Recent research has helped us learn a lot about autoimmune diseases. These diseases happen when the body's immune system mistakenly attacks its own healthy cells. Here are some important points about what we know now:
Genetic Factors: Scientists have found over 100 genes linked to autoimmune diseases through a type of study called genome-wide association studies (GWAS). One important gene, HLA-DRB1, is connected to a higher chance of getting rheumatoid arthritis. It is believed that about 30% of this disease can be connected back to this gene.
Environmental Triggers: Some outside factors can start these diseases. For instance, certain infections, like the Epstein-Barr virus, are linked to multiple sclerosis. A study showed that 60% of people with lupus, a kind of autoimmune disease, reported having infections before they got sick.
Immune Dysregulation: When the immune system doesn't work properly, it can forget how to tell the difference between healthy cells and harmful ones. This confusion can lead to diseases like Type 1 diabetes. Some groups of immune cells called Tregs might be missing or not working right.
Biomarkers: Doctors can now measure specific markers, called autoantibodies, in the blood. For instance, the anti-CCP marker helps diagnose rheumatoid arthritis accurately about 87% of the time and correctly identifies those who don’t have it about 95% of the time.
Imaging Techniques: New imaging methods, like PET scans, are helping doctors find signs of autoimmune diseases earlier, especially in conditions like lupus and vasculitis.
Biologics: New drugs, called biologics, which include monoclonal antibodies like tocilizumab, are making a big difference for people with rheumatoid arthritis. In trials, up to 70% of patients saw a major improvement in their symptoms.
Cellular Therapies: Researchers are also looking into new treatments that use a type of immune cell called CAR-T cells. Although these are still being studied, they show promise for tackling tough autoimmune diseases.
As we continue to learn more about how autoimmune diseases work, future research and treatment will likely focus on personalized medicine. This means doctors will aim to create more tailored treatments to help each patient in the best way possible.
