ERK activation waves coordinate mechanical cell competition leading to collective elimination via extrusion of bacterially infected cells.

Epithelial cells respond to infection with the intracellular bacterial pathogen Listeria monocytogenes by altering their mechanics to promote collective infected cell extrusion (CICE) and limit infection spread across cell monolayers. However, the underlying biochemical pathways remain elusive. Here, using in vitro (epithelial monolayers) and in vivo (zebrafish larvae) models of infection with L.

Hemin promotes platelet activation and plasma membrane disintegration regulated by the subtilisin-like proprotein convertase furin.

Platelet activation plays a critical role in thrombosis and hemostasis. Several pathophysiological situations lead to hemolysis, resulting in the liberation of free ferric iron-containing hemin. Hemin has been shown to activate platelets and induce thrombo-inflammation.

From properties to toxicity: Comparing microplastics to other airborne microparticles.

Microplastic (MP) debris is considered as a potentially hazardous material. It is omnipresent in our environment, and evidence that MP is also abundant in the atmosphere is increasing. Consequently, the inhalation of these particles is a significant exposure route to humans.

Phenotypic changes in neutrophil granulocytes after G-CSF administration in patients with acute lymphoblastic leukemia under chemotherapy.

Phenotypic changes in neutrophil granulocytes (NG) after G-CSF have been scarcely studied. Using flow cytometry, we analyzed the changes of CD11b, CD14, CD33, CD71, HLA-DR, CD10, CD16 and CD15 on NG after G-CSF treatment in 6 patients with ALL receiving intensification chemotherapy and in 10 control subjects. After G-CSF we found: expression of HLA-DR, a higher expression of CD11b, CD71 and CD14, a decrease in CD10 positivity, and fluoresence Intesity in CD15 and CD16.
