Ex vivo study on the relationship between the circadian clock of blood neutrophils and the effects of alpha1-antitrypsin therapy (ERS 2024) - "Blood was incubated alone or with 2 mg/ml AAT (Respreeza) and/or 5 µg/ml lipopolysaccharide (LPS) from Escherichia coli for 30 min...Overall, our data show that short exposure of the blood to exogenous AAT has an impact on the neutrophil phenotype and that this effect is related to the neutrophil circadian clock. The circadian clock of myeloid cells may influence the efficiency of augmentation therapy and needs further analysis."
