Key points from article :
Life span of mice is extended by 20% after treatment every few weeks with serum albumin, beginning in mid-life.
Significant fraction of the issues arising with age are reactions to damaged albumin.
A single protein recombinant mouse serum albumin (rMSA) improved the lifespan and healthspan of mice.
The rMSA used in this study is young and almost undamaged.
Significantly extended lifespan with increased skeletal muscle strength and cognitive ability.
By delivering unmodified serum albumin, the harmful reactions diminish.
Interesting when considered in the context of the beneficial effects from dilution of blood in old animals.
Dilution protocol involves adding albumin, as albumin is one of the few essential items present in the bloodstream.
Further studies will be needed to clarify and replicate these results.
Study by the Tsinghua University published in the journal bioRxiv.
