Creative Minds: Taking Aim at Adverse Drug Reactions

Sherrie Divito
As a practicing dermatologist, Sherrie Divito sees lots of patients each week at Brigham and Women’s Hospital, Boston. She also sees lots of research opportunities. One that grabbed her attention is graft-versus-host disease (GvHD), which can arise after a bone-marrow transplant for leukemia, lymphoma, or various other diseases. What happens is immune cells in the donated marrow recognize a transplant patient’s body as “foreign” and launch an attack. Skin is often attacked first, producing a severe rash that is a harbinger of complications to come in other parts of the body.
But Divito saw something else: it’s virtually impossible to distinguish between an acute GvHD-caused rash and a severe skin reaction to drugs, from amoxicillin to carbamazepine. In her GvHD studies, Divito had been researching a recently identified class of immune cell called tissue-resident memory T (Trm) cells. They remain in skin rather than circulating in the bloodstream. The clinical similarities made Divito wonder whether Trm cells may also help to drive severe skin allergies to drugs.
Divito has received a 2016 NIH Director’s Early Independence Award to find out. If correct, Divito will help not only to improve the lives of thousands of people with GvHD, but potentially benefit the millions of other folks who experience adverse reactions to drug.
Creative Minds: Building a CRISPR Gene Drive Against Malaria

Researchers have used Drosophila melanogaster, the common fruit fly that sometimes hovers around kitchens, to make seminal discoveries involving genetics, the nervous system, and behavior, just to name a few. Could a new life-saving approach to prevent malaria be next? Valentino Gantz, a researcher at the University of California, San Diego, is on a path to answer that question.
Gantz has received a 2016 NIH Director’s Early Independence Award to use Drosophila to hone a new bioengineered tool that acts as a so-called “gene drive,” which spreads a new genetically encoded trait through a population much faster than would otherwise be possible. The lessons learned while working with flies will ultimately be applied to developing a more foolproof system for use in mosquitoes with the hope of stopping the transmission of malaria and potentially other serious mosquito-borne diseases.
Creative Minds: Studying the Human Genome in 3D

As a kid, Jesse Dixon often listened to his parents at the dinner table discussing how to run experiments and their own research laboratories. His father Jack is an internationally renowned biochemist and the former vice president and chief scientific officer of the Howard Hughes Medical Institute. His mother Claudia Kent Dixon, now retired, did groundbreaking work in the study of lipid molecules that serve as the building blocks of cell membranes.
So, when Jesse Dixon set out to pursue a career, he followed in his parents’ footsteps and chose science. But Dixon, a researcher at the Salk Institute, La Jolla, CA, has charted a different research path by studying genomics, with a focus on understanding chromosomal structure. Dixon has now received a 2016 NIH Director’s Early Independence Award to study the three-dimensional organization of the genome, and how changes in its structure might contribute to diseases such as cancer or even to physical differences among people.
Creative Minds: Interrogating a Master of Disguise

When I volunteered several years ago as a physician in a small hospital in West Africa, one of the most frustrating and frightening diseases I saw was sleeping sickness. Now, an investigator supported by the NIH Common Fund aims to figure out how this disease pathogen manages to evade the human immune system.
Monica Mugnier’s fascination with parasites started in college when she picked up the book Parasite Rex, a riveting, firsthand account of how “sneaky” parasites can be. The next year, while studying abroad in England, Mugnier met a researcher who had studied one of the most devious of parasites—a protozoan, spread by blood-sucking tsetse flies, that causes sleeping sickness in humans and livestock across sub-Saharan Africa.
