Likewise, in experimental sepsis in rats HBO2 treatment has shown to stimulate immune‐modulatory activities including IL‐10 modulation resulting in improved survival (Bærnthsen et al., 2017; Buras et al., 2006), but timing and dosage are essential factors for the overall outcome (Bærnthsen et al., 2017; Buras et al., 2006; Lerche et al., 2017). The gene discussed is IL10; the disease is Sepsis.
