- 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.

- 12. Cell loss, cell atrophy Division-obsessed cells Death-resistant cells Mitochondrial mutations Intracellular junk Extracellular junk Extracellular matrix stiffening No new type of damage confirmed since 1982 And, I’ve said so without challenge since 2002 Damage type
- 13. Why? That was easy How? That’s where we have a new plan What? That’s where we show you it’s a good plan (can be done, is being done)
- 14. Cell loss, cell atrophy Division-obsessed cells Death-resistant cells Mitochondrial mutations Intracellular junk Extracellular junk Extracellular matrix stiffening Cell therapy, mainly Telomerase/ALT gene deletion plus periodic stem cell reseeding Suicide genes, immune stimulation Allotopic expression of 13 proteins Transgenic microbial hydrolases Phagocytosis by immune stimulation AGE-breaking molecules/enzymes Damage type The maintenance approach
- 15. 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
