The Role of Neutrophils and Neutrophil Elastase in Pneumococcal Pneumonia [PDF]
Streptococcus pneumoniae, also known as pneumococcus, is a Gram-positive diplococcus and a major human pathogen. This bacterium is a leading cause of bacterial pneumonia, otitis media, meningitis, and septicemia, and is a major cause of morbidity and mortality worldwide. To date, studies onS.

Objectives: Chronic neutrophilic leukemia (CNL) is a rare, but distinct, entity within myeloproliferative neoplasms, characterized by splenomegaly, sustained mature neutrophilia, and absence of the Philadelphia chromosome. In 2013, oncogenic mutations in

Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]
Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

Neutrophils are short-lived effector cells of the innate immune system that form the first line of defense against microbial pathogens.1 Recent studies show that, by migrating to bone marrow, these cells can also induce (VACV)-specific T cell responses.2 Neutrophils polarize to distinct phenotypes in response to environmental cytokine/chemokine signals.

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Novel anti-tumour necrosis factor receptor-1 (TNFR1) domain antibody prevents pulmonary inflammation in experimental acute lung injury. [PDF]
BACKGROUND: Tumour necrosis factor alpha (TNF-α) is a pleiotropic cytokine with both injurious and protective functions, which are thought to diverge at the level of its two cell surface receptors, TNFR1 and TNFR2.

Neutrophils are abundant in the circulation and are one of the immune system's first lines of defense against infection. There has been substantial work carried out investigating the role of neutrophils in malaria and it is clear that during infection neutrophils are activated and are capable of clearing malaria parasites by a number of mechanisms ...

More than a century ago, in 1881, Bizzozero1 discovered platelets and their role in primary hemostasis. Since this founding study, it has been shown that, in addition to the scaffold of platelets and fibrin, other proteins and cells play an important role in thrombus formation and stabilization.

Airway monocyte modulation relates to tumour necrosis factor dysregulation in neutrophilic asthma
Background Dysregulation of tumour necrosis factor-α (TNF-α) signalling is implicated in neutrophilic asthma. TNF-α signalling involves membrane-bound and soluble ligand (TNF-α) and receptors (TNFRs); however, little is known about how these proteins are
