ALZHEIMER WORM
there he or she is the alzheimer worm
yesterday i got to hold a petri dish full of these
alzheimer worms
i wrote about them recently when i wrote about my composting
worms i had put in my garden
holding that petri dish up to the light and seeing those
little worms that were the size of this .
i will admit that i was in awe
i did get sweaty and my heart rate picked up as i
held that dish
why
what if they held the answer that we have all been looking for
it will be pure science by researchers like those at this
ut lab i visited that will provide the answer or the piece of
the puzzle that is needed for a cure or treatment for
alzhiemers disease
the worms called scientifically c.elegans
are transparent so that you can actually see with a microscope
the neurons that run down their bodies
there are a limited number of them so if one is damaged
you can easily see it
they also have only a limited number of genes i think it was 230+
so when you add a research gene its easily identified on the
worms limited genome
humans have millions of genes
these worms only live 7 days so when a gene for alzheimers is
inserted into their genome its affects will be noticed in 3 days
in humans it will be 20-30 years
in research rats it will be months and sometimes several years
before the genes effect show up
these researchers inserted a alzheimer gene into the worms
genome that produces a protein that accumulates in humans
who have the gene and they develop alzheimers
remember this process occurs over years in humans
but in only 3 days in the alzheimer worm
so its easy to try different treatments to see if those drugs or
chemicals or foods can prevent the protein from forming
thus potentially preventing or slowing down alzheimers
they also have been able to attach fluorescence to these genes so
they will fluoresce hopefully purple since thats the alzheimers
associations color
if this alzheimers protein is produced
then it can be identified simply with the microscope instead of doing
a more lengthy and expensive procedure to identify the protein
in fact hundreds or thousands of chemicals or compounds could
be tested at one time and if there is fluorescence then that can
be measured easily
so drugs or chemicals that are new or old drugs could quickly
be evaluated and within 3 days you will know if they have
potential to work against alzhiemers disease
one drug that was tested was the anticancer drug bexarotene
when it was applied to these alzheimer worms the protein
was not produced and there was no degeneration of
neurons in the worms ie those worms didnt get alzheimers
transfer that to humans
if you gave bexarotene to humans in the early stage or even
earlier than that then they would not develop alzheimers
or develop more alzheimers
hence a cure or treatment for this disease
in fact in 2013 this drug bexarotene which is generically
available now will be tested in a study with humans next year
so we should soon have an answer on this soon
the alzheimer worm research which is not published yet implies
that it may work
from the research lab to the clinical trials
thats how this mystery will be solved
thanks to the research scientists at ut austin for giving me a tour
of their lab
and giving me some hope for the future

Dad - Great blog today. Very interesting report, and glimpse into what these labs are doing for research.
