Most infectious diseases have been easily prevented
Sanitation Vaccines Antibiotics Carrier control
Age-related diseases have not. Why not?

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.

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
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)
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
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
