H2HUBB TAKEAWAY
In a laboratory model, the bulk-RNA sequencing combined with single-cell RNA sequencing revealed that hydrogen treatment effectively reduced the excessive aggregation and infiltration of innate immune cells. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.

What Effects Did Molecular Hydrogen Have?
Despite hydrogen being a prospective molecule for anti-inflammatory effects, the on-demand delivery of hydrogen that could synchronize with the dynamic inflammation stages has yet remained unaddressed. The bulk-RNA sequencing combined with single-cell RNA sequencing revealed that hydrogen treatment effectively reduced the excessive aggregation and infiltration of innate immune cells. Specifically, hydrogen reduced the proportion of Ptgs2+Nos2+ pro-inflammatory macrophages (PIMs) by mitigating mitochondrial stress and suppressing HIF-1α-induced glycolysis, the immune-metabolic regulation of which reduced harmful crosstalk between PIMs and hypodermal fibroblasts and facilitated extracellular matrix production accompanied by the ultimate wound repair.
