that are caused by cigarette smoke and by natural infection with Gram-negative bacteria.

3. Pathogenic Neisseria infections of human neutrophils and epithelial cells : focusing on host responses and immune evasion
Sammanfattning : N. meningitidis and N. gonorrhoeae are obligate human pathogens that colonize mucosal surfaces and are often carried asymptomatically. These bacteria have developed adhesive structures that promote adherence to host cells and efficient colonization of new hosts. LÄS MER
Sammanfattning : Inflammation is a localized protective response in vascularized tissues and can be induced by microbial infection or cell and tissue injury. Polymorphonuclear neutrophils (PMN) are the most common white blood cells and are recognized as major cellular mediators of acute inflammation. LÄS MER
Sammanfattning : Neutrophil granulocytes play an important role in the early stages of microbial infection. The neutrophils have to leave the blood stream and migrate out into the tissue where they phagocytose microbes and cell debris from damaged host tissues. LÄS MER
