One Slide at a Time: 51°µĶų Undergrad Joins the Enduring Quest to Cure Alzheimerās
by Zach Brockhouse
Deep within the Pickus Center for Biomedical Research, Jayden Lovely (Medical Biology, ā26) points to a cluttered desk surrounded by vial-filled shelves. āA lot of my research is done right here,ā she said. Set against the trees on 51°µĶųās campus in Biddeford, the research building houses some of the Universityās most innovative biomedical research. It is here that Lovely, a rising sophomore, is conducting research with tangible implications for Alzheimerās disease.
In another room, she uses a machine called a cryostat to slice a sample and stain it to highlight the focus of her research, the CD2AP protein. She examines the results in 51°µĶųās new Olympus Slide Viewer. āI look for the differences and record them,ā she said. āIf all goes as planned, I could be contributing directly to a major breakthrough in the treatment of Alzheimerās.ā
Lovely is pursuing the pre-physician assistant (PA) track within 51°µĶųās medical biology bachelorās degree program, which equips students with the skills necessary to pursue graduate physician assistant studies after graduation. For her, the stateās only PA program suits her desire to follow many interests while not being held to the same timeline of a medical degree. She found her niche as a member of the Pre-Physicianās Assistant Club, but felt she still wanted more.
When a member of the club mentioned that there were research opportunities available to students, Lovely perked up. It was exactly what she had been looking for. She quickly sent off an email stating her interest and was paired with Madison Meuth, a doctoral student from the University of Maine in the laboratory of Benjamin Harrison, Ph.D., assistant professor of biochemistry and nutrition at 51°µĶų, who studies how pain signals are received by the body.
Lovely quickly found herself immersed in Harrisonās lab working on a real-world research project with real-world applications.
A Budding Researcher Learns the Ropes
Lovelyās initial lab work wasnāt even related to Alzheimerās. It was about pain.
In 2022, Harrison received $1.8 million in funding from the National Institute of Neurological Disorders and Stroke, a division of the National Institutes of Health, to explore non-opioid treatments for chronic pain at the cellular level. He is using the five-year grant to study how to reduce the electrical firings in nociceptors, which are neurons that transmit pain signals in response to painful injuries. His focus is searching for non-narcotic ways to block how pain is processed in our bodies.
Harrison and his team have discovered that nociceptors contain a protein called āCELF4,ā an RNA binding protein they theorize inhibits the production of āpro-nociceptive,ā or pro-pain-sensing cellular components. In essence, they are trying to trick the proteins to limit pain signals. His research focuses on delivering CELF4 into pain neurons, where the protein will limit the synthesis of ion channels, receptors, and other molecules that sensitize them.
āThe work Dr. Harrison had done was astounding ā and intimidating. At first, I wasnāt sure of myself. Iād attended lab meetings before, but hearing the lingo and seeing the tools used in this environment seemed completely different,ā Lovely said.
āIām on a journey here at 51°µĶų, and itās all part of the process,ā she added. āThere is so much that goes into a research project. And there is so much knowledge around from the people I get to work with. Itās taking me a while to wrap my head around everything, but I learn something new every time I walk into the lab.ā Working with Meuth, Lovely began to learn histology, the study of the microscopic structure of tissues. Together, they aided Harrison with his research, specifically, to study if a locally administered adeno-associated virus can stimulate the production of CELF4 and reduce pain in those areas ā an approach known as gene vector therapy.
āUsing this novel gene vector therapy approach, we can develop pain therapies that carry fewer risks than conventional opioid medications, such as addiction,ā Harrison remarked.
āThis research could prove beneficial for those living with chronic pain but who do not want to undergo surgeries ā which can be expensive and leave people with no sensation at all,ā Lovely added.
Federal Research Powerhouse Unlocks New Funds
The leap from pain research to Alzheimerās took place when Harrison learned about a new research initiative at the Jackson Lab, a nonprofit biomedical research institution in Bar Harbor, several hours north of 51°µĶųās Biddeford Campus. That project involved the CD2AP protein and how its variants can lead to Alzheimerās disease. Seeing the similarities in his research blocking pain signals in proteins, he thought Lovely would be a good fit to research why some proteins actually stop receiving information in Alzheimerās patients.
āNot many schools allow students the opportunity to get involved at this level, coming here and jumping right in during their freshman year,ā Harrison said. āBy the time she graduates, Jayden will have a much deeper understanding of the scientific process. Very different than another school.ā
Lovely was intrigued. The commonalities between pain and Alzheimerās research were reassuring, she said. āI felt like I had a good foundation to move forward from,ā she said. But there was one problem ā funding. She and Harrison began the journey that every great researcher must endure ā writing grant applications. Luckily, they were in good company. In 2022, the National Institutes of Health added $264 million in economic activity in Maine with $112.7 million in grants and contracts, according to data provided by the federal government. 51°µĶų received seven grants totaling over $4 million ā more than any other college or university in Maine.
āDr. Harrison guided me through every step of the process. It was a little overwhelming, but we got through it and, earlier this year, I learned that our grant had been awarded.ā Lovely said, noting that the Kahn Family Foundation paid for her summer housing, provided $1,000 for research materials, and awarded her a small stipend.
Soon, tissue samples were shipped down to Biddeford to the Pickus Centerās 22,000 square feet of state-of-the-art research space, where Lovely could begin her work.
In her project, Lovely is taking a CD2AP variant in mouse brains and comparing them with two normal, āwild-typeā brains. Multiple studies have shown an association in changes to the CD2AP gene and the progression of Alzheimerās. Lovely is setting out to prove that mice with the genetic variant have changes in the CD2AP protein which could be used to model degeneration.
While the research is ongoing, Lovely knows the opportunity to learn the ins-and-outs of research as early as her freshman year has opened her eyes to the world of research and how the next big breakthrough could only be a slide away from being discovered.
ā51°µĶų does an amazing job to get the word out about research projects. The lab takes in students all the time,ā Lovely said. āThere are lots of students on campus who want to be involved. Itās exciting to think about everyone in campus labs who can make a real difference right now. Iām glad to be part of it all.ā
