IFNL1 and susceptibility to pneumonia measurement: Given the strong induction of proteins that are regulatory or can act in regulatory manners (IL-10, IL-29, IL-6, IL-1Ra), the negative correlation of severe trauma with the ability to fight off infections like pneumonia, and post-acute sequelae of both infections and trauma, these data support future studies on the networked role of responses to pathogens and traumatic injury.
