  4. 4. Aging is: The life-long accumulation of “damage” to the body that occurs as an intrinsic side- effect of the body’s normal operation. The body can tolerate some damage, but too much of it causes disease and disability.

  14. 14.  Total synthesis of glucosepane, allowing identification of antibodies and degraders (Science, 2015)  Modified bacterial enzyme protects cells from atherogenic oxysterols (Biotech Bioeng, 2012)  Catalytic antibodies cleave cardiotoxic amyloid (J Biol Chem, 2014)  Much more ongoing in our research centre and funded labs
