BET Bromodomain Inhibition for Neuroinflammation Suppression

Mechanistic description

Mechanism / pathway

BRD4
→
neurodegeneration

Evidence for (5)

BRD4 occupancy at inflammatory gene promoters correlates with H3K27ac in AD microglia

PMID:31278196
BET inhibitor JQ1 reduces neuroinflammation and improves survival in ALS mouse models

PMID:26707847
BRD4 knockdown decreases α-synuclein-induced neurotoxicity in PD models

PMID:29617596
Pan-BET inhibition shows favorable brain penetration and anti-inflammatory effects in neurodegeneration models

PMID:25422509
ABBV-744 shows improved selectivity for BD4 over BD2/3, potentially reducing class-effect toxicities

PMID:29559673

Evidence against (4)

BBB penetration suboptimal - JQ1 has poor pharmaceutical properties for chronic CNS dosing

PMID:26707847
BRD4 regulates activity-dependent gene expression critical for synaptic plasticity and memory - broad inhibition could impair cognitive function in AD patients

PMID:29559673
Chronic BET inhibition causes thrombocytopenia and immune suppression as class effects

PMID:29559673
Inflammation is not universally detrimental - microglial surveillance functions could be impaired

PMID:29559673
