Bovine PMN responses to extracellular vesicles released by tachyzoites and -infected host cells.

Bovine besnoitiosis is a re-emerging cattle disease caused by the apicomplexan parasite , which severely affects individual animal welfare and profitability in cattle industry. We recently showed that tachyzoite exposure to bovine polymorphonuclear neutrophils (PMN) effectively triggers neutrophil extracellular trap (NET) formation, leading to parasite immobilization hampering host cell infection. So far, the triggers of this defense mechanism remain unclear.

Development and evaluation of an F-labeled nanobody to target SARS-CoV-2's spike protein.

COVID-19, caused by the SARS-CoV-2 virus, has become a global pandemic that is still present after more than two years. COVID-19 is mainly known as a respiratory disease that can cause long-term consequences referred to as long COVID. Molecular imaging of SARS-CoV-2 in COVID-19 patients would be a powerful tool for studying the pathological mechanisms and viral load in different organs, providing insights into the disease and the origin of long-term consequences and assessing the effectiveness of potential COVID-19 treatments.
