Evidence 0bbe3552aa

Using a similar mouse model, Shi et al. treated animals with the antimalarial drug artemisinin, showing that this treatment results in inhibition of NFkB and presumably the NLRP3 inflammasome (13)

Evidence 59a19beec8

One of the canonical pathways of this innate immune response evoked by Abeta is the activation of the NOD-like receptor (NLR) family, pyrin domain containing 3 (NLRP3) inflammasome that became a focus of intense research

Evidence 45ab01cddf

NLRP3 inflammasome activation results from TLR ligation and concomitant uptake of Ab in models of AD

Evidence 7075cabccc

NLRP3 inflammasome formation and subsequent activation of caspase-1 cleavage capacity was instrumental for Abeta-induced nitric oxide production and TNF-a release

Evidence 16e460d34e

Further data, showing “neuronal pyroptosis” of Abeta exposed neurons in a NLRP1- dependent and caspase-1-mediated manner may point to a vicious cycle, by which NLRP1 is causing neurodegeneration in response to increased Abeta production (14)

Evidence 98c28d00d0

Using the herbizide, N,N0-dimethyl-4,40-bipyridinium dichloride (paraquat) as a mitochondrial toxin, which is known to induce oxidative stress, Chen et al. found increased levels of caspase-1 and IL-1b in brain of wild type and APP/PS1 transgenic mice (2), suggesting that those were due to NLRP3 inflammasome activation

Evidence 8dee3ee6f2

Activation of the NLRP3 inflammasome by fibrillar Abeta has been described first by Halle et al. in 2008

Evidence 9362ed59d1

Recently, Kaushal et al. described the involvement of NLRP1 inflammasome activation in neurons. In these experiments, serum deprivation induced NLRP1-dependent caspase-1 activity and ASC speck formation, which resulted in caspase-6 activation and an increase in the Ab42/total Ab ratio (11)

Evidence b2536463bd

Activation of NLRP3 leads to the generation of interleukin-1b (IL-1b) and interleukin 18 (IL-18), which are being cleaved by caspase-1 from their inactive precursors and subsequently

Evidence 0a6311323d

This finding was associated with spatial memory dysfunction and an increase in Abeta plaque deposition

Evidence 0f066f7f51

Soluble Abeta (sAbeta)-induces NLRP3 inflammasome activation, however it requires the presence of the surface receptor CD36 (12)

Evidence 1fd9bb5b8b

NLRP3 activation was characterized by ASC speck formation in an immune-activated microglial cell line and required a dual signal to become effective: the phagocytic uptake of Abeta and cathepsin B release after lysosomal disruption

Evidence 422b3bad7c

The combined effect of the increased IDE production and phagocytic Abeta clearance reduced the cerebral Abeta load substantially, even at late life. Since immunohistochemistry found NLRP3 exclusively expressed in microglial cells, it has been concluded that the observed changes were entirely due to NLRP3 inflammasome modulation in these cells
