Ankylosing spondylitis (AS) is a type of arthritis and autoimmune condition that causes inflammation and pain in the joints, especially in the spine.
While the exact cause of AS is not known, researchers believe that a combination of genetic and environmental factors may play a role.
Genetic factors are thought to be a significant contributor to the development of AS.
Specifically, people who have with the gene HLA-B27 are more likely to develop AS than those who do not have the gene.
HLA-B27 is involved in the immune system’s response to infections, and it is believed that having this gene may make the immune system more likely to attack the joints and cause inflammation.
However, not everyone who has the HLA-B27 gene will develop AS.
Researchers believe that other genetic factors may also be involved in the development of the condition.
There are studies which have identified several other genes that may increase the risk of developing AS, including genes involved in the immune system and inflammation.
Environmental factors may also play a role in the development of AS.
One environmental factor that has been linked to AS is a bacterial infection in the gut called Klebsiella pneumoniae.
Some researchers believe that people who have a genetic predisposition to AS may be more susceptible to this type of infection, and that the infection can trigger the immune system to attack the joints.
Other environmental factors that may contribute to the development of AS include smoking, which can increase inflammation in the body, and repetitive or physically demanding work, which can lead to joint damage over time.
In addition to genetic and environmental factors, researchers believe that the immune system plays a key role in the development of AS.
In ankylosing spondylitis patients, the immune system appears to be overactive, and it attacks the joints and surrounding tissues, causing inflammation and pain.
Specifically, the immune system produces proteins called cytokines, which play a role in inflammation.
For people with AS, certain cytokines are overproduced, leading to inflammation in the joints and other tissues.
Researchers are studying these cytokines to develop new treatments for AS that target the specific proteins involved in inflammation.

While the exact cause of AS is not known, it is believed to be related to a combination of genetic and environmental factors, as well as an overactive immune system that attacks the joints and surrounding tissues.
Understanding the causes of AS is essential for developing new treatments and improving outcomes for people with this condition.
