Hughes et al. investigate the TLR4-mediated inflammatory response in Alzheimer’s disease and show that picomolar concentrations of soluble amyloid beta aggregates lead to a sensitised response of TLR4 with time, resulting in increased TNF-α production. They suggest the use of near physiological concentration of soluble aggregates can cause long-term potentiation deficit and neuronal death through an autocrine/paracrine mechanism due to TLR4 signalling.
