However, there are still unmet needs in this area.
According to Dr. Michael Brenner, rheumatologist and immunology researcher at Brigham and Women’s Hospital at Harvard Medical School, most patients only experience a partial benefit from available medications, and about a third may achieve full remission. Some patients don’t respond to any current treatments, highlighting the ongoing challenge of finding more effective therapies.
Dr. Brenner and his team, supported by a Foundation Innovative Research Award, are focused on finding new treatments for these patients by investigating inflammatoryInflammation is a normal part of the body’s defense to injury or infection, and, in this way, it is beneficial.

To conduct their research, they collected inflamed tissue from patients and analyzed individual cells.
“What is [the individual cell] doing, and what’s causing it to behave abnormally? That molecular information, which we refer as the genomic level, allows us to understand how we might block that abnormal activity and restore the cell to a more normal state,” explains Dr. Brenner.
By identifying abnormalities in these inflamed cells, researchers can collaborate with pharmaceutical and biotech companies to make drugs that target and block the abnormal pathways, thereby reducing inflammationInflammation is a normal part of the body’s defense to injury or infection, and, in this way, it is beneficial.

“This was previously unknown—we discovered it with Foundation funding over the past two or three years,” says Brenner.
Looking ahead, Dr. Brenner to the future, Brenner says AI technology is going to be increasingly used in helping researchers develop new treatments.
“There have been significant advances in biology, technology, and computational science. These fields are converging, dramatically accelerating our understanding of disease mechanisms and the identification of drug targets, particularly in inflammatoryInflammation is a normal part of the body’s defense to injury or infection, and, in this way, it is beneficial.
