SOD1 and infection: Infections occur when foreign invaders multiply within the body, not only inducing damage to cells and tissues through bacterial toxin secreted by bacteria, but also triggering the immune response.[1a] Nanozymes could also take effect to reduce the inflammatory response and thus promote wound healing, such as superoxide (SOD)‐ and catalase (CAT)‐mimicking ones.[9] Thereinto, SOD‐mimicking nanozymes could reduce inflammation through eliminating O2•− from the wound and CAT‐mimicking ones could promote other enzyme activity or reduce inflammation by catalyzing H2O2 to produce O2.
