| abstractText | Vascular remodeling characterized by hyperproliferative neointima formation is an unfavorable repair process that is triggered by vascular damage. This process is characterized by an increased local inflammatory and proliferative response that critically involves the pro-inflammatory cytokine interleukin-1beta (IL-1beta). IL-1beta is expressed and cytosolically retained as a procytokine that requires additional processing prior to exerting its pro-inflammatory function. Maturation and release of pro IL-1beta is governed by a cytosolic protein scaffold that is known as the inflammasome. Here we show that NLRP3 (NOD-like receptor family, pryin domain containing 3), an important activating component of the inflammasome, is involved in neointima formation after vascular injury. NLRP3 deficiency itself does not affect the functional cardiovascular phenotype and does not alter peripheral differential blood counts. However, neointima development following wire injury of the carotid artery was significantly decreased in NLRP3-deficient mice as compared to wild-type controls. In all, NLRP3 plays a non-redundant role in vascular damage mediated neointima formation. Our data establish NLRP3 as a key player in the response to vascular damage, which could open new avenues to therapeutic intervention. |
