H2HUBB TAKEAWAY
The researchers found that oral intake of hydrogen-rich water abolishes an immediate-type allergic reaction in mice. The authors concluded that the authors' studies also suggest that hydrogen is a gaseous signaling molecule like nitric oxide. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.
What the Findings Mean
H2HUBB reviewed how hydrogen-rich water was evaluated in this publication and summarizes the source-grounded findings below. The researchers found that oral intake of hydrogen-rich water abolishes an immediate-type allergic reaction in mice.
What the Researchers Studied
The study used a in vitro cell-culture laboratory experiment.
What Effects Did Molecular Hydrogen Have?
The researchers found that oral intake of hydrogen-rich water abolishes an immediate-type allergic reaction in mice. Using rat RBL-2H3 mast cells, the researchers demonstrated that hydrogen attenuates phosphorylation of the FcepsilonRI-associated Lyn and its downstream signal transduction, which subsequently inhibits the NADPH oxidase activity and reduces the generation of hydrogen peroxide. The authors concluded that the authors' studies also suggest that hydrogen is a gaseous signaling molecule like nitric oxide.
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?
