Institut de Biochimie, Université de Lausanne, Epalinges, Switzerland.

Neutrophils are critical immune cells that protect our body against invading pathogens. They generate antibacterial DNA structures called neutrophil extracellular traps (NET). Recently we identified a new mechanism that enables NET formation. Read More

The leukocyte nucleus must be sufficiently elastic to squeeze through tissue barriers during migration, but not so collapsible as to risk damaging chromatin. The proper balance is struck in part by the composition of the nuclear lamina, a flexible meshwork composed mainly of intermediate filaments woven from type A and type B lamin proteins, that is located subjacent to the inner nuclear membrane. There is now increasing evidence that, in addition to influencing nuclear shape and stiffness and cell migration, lamins and lamin-interacting proteins may also interact functionally with chromatin to influence leukocyte gene expression, differentiation, and effector function, including T cell differentiation, B cell somatic hypermutation, and the formation of neutrophil extracellular traps (NETosis).

Neutrophils are the most abundant type of leukocytes with diverse functions in immune defense including production of reactive oxygen species, bacteriocidal proteins, neutrophil extracellular traps, and pro-inflammatory mediators. However, aberrant accumulation of neutrophils in host tissues and excessive release of bacteriocidal compounds can lead to unexpected injury to host organs. Neutrophil-mediated liver injury has been reported in various types of liver diseases including liver ischemia/reperfusion injury, nonalcoholic fatty liver disease, endotoxin-induced liver injury, alcoholic liver disease, and drug-induced liver injury.

Background: Inflammation is emerging as an essential trigger for thrombosis. In the interplay between innate immunity and coagulation cascade, neutrophils and neutrophil extracellular traps (NETs) can promote thrombus formation and stabilization. In ischemic stroke, it is uncertain whether the involvement of the inflammatory component may differ in thrombi of diverse etiology. Read More

Mooren's ulcer (MU) is a refractory autoimmune corneal ulcer with a high recurrence rate. So far, its molecular profiles and pathomechanisms remain largely unknown. Therefore, we aim to characterize the protein profiles of MU specimens by data-independent-acquisition (DIA) mass spectrometry (MS), and to define the functions of differentially-expressed proteins (DEPs).
