H2HUBB TAKEAWAY
In this work, a concept of sonocatalytic full water splitting for hydrogen/oxygen immunotherapy of deep tumor is proposed, and a new kind of ZnS nanoparticles with a mesocrystalline structure (mZnS) is developed to achieve highly efficient sonocatalytic full water splitting for sustainable supply of H₂ and O₂ in tumor, achieving a high efficacy of deep tumor therapy. 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?
In this work, a concept of sonocatalytic full water splitting for hydrogen/oxygen immunotherapy of deep tumor is proposed, and a new kind of ZnS nanoparticles with a mesocrystalline structure (mZnS) is developed to achieve highly efficient sonocatalytic full water splitting for sustainable supply of H₂ and O₂ in tumor, achieving a high efficacy of deep tumor therapy. Mechanistically, locally generated hydrogen and oxygen molecules exhibit a tumoricidal effect as well as the co-immunoactivation of deep tumors through inducing the M2-to-M1 repolarization of intratumoral macrophages and the tumor hypoxia relief-mediated activation of CD8+ T cells, respectively.
Why These Findings Matter
These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
How Strong Is This Evidence?
This is laboratory evidence from a in vitro cell-culture laboratory experiment. It is most informative for the biological mechanisms, cellular responses, or biochemical outcomes directly measured.
