Physical activity prevents acute inflammation in a gout model by downregulation of TLR2 on circulating neutrophils as well as inhibition of serum CXCL1 and is associated with decreased pain and inflammation in gout patients.

Objectives: Gout is the most prevalent inflammatory arthritis. To study the effects of regular physical activity and exercise intensity on inflammation and clinical outcome, we examined inflammatory pathogenesis in an acute model of murine gout and analyzed human gout patient clinical data as a function of physical activity.

Methods: NF-κB-luciferase reporter mice were organized into four groups and exercised at 0 m/min (non-exercise), 8 m/min (low-intensity), 11 m/min (moderate-intensity), and 15 m/min (high-intensity) for two weeks.

Circulating Gasdermin-D in Critically Ill Patients.

Unlabelled: The key to further improving outcomes in sepsis lies in understanding and abrogating the dysfunctional immune response that leads to organ failure. Activation of gasdermin-D, a pore-forming protein within the inflammasome cascade, has recently been recognized as the critical step in pyroptosis and organ dysfunction. In this study, we sought to investigate the presence of gasdermin-D in critically ill subjects.

Inactivation of CFTR by CRISPR/Cas9 alters transcriptional regulation of inflammatory pathways and other networks.

Background: Individuals with cystic fibrosis (CF) experience elevated inflammation in multiple organs, but whether this reflects an inherent feature of CF cells or is a consequence of a pro-inflammatory environment is not clear.

Method: Using CRISPR/Cas9-mediated mutagenesis of CFTR, 17 subclonal cell lines were generated from Caco-2 cells. Clonal lines with functional CFTR (CFTR) were compared to those without (CFTR) to directly address the role of CFTR in inflammatory gene regulation.
