WebMar 29, 2024 · IL-18BP deficiency is associated with elevated plasma levels of free IL-18 and an enhanced IFN-γ molecular signature in TLR9-induced MAS. Abstract The term macrophage activation syndrome (MAS) defines a severe, potentially fatal disorder characterized by overwhelming inflammation and multiorgan involvement. WebTLR9 has also been designated as CD289 ( cluster of differentiation 289). It is a member of the toll-like receptor (TLR) family. TLR9 is an important receptor expressed in immune system cells including dendritic cells, macrophages, natural killer cells, and other antigen presenting cells. [5]
