The Claim

In aged mdx mice with advanced Duchenne muscular dystrophy, serum creatine kinase levels remain elevated following BLS-M22 treatment, with a statistically significant reduction observed at 8 weeks but not at 12 weeks, indicating transient or incomplete attenuation of muscle damage.

Description
1 study reviewed
In plain English

In aged mice with a severe form of muscular dystrophy, a treatment called BLS-M22 reduces a marker of muscle damage at 8 weeks but not at 12 weeks, meaning the protective effect does not last.

See the scientific wording

In aged mdx mice with advanced Duchenne muscular dystrophy, serum creatine kinase levels remain elevated despite BLS-M22 treatment, with a statistically significant reduction only at 8 weeks but not at 12 weeks, suggesting transient or incomplete protection against muscle damage.

Why this might work

The immune system makes antibodies that block a protein called myostatin, which normally limits muscle growth. Blocking myostatin temporarily reduces muscle tearing and enzyme leakage into the blood, but it does not fix the underlying weakness in the muscle membrane, so damage returns over time.

    The probiotic treatment helped reduce a muscle damage marker in mice after 8 weeks, but we don’t know if it still worked at 12 weeks — and since the muscles didn’t get stronger or less scarred, it probably didn’t fix the problem long-term.
