For years, the cause of lupus was a big mystery. It left millions of people dealing with a hard-to-predict autoimmune disease. But, in July 2023, new research brought light to this complex issue.cause of lupus foundUnderstanding the Main Cause of Bursitis and Prevention
Stanford researchers made a big discovery. They found a link between lupus and the Epstein-Barr virus. This virus is found in about 95% of Americans. This pivotal finding gives hope to patients everywhere, changing how we treat lupus.
Scientists at Northwestern Medicine and Brigham and Women’s Hospital have found the cause of lupus. This groundbreaking research was published in July 2023. It shows that an imbalance of T cells is the main cause of systemic lupus erythematosus (SLE), the most common type of lupus.
Bill Robinson, a professor at Stanford Medical School, says this discovery is a big deal. It shows how Epstein-Barr virus (EBV) leads to lupus. The team’s findings are important for finding new treatments.
A team of skilled researchers made this discovery. They came from top institutions. Led by experts in immunology and rheumatology, they used advanced methods to find lupus’s cause.

This breakthrough is a big win for patients. It means new ways to treat lupus. By knowing the disease’s cause, doctors can create better treatments.
Patients now have hope for better care. This discovery also shows how vital research into autoimmune diseases is.
Lupus is a complex autoimmune disorder that affects millions worldwide. It makes the immune system attack healthy tissues by mistake. This condition has many symptoms, making it hard to diagnose and treat.
About 1.5 million Americans have lupus, with almost 90% being women. Symptoms can vary but often include hair loss, joint pain, and unusual rashes.
There are several types of lupus, each with its own symptoms. The most common is Systemic Lupus Erythematosus (SLE). It can affect many organs and systems in the body.

The immune system plays a key role in lupus. It mistakenly sees the body’s own tissues as foreign and attacks them. This autoimmune response causes inflammation and damage to different parts of the body.
“The imbalance of T cells is a significant factor in the development of lupus, as it disrupts the normal functioning of the immune system.”
— Medical Expert, Immunologist
Understanding how the immune system affects lupus is vital. It helps in finding treatments that target the disease’s root cause, not just its symptoms.
The July 2023 lupus triggers article shared new insights into lupus. It was thanks to careful research. We’ll look into how scientists found this key discovery, showing the complex nature of lupus.
The study’s design was key to finding lupus’s cause. Researchers picked patients with lupus and compared them to healthy people. This comparative analysis showed differences in T cell populations.
They used a special sequencing technology to look at T cell subsets. This helped them find that lupus patients have an imbalance of T cells. There are too many harmful T cells and not enough healing ones.
The study used the latest lab techniques. Stanford researchers used targeted sequencing technology to remove infected white blood cells. This let them study T cell populations closely, gaining important insights.
By mixing advanced lab methods with a solid study design, the team found what causes lupus. This finding is a big step towards new treatments and ways to manage the disease.
Recent studies have found that lupus is often caused by an imbalance of T cells. This discovery is key to understanding and treating the disease. The theory says that the right balance of T cells is essential for a healthy immune system.
T cells are vital for fighting infections and healing. But in lupus, this balance is lost. There’s too much of a T cell that harms healthy cells and not enough that repairs them.
T cells are important white blood cells in our immune system. They come in two types: those that cause damage and those that heal. In lupus, the wrong type of T cell is too common.
Research shows lupus patients have too many damaging T cells. These cells attack healthy tissues. They also have too few healing T cells, which are needed to reduce inflammation and repair tissues.
The T cell imbalance leads to lupus symptoms by letting damaging T cells take over. This causes inflammation and damage, typical of lupus. Symptoms can be mild or severe, affecting joints, skin, and organs.
Understanding the T cell imbalance is key to finding new treatments. By fixing this imbalance, researchers aim to improve lupus care.

A leading researcher said, “The T cell imbalance theory is a new way to understand lupus and other autoimmune diseases. It shows us new ways to treat them.” This highlights the importance of studying T cell imbalance in lupus.
Recent studies have uncovered the role of type I interferon in lupus, a complex autoimmune disease. This protein is key in the body’s immune response. Knowing how it affects lupus is vital for finding new treatments.
Interferons are proteins that help fight off viruses. Type I interferon is essential for starting an immune response. It activates immune cells and triggers the production of proteins to combat infections.
In a healthy immune response, type I interferon is controlled to avoid damage. But in autoimmune diseases like lupus, this control is lost.
Research links excess type I interferon to lupus. The blocked aryl hydrocarbon receptor (AHR) stops healing T cells. It also boosts T cells that make autoantibodies, attacking healthy cells. This imbalance leads to lupus symptoms.

The table shows how type I interferon works differently in a healthy immune response versus lupus. Understanding this difference is key to creating treatments that reduce the harm caused by excess type I interferon in lupus patients.
Recent studies have shown the aryl hydrocarbon receptor (AHR) is key in immune regulation. It helps our body handle environmental factors and bacteria. This makes it a focus in studying autoimmune diseases like lupus.
The AHR is a protein that turns on or off genes involved in immune response and inflammation. It keeps the immune system in balance by controlling immune cells, like T cells.
The AHR is vital for a healthy immune system. It helps in making Tregs, which stop autoimmunity. When AHR is active, it reduces inflammation and promotes immune tolerance.
When AHR is blocked, the immune system gets out of balance. This stops the production of healing T cells. Without enough AHR, the immune system can attack itself, causing diseases like lupus.
The key points to consider are:
Understanding AHR’s role in lupus could lead to new treatments. These treatments could help restore immune balance and prevent autoimmunity.
The new discovery about lupus helps us understand what causes it. We now know more about how environment and genes play a part. This includes how they affect T cell balance.
Environmental factors can trigger lupus in some people. Exposure to chemicals like silica dust and UV light can upset T cell balance. Reducing exposure to these triggers might help manage the disease.
Genes also play a big role in lupus. Some genetic variations can mess with T cell function and balance. Understanding these genetic factors can help spot who’s at risk. It might even prevent lupus from starting.
Discovering the cause of lupus is changing how we treat it. This breakthrough means we can now tackle lupus at its source. It’s not just about managing symptoms anymore.
With this new knowledge, several promising treatments are being explored.
One strategy is to fix the T cell imbalance in lupus. This imbalance causes the disease. By balancing these cells, researchers aim to lessen lupus’s impact. Targeted therapies could offer better treatment options.
Research also looks into blocking interferon. This is because too much Type I Interferon leads to lupus. Interferon-blocking therapies might reduce lupus severity.
The Aryl Hydrocarbon Receptor (AHR) is another focus. Studies show that controlling AHR could manage the immune system. AHR-targeting therapies might offer a new way to treat lupus.

Lupus management today has its good points but also areas for growth. We’ve made progress in treating this autoimmune disease. Yet, we’re far from having the best treatments yet.
Today’s lupus treatments mainly aim to ease symptoms, not fix the root cause. They include corticosteroids, immunosuppressants, and NSAIDs. These drugs help but can cause serious side effects. For example, long-term use of corticosteroids can harm bones, eyes, and increase infection risk.
