    Proposed mechanism of lipopolysaccharide (LPS) activation in BIA-ALCL via TLR4 pathway. LPS activation of BIA-ALCL cells occurs through an alternative TLR4 pathway rather than T-cell receptor activation whereby the cells no longer require antigen presentation and processing by an APC. This complex is then able to directly activate T-cells, producing a downregulation of the immune response as a means to increase bacterial survival.
