The Douglas-Bell Canada Brain Bank: A goldmine for research on brain diseases

Humans have actually constantly been amazed by the brain.

clinical understanding about this 1.3 kg of delicate compound embedded in our cranium has actually long been insufficient, stunning technical advancements made in the last few years are now introducing a Golden Age of molecular neuroscience.

These advancements have actually been enabled partially thanks to brain banks, which maintain human brains in the very best possible conditions for clinical research studyHere in Montréal, we have among the world’s biggest such banks, the Douglas-Bell Canada Brain Bank (DBCBB), established in 1980 at the Douglas Hospital

The DBCBB, which gets a number of brains every month, has actually gathered over 3,600 specimens to date. Every year, its group procedures lots of tissue demands from researchers in Québec, Canada and abroad, preparing some 2,000 samples for research study.

Over the previous 40 years, these efforts have actually resulted in a significant variety of discoveries about various neurological and psychiatric illness.

As a complete teacher in the department of psychiatry at McGill University, scientist at the Douglas Research Center and director of the DBCBB because 2007, I operate in close partnership with Dr. Gustavo Turecki, co-director of the DBCBB and accountable for the element dedicated to psychiatric health problems and suicide.

A quick history of research study on the human brain

Researchers just started to recognize the tiny components that comprise the human brain in the 2nd half of the 19th century.

That was when brains were protected for the very first time in formalin, an option that protects biological tissue so that it can be dealt with more quickly and kept over a longer term.

At the very same time, accuracy instruments and procedures were being established that made it possible to analyze the tiny attributes of anxious tissue.

Till the middle of the 20th century, scientists were primarily pleased with protecting the brains of clients, taken throughout autopsies, so they might utilize them to determine possible macroscopic or tiny modifications connected to either neurological or psychiatric signs.

This remains in reality what the German neurologist Alois Alzheimer did when he evaluated the brain of among his clients struggling with dementia. In 1906, he explained, for the very first time, the tiny sores which identify the illness that now bears his name.

Up until completion of the 1970s, many collections of brain specimens maintained in formalin were integrated in healthcare facility environments, a bit like the cabinets of interests of olden days.

Towards completion of the 20th century, brand-new speculative methods were established permitting the high-resolution analysis of cells and particles within biological tissues.

It then ended up being essential to gather and protect human brains, gotten with the approval of the specific or his/her household, in conditions suitable with contemporary clinical methods.

Scientists started freezing among the cerebral hemispheres in order to determine its numerous molecular elements. The other hemisphere was protected in formalin to be utilized for macroscopic and tiny physiological research studies.

This was the context in which the Douglas-Bell Canada Brain Bank was developed.

New speculative methods are yielding outcomes

Leading scientists from lots of universities all over the world now utilize DBCBB samples to advance their research study. This, naturally, consists of a variety of groups in Québec.

With his group from the Douglas Research Center, which is associated with McGill University, Judes Poirier found that the APOE4 gene is a danger element for Alzheimer’s illnessMore just recently, the group of Gilbert Bernier, teacher in the department of neuroscience at Université de Montréal, found that the sores quality of this illness are related to irregular expression of the BMI1 gene

With regard to psychiatric diseases, and more particularly anxiety, significant development has actually been made just recently by the McGill Group for Suicide Studies

Utilizing advanced techniques to separate and evaluate human brain cells, Turecki’s group has actually prospered in exactly recognizing the cell types whose function is impacted in males who have actually experienced significant anxietyand after that finding that the cell types associated with this health problem vary in between males and females

These speculative methods create substantial information sets that can be analyzed in subsequent research studies. This holds true, for instance, of work performed in my lab, which determined indications of consistent modifications in neuroplasticity within the prefrontal cortex of individuals with a history of kid abuseThe research studies pointed out above allowed us to find at least one of the cell types included in this phenomenon.

Simply put, the speculative approaches we have today permit us to break the brain down into its primary parts in order to comprehend its functions and dysfunctions.

Recognize, avoid, screen and deal with

Thanks to the effort and commitment of the whole DBCBB group, along with the never-failing assistance of all its partners, clients (frequently confidential) and financing bodies– especially the FRQS research study fund and Québec’s suicide research study network, the Réseau québécois sur le suicide, les difficulties de l’humeur et les problems associés— this vital resource has not just handled to make it through, however to grow and turn into one of the biggest brain banks worldwide.

There is every factor to think that, in the years to come, the DBCBB will play a crucial function in the progressively accurate recognition of the biological reasons for brain illness, and, as an outcome, will add to the recognition of brand-new targets for much better methods to avoidance, screening and treatment.
