Understanding RNP-Sm antibody
Sm (Smith) and RNP (U1-ribonucleoprotein) are proteins found inside cells that play a role in RNA processing. In some autoimmune conditions, the immune system mistakenly produces antibodies that target these proteins. The presence of Sm and RNP antibodies in the blood may indicate abnormal immune activity and is considered a useful marker for certain connective tissue diseases.
The Sm antibody is highly specific for systemic lupus erythematosus (SLE), though not present in all SLE patients. RNP antibodies are stro...
