My idea right from the beginning, I guess, was to dismantle the immune system one gene at a time so we could track the mutations that cause problems.

If we think of the immune system as a machine, then we are far from even knowing all of its parts.

Autoimmunity is probably the next frontier. The majority of cases of autoimmune disease result from a complex genetic problem that has environmental influences. It is a colossal task for the immune system to maintain tolerance to self and yet be ready to react to everything in the world around us.

Love backtracks to a beginning where seekers track, only to a time, where my beginning is an everlasting Love.

A mutation can create an alternative form of a phenomenon - a phenotype or trait - and we can learn a lot by seeing this alternative state. Once I saw a mouse with no eyelids. It simply had a membrane over the eyes. I found it fascinating that there is a single gene required for eyelids to develop.

You fought the good fight. You were in it right up to the beginning.
