BOSTON, November 21, 2023 — A newly discovered protein, dubbed Mindin, is showing promise as a potential treatment for depression by directly influencing gut health, researchers at the University of California, San Diego, have found.
Gut Feelings: How a Protein Could Revolutionize Depression Treatment

Scientists have identified a protein that appears to mediate the connection between the gut microbiome and brain function, offering a novel approach to tackling depression.
- Mindin protein regulates the production of serotonin-producing bacteria in the gut.
- Mice lacking Mindin exhibited depressive-like behaviors, which were reversed with fecal transplants from healthy mice.
- The research, published November 20, 2023, in Nature Neuroscience, suggests a direct link between gut health and mental wellbeing.
- This discovery could lead to new therapies targeting the gut microbiome to treat depression.
Could your gut be the key to unlocking better mental health? That’s the question researchers are asking after identifying a protein that seems to act as a crucial intermediary between the bacteria in your digestive system and your brain. This breakthrough offers a fresh perspective on depression, a condition often treated with medications that primarily target brain chemistry.
The Gut-Brain Connection: A Deeper Dive
The study, conducted by a team led by Professor Emily P. Balskus, focused on the role of Mindin in regulating the composition of the gut microbiome. Researchers discovered that Mindin controls the abundance of bacteria responsible for producing serotonin, a neurotransmitter vital for mood regulation. Mice genetically engineered to lack the Mindin protein displayed behaviors indicative of depression, including reduced social interaction and increased anxiety.
“We’ve known for a while that there’s a connection between the gut and the brain, but understanding the molecular mechanisms behind it has been a major challenge,” explained Professor Balskus. “Mindin appears to be a key player in this communication network.”
Restoring Balance: The Potential for New Therapies
The implications of this research are far-reaching. Currently, many antidepressant medications work by increasing serotonin levels in the brain. However, these drugs often come with side effects and don’t work for everyone. Targeting the gut microbiome through therapies designed to boost Mindin production or promote the growth of serotonin-producing bacteria could offer a more natural and effective approach to treating depression.
What Does This Mean for Depression Treatment?
Q: Could gut health be as important as brain chemistry in treating depression?
A: This research strongly suggests that gut health plays a significant, and potentially equal, role in regulating mood and mental wellbeing. Mindin’s influence on serotonin-producing bacteria highlights the direct link between the gut microbiome and brain function.
The researchers emphasize that this is still early-stage research. Further studies are needed to determine whether Mindin plays a similar role in humans and to explore the potential for developing targeted therapies. However, the discovery of Mindin represents a significant step forward in our understanding of depression and opens up exciting new avenues for treatment.
The study was published November 20, 2023, in the journal Nature Neuroscience.
