“Leah, coffee?” I heard this question at
least daily while I worked in the laboratory of Dr.
Giancarlo Pepeu, Department of Pharmacology at the University
of Florence. Everyday after lunch and
some days at mid-morning, everyone in the lab would
head downstairs to the “bar” to order a
caffé or a macchiato. Don’t be as alarmed
as Carol Bender was when she
came to visit. An Italian bar is nothing like its American
counter part. It is more like an American coffee shop
and it is a veritable staple of Italian culture.
The monumental importance of coffee to the progress of the
Italian day is just one small example of the many cultural
differences between Italy and the U.S. However, I found
many of the stereotypical characteristics of Italians
to be fairly accurate. They do love food and wine, they
do have a great appreciation for beauty, they are indeed
quite fashionable, and they definitely drive more boldly.
As a society that has remained relatively homogeneous
and immune to the influx of outsiders for centuries,
conventional Italian culture has remained fairly intact.
But, things are beginning to change. Italy has recently
seen high levels of immigration from Asia, Africa, and
the nations of the former Yugoslavia. While I was there,
I heard much debate about the many refugees and clandestini
(illegal immigrants) entering the country daily. While
many other nations have been seeing mass immigration
for years, this change has been slow to come to Italy
and the Italians are just beginning to adjust to the
diversification of their country.
Despite their growing pains, the Italians have a remarkably
cosmopolitan outlook. Being a European country, in such
close geographical proximity to other nations, has resulted
in a prevalence of foreign language skills far beyond
American capabilities. Almost everyone I met there was
able to make some conversation in English, while many
spoke it fluently, and others had ability in three or
four different languages. I found the Italians to have
a political awareness that also exceeded my own. One
night at dinner with my host family, the 15-year-old
daughter, Olga, asked me about the process of American
presidential elections. After answering her question
I inquired why she had wanted to know. She replied that
she was studying the U.S. government in her school.
I was rather surprised by this as I barely remember
learning anything about my own government in school,
let alone the governments of other nations.
These were just some of the observations I made about
the current climate in Italy. In my four months there,
I experienced more about life in another part of the
world than I could ever sum up in this article. So,
I’ll move on to the lab. My project involved characterizing
the neuroinflammatory and neurodegenerative processes
in TgCRND8 mice, a transgenic line modeling Alzheimer’s
disease. These mice express a mutant form of the amyloid
precursor protein, which has been found to exhibit an
accumulation of b-amyloid plaques in the brain and spatial
learning deficits. We sought to determine if these mice
also displayed the neuroinflammatory responses and degeneration
of cholinergic neurons seen in Alzheimer’s patients.
As neuroscience research was completely new to me, the
whole project was one big learning experience. I struck
a balance between my old work in human antibodies and
the new by doing immunohistochemical stainings on sections
of the brains of the TgCRND8 mice. I stained for such
things as beta-amyloid plaques, activated astrocytes
and microglial cells, and cholinergic neurons. From
these stainings we found that activated astrocytes and
microglial cells—cells typically invloved in inflammatory
processes—surround the beta-amyloid plaques in
these animals. Furthermore, by counting the number of
neurons that stained positive for choline acetyltransferase,
we determined that there were significantly fewer cholingeric
neurons in the TgCRND8 mice than in controls. This result
implies that these mice do undergo degeneration of the
cholingeric system and it appears to be a new finding.
At the time I left the lab, the group was further characterizing
the inflammatory and neurodegenerative process in these
mice by staining for excitotoxic chemicals and measuring
the level of acetylcholine release in the cortex of
live mice.
Overall, I had an excellent time in Florence. I learned
a great deal not only about Alzheimer’s disease,
the international research community, and Italy, but
about myself as well. Being all alone in a foreign country
tested my adaptability, resourcefulness, and self-confidence
in a way that they never have been before. In this way
I believe that my experience in Italy both shattered
and exceeded my expectations. Although it was much more
trying than I had imagined, it was also much more enriching
than I had hoped for. I would recommend that anyone
with an enthusiasm for science and a sense of adventure
apply to BRAVO!, it will undoubtedly give you more than
you bargain for.
