Caspar Wistar, M.D.
He was a buddy of Ben Franklin
This is very good news, I believe. My printer seems to agree: when I attempted
to print the article (below) it (my printer) stopped working half way through
the first page, emitted a terrible scream (of joy?) – and quit working. I take that to be a good omen.
You remember CAR T, right?
If not, read
for a refresher course.
In brief, CAR T refers to an immunotheraputic process wherein T cells are
targeted at specific cancer cells, then venture forth through the body to find
them, and kill them. So far CAR T has
only been used on blood cancers, but now an outfit called ITUS Corporation (of
San Jose, California) is preparing to unleash CAR T technology on solid tumors –
beginning with our favorite target – ovarian cancer.
From Bio 1a in high school you remember that cells have
various proteins attached to their external membrane. These proteins have specific functions. For instance, they may signal to glucose
molecules to come hither, attach, and be eaten (cells need nutrition, after
all.) Or they may say “hey, - signals from
the pancreas – come over, lock on, and deliver your instructions. That sort of thing.
Well, some smart people have discovered that a particular
protein – they call it “follicle stimulating hormone receptor” (FSHR) – exists only
on the ovarian cells of adult women. In
principal, these means that one can extract T cells from an OVCA patient,
modify them to recognize (and kill) cells with FSHR proteins on their surfaces –
and destroy those (cancerous) cells. Trials
are underway. Clinical applications:
maybe two years away.
My family used to have a saying that went something like “There’s
many a slip between the cup and the lip”.
That is certainly true, so we must be aware that this discovery – so simple, so promising – may come to nothing.
But I am greatly encouraged.
So what does Caspar Wistar have to do with any of this? I will tell you.
Dr. Caspar Wistar was a physician in Philadelphia and a contemporary
of Benjamin Franklin. He was so
important that various academic units of the University of Pennsylvania have
born his name. The latest incarnation is
the Wistar Institute, which is a biomedical research facility. The CAR T technology as applied to OVCA was
developed in the Wistar labs, using funds provided by you and me through the
NIH. Wistar Institute does biology, not
bio-business, so presumably they sold the right of development to ITUS. However, ITUS has sub-let the actual work to
something called the Moffitt Cancer Center.
No wonder the development efforts will cost upwards of $ I million.
I tell you all this to help you understand how the Pharma
universe operates. I withhold judgement.
My Gmail account tells me I have 127 unread letters. More than likely they all are cancer-related: I get my tips from Google Alerts (ovarian cancer), the NYTimes science section, NIH, NCI, FORCE, etc. – all services that will gladly smother you in information if you give them a chance. I also get tips from individuals: the Ingwalls, Carolyn Joyce, Linda’s sister, and others, from time to time, but these I read immediately. Most of these unread messages undoubtedly are Google Alerts, filled with important information.
ReplyDeleteWell, hell, I am only human. I can’t be expected to stay glued to my computer all the time. I want to watch birds, pet my cat, watch TV some of the time. In fact, I would be watching TV right now, was it not that the Seahawks are getting the stuffing kicked out of them at the moment.
All this is to tell you that I am going to fall even further behind. In a few days I am going to Alaska for Christmas, and then to Borrego Springs in early January. I will re-invigorate the blog parade sometime around mid-January. In the meantime, read some old blogs, drink some beer, and try not to let Donald Trump ruin your life.
