How Caffeine May Prevent Spinal MS in Humans

Spinal multiple sclerosis—also called myelitis—is among the most debilitating forms of multiple sclerosis (MS), attacking the spinal cord and disrupting nerve signals from the brain. For patients and doctors alike, stopping it before it starts remains a major goal. Recent findings suggest a surprising candidate may help: your morning coffee.

Lab tests show mice given the human equivalent of six to eight cups of coffee daily were far less likely to develop a lab-induced autoimmune condition similar to spinal MS. That dose of caffeine appears to block immune cells from entering the central nervous system, where they cause damage.

What Is Experimental Autoimmune Encephalomyelitis (EAE)?

EAE is the animal model used to study human spinal multiple sclerosis. Like MS in people, EAE is an autoimmune disorder where the immune system mistakenly attacks the body’s own tissues—in this case, the brain and spinal cord nerves. This leads to inflammation and nerve damage along the spinal pathways.

How Caffeine Affects the Immune Response

Researchers at Cornell University, led by Jeffrey Mills, found that giving mice a daily dose of caffeine equivalent to six to eight human cups reduced their risk of developing EAE. The mechanism? Caffeine binds to adenosine receptors. Adenosine is a molecule normally present throughout the body that helps regulate energy transfer and sleep—but in MS, it also plays a key role in allowing immune cells to cross into the central nervous system.

By occupying those adenosine receptors, caffeine effectively blocks adenosine’s usual function, thereby preventing immune cells from infiltrating and attacking spinal nerves. This interference is likely what protects the mice from EAE under high caffeine intake.

The Role of CD73 Enzyme and Adenosine Receptors

Additional experiments showed that mice lacking either adenosine receptors or the CD73 enzyme—which is needed to produce adenosine outside of cells—also had a significantly lower chance of developing EAE. These genetic factors support the theory that interrupting adenosine signaling can prevent the autoimmune attack central to MS and EAE. Caffeine’s ability to bind these same receptors reinforces its potential preventive role.

Current Treatments for Spinal MS in Humans

Doctors typically divide MS treatment into acute and maintenance phases. In acute spinal MS attacks, common treatments include corticosteroids such as methylprednisolone, dexamethasone, and prednisone, as well as intravenous immunoglobulin and B vitamins (mainly B1 and B12). For those with conditions like diabetes or ulcers, alternatives such as immunosuppressants (e.g., azathioprine or cyclophosphamide) may be used. To prevent relapse during remission, interferon is often prescribed. In stubborn or recurrent cases, autologous stem cell transplantation is an option.

Stem cells are early, undifferentiated cells capable of developing into various functional cell types and tissues. Known for their “plasticity” and self-renewal, they are sometimes called “source cells” or “universal cells.” Stem cell therapy for spinal MS dates back to the 1950s, primarily using hematopoietic stem cells, and was named one of the top ten most promising medical breakthroughs in 2005.

Frequently Asked Questions

How much caffeine did the mice consume in the study?

The mice received the equivalent of six to eight cups of coffee per day for a human. This dosage was enough to reduce their likelihood of developing EAE, the mouse model for spinal MS.

What is EAE and how does it relate to human spinal MS?

EAE, or experimental autoimmune encephalomyelitis, is an autoimmune disease in mice that mimics human spinal MS. Both involve the immune system attacking the central nervous system, especially the spinal cord and brain nerves.

How does caffeine prevent immune cells from attacking the spinal cord?

Caffeine blocks adenosine from binding to its receptors. Since adenosine normally allows immune cells to enter the central nervous system, caffeine’s presence stops that process, protecting the spinal nerves from autoimmune damage.

What role does the CD73 enzyme play in MS development?

CD73 is an enzyme required to produce adenosine outside of cells. Mice without CD73 had a lower risk of EAE, suggesting that cutting off adenosine production or reception can reduce autoimmune attacks linked to spinal MS.

What treatments exist for spinal MS in humans today?

Treatments include corticosteroids like methylprednisolone during acute attacks, immunosuppressants for those with other conditions, interferon for maintenance, and stem cell transplants for severe or recurring cases. Stem cell therapy has been explored since the 1950s and was highlighted as a promising breakthrough in 2005.
