Alzheimer’s disease is a growing
concern in our society. Research has shown that the root of Alzheimer’s disease
may be a protein called tau that is in the brain, but going after this protein
has produced mixed results. The findings
of the report Science Translational
Medicine states that a modified DNA-like structure called antisense oligonucleotides
(ASOs) are designed to recognize and hold together specific RNA molecules
halting them from producing a certain protein. What this means regarding Alzheimer’s
is that ASOs may be able to reduce levels of existing tau and prevent its
formation. This has shown promise in
some diseases such as spinal muscular atrophy and Huntington’s disease. It has
been tested on mice and monkeys. It has shown progress in its subjects so far.
The ASOs prevented cognitive problems in mice of taupathies which include Alzheimer’s,
supranuclear palsy, and corticobasal ganglionic degeneration. Also, decreased
brain inflammation preventing neuronal death and reducing tau aggregates in the
brain. The question now is, Is it safe for human trials? The researchers are
still working on it, and do not yet have a component that is eligible for human
trials. Even though tests were made on mice and monkeys and showed to be
successful, the ASOs are still not safe enough to run on humans.
I
believe in the ASOs. They have shown significant results in the tested subjects
producing lower levels of the tau protein and it lowered the levels of many
neuronal diseases such that, eventually, it will be effective on humans. When
it is effective on humans, we might have a cure, finally, for the awful disease
which is Alzheimer’s. Hopefully one day, when we have a cure, hopefully someday
soon, many lives that are being affected by it may be helped and put at ease
that their loved ones and even themselves are no longer threatened by the brain
deteriorating disease and the sadness that they will eventually forget even
their close friends and family.

Thank you so much for this blog post! I found it extremely interesting. I work in a nursing home and work to take care of Alzheimer's patients daily, but I couldn't ever fully understand how this specific disease affected the brain. I have never done much research on the issue and this was very interesting to read up on and further explore. I had never heard of ASOs before and it was interesting to see its effect on the brains of different organisms. I'm glad that people are putting an importance on understanding Alzheimer's and one day hopefully finding a cure. KT
