Acute infection is known to induce rapid expansion of hematopoietic stem cells (HSCs), but the mechanisms supporting this expansion remain incomplete. Using mouse models, we show that inducible CD36 is required for free fatty acid uptake by HSCs during acute infection, allowing the metabolic transition from glycolysis towards β-oxidation. Mechanistically, high CD36 levels promote FFA …

Prognostic value of #D-dimer for adverse outcomes in patients with infective #endocarditis: an observational study
Increased D-dimer levels have been shown to correlate with adverse outcomes in various clinical conditions. However, few studies with a large sample size have been performed thus far to evaluate the prognostic value of D-dimer in patients with infective endocarditis (IE). Methods613 patients with IE were included in the study and categorized into two groups …
Mitigating the threat of emerging #infectious diseases; a coevolutionary perspective
“Nothing in biology makes sense except in the light of evolution”[1] and this is no less true for viral pathogens than it is for their host species. To appreciate the full extent of the challenges posed by current and future emerging infectious diseases (EIDs), I believe it is insightful to take a coevolutionary perspective. Coevolution …
