Early in his undergraduate research in bioengineering, Sayo Eweje was considering of a profession in medication. He was impressed by the concept of harnessing medical information to enhance sufferers’ lives, having grown up seeing his father achieve this as a gastroenterologist. Nevertheless, his analysis experiences in faculty made him admire how scientific development can result in paradigm-shifting improvements. What if he may contribute to breakthroughs that improved lives on a a lot bigger scale?
“That concept actually captured me, and I spotted that we’re solely enabled to try this by actually delving into the frontiers of science,” he says. In his junior 12 months of faculty, he determined to intention for a profession as a physician-scientist, splitting his time between caring for sufferers and conducting analysis. After graduating, he entered the Harvard-MIT MD/PhD program, which is affiliated with each Harvard Medical Faculty and MIT’s Institute for Medical Engineering and Sciences.
Now, Eweje is getting into his sixth 12 months in this system, and the fourth 12 months of his PhD research in medical engineering by means of the Harvard-MIT Program in Well being Sciences and Expertise. All through his PhD, he has labored within the lab of Elliot Chaikof at Beth Israel Deaconess Medical Heart, the place his analysis has centered on the event of protein-based nanoparticle methods for delivering nucleic acid and protein therapies on to cells contained in the physique.
Eweje’s curiosity on this space was sparked shortly after he entered this system: Preliminary stories describing a promising new gene editing-based remedy for inherited blood issues have been launched, highlighting the healing potential of this method. Nevertheless, administering this remedy entails eradicating blood-forming stem cells from sufferers, enhancing them, then placing them again in. In an effort to accommodate the edited cells, recipients endure heavy chemotherapy, which led to questions surrounding toxicity and scalability.
“The thought that I had, and that many others within the area had, is that if we may ship these gene-editing therapies within the physique with out having to take away cells, with out having to do that chemotherapy, his may very well be a way more efficient and accessible remedy,” Eweje says.
“After desirous about issues like that and understanding that a whole lot of this in the end comes all the way down to drug supply and engineering nanoparticles and supply automobiles, I spotted that’s the place I need to spend my time,” he says. “There are such a lot of challenges in treating illness the place the bottleneck in the end comes all the way down to efficient supply.”
Hanging illness on the supply
Numerous ailments are brought on by mutations in hematopoietic (blood-forming) stem cells, and Eweje selected Chaikof’s lab partly as a result of the staff was searching for methods to ship RNA and protein therapies on to these cells in sufferers. The work has spun off in lots of attention-grabbing instructions since then.
“It began there, but it surely has turn into a wider platform-focused venture,” Eweje explains. “We’re taking a look at issues starting from gene enhancing within the lungs to immunotherapy and desirous about new most cancers therapies.”
This January, he revealed an article in Biomaterials that gave a progress replace on the state of analysis utilizing protein-based nanoparticles to ship nucleic acid therapies to cells. Traditionally, scientists have discovered success with viral vectors for delivering gene-based therapies, however due to these viral origins, there stays the potential for triggering a affected person’s immune system.
“Protein supplies, notably human-derived protein supplies, are far much less prone to set off that immune response, which is one main benefit,” he says. “The opposite factor that we’re actively working in direction of within the lab is this concept of leveraging programmability and exact construction in recombinant proteins.”
Whereas a lot work stays to find out whether or not nonviral, protein-based nanoparticles can used as successfully as these which are virus-derived, or lipid nanoparticles, he’s grateful to have discovered invaluable classes throughout this course of.
“I actually admire the truth that I’ve had a possibility to study what’s on the market, higher perceive the challenges, and carry that information ahead,” he says.
Constructing alternative for others
Exterior the lab and the hospital, Eweje is engaged in training and outreach tasks as shut as Cambridge and so far as Nigeria, the place his household traces their roots. He’s a co-founder of the Program of Ragon and IMES in Science and Drugs (PRISM), which hosts weekly applications for highschool college students within the larger Boston space to study immediately from scientists and clinicians about varied matters in STEM.
“I see youngsters as stem cells,” he says. “They’ve a lot potential to distinguish into so many alternative issues, however you need to put them in a correct atmosphere and provides them the publicity required to know the place they will go.”
He’s additionally a co-managing director of the Vital Healthcare Info Integration Community (CHIIN), a nonprofit that gives medical info to group well being staff in rural and underdeveloped areas of Africa. It operates through a chatbot that may reply to queries over SMS textual content messaging and is subsequently in a position to attain communities with out web entry, not directly helping hundreds of sufferers.
“A part of it was creating confidence within the customers by giving them one thing to have of their again pocket as a reference software,” he says.
As his time within the HST program attracts to an in depth, Eweje goals to defend his PhD subsequent 12 months and return to full-time scientific work at Harvard Medical Faculty. Finally, he envisions a profession on the intersection of scientific medication and biotech innovation.
He additionally intends to proceed encouraging younger folks to discover STEM. “Everybody ought to have the suitable to discover their fullest potential,” he says.
“I discover a whole lot of gratification within the impression that we are able to have on somebody’s life simply by giving them the chance to study one thing, which may change the trajectory of what they do,” he provides. “We now have not solely the pleasure of doing that, but additionally a bit of little bit of an obligation.”
