Mucin 1 is a cell-membrane associated mucin, expressed on epithelial and immune cells that helps protect against pathogenic infections. In humans, MUC1 is highly polymorphic, predominantly due to the presence of a variable number tandem repeat (VNTR) region in the extracellular domain that results in MUC1 molecules of typically either short or long length. A genetic link is known between these MUC1 polymorphisms and inflammation-driven diseases, although the mechanism is not fully understood. We previously showed that MUC1 on murine macrophages specifically restricts activation of the NLRP3 inflammasome, thereby repressing inflammation. This study evaluated the effect of MUC1 VNTR polymorphi..View full abstract
