Double-stranded DNA (dsDNA) antibodies are autoantibodies that target the body’s own genetic material - specifically, the double-helix structure of DNA inside the cell nucleus.
A dsDNA antibody (anti-double-stranded DNA antibody) is an autoantibody your immune system makes when it mistakenly targets the double-helix of your own DNA. This reflects a breakdown in “self” vs “non-self” recognition. dsDNA antibodies are strongly associated with systemic lupus erythematosus (SLE) and can form immune complexes that deposit in organs like the kidneys, joints, skin, and blood vessels, driving inflammation and tissue damage.
