Mutations in leucine-rich repeat kinase 2 (LRRK2) age-dependently cause Parkinson's disease and are associated with several inflammatory diseases. So far, the potential role of LRRK2 expression in glial cells as mediators of neuroinflammation and the influence of aging have not been investigated in viral vector-based LRRK2 animal models. In this study, we compared the effect of striatal injecti...
Missense mutations in the leucine-rich repeat kinase 2 (LRRK2) gene are the most common causes of both familial and sporadic forms of Parkinson disease and are also associated with diverse pathological alterations. The mechanisms whereby LRRK2 mutations cause these pathological phenotypes are unknown. We used immunohistochemistry with 3 distinct anti-LRRK2 antibodies to characterize the express...
Mutations in the gene encoding LRRK2 (leucine-rich repeat kinase 2) were first identified in 2004 and have since been shown to be the single most common cause of inherited Parkinson's disease. The protein is a large GTP-regulated serine/threonine kinase that additionally contains several protein-protein interaction domains. In the present review, we discuss three important, but unresolved, ques...
Interest in studying the biology of LRRK2 (leucine-rich repeat kinase 2) started in 2004 when missense mutations in the LRRK2 gene were linked to an inherited form of Parkinson's disease with clinical and pathological presentation resembling the sporadic syndrome. LRRK2 is a complex molecule containing domains implicated in protein interactions, as well as kinase and GTPase activities. The obse...
Mutations in LRRK2 (leucine-rich repeat kinase 2) are a relatively common cause of inherited PD (Parkinson's disease), but the mechanism(s) by which mutations lead to disease are poorly understood. In the present paper, I discuss what is known about LRRK2 in cellular models, focusing specifically on assays that have been used to tease apart the effects of LRRK2 mutations on cellular phenotypes....
Mutations in the leucine-rich repeat kinase 2 gene (LRRK2) cause late-onset Parkinson's disease (PD) with a clinical appearance indistinguishable from idiopathic PD. Initial studies suggest that LRRK2 mutations are the most common yet identified determinant of PD susceptibility, transmitted in an autosomal-dominant mode of inheritance. Herein, we characterize the LRRK2 gene and transcript in hu...
Mutations in leucine-rich repeat kinase 2 gene (LRRK2) are associated with familial and sporadic Parkinson's disease (PD). LRRK2 is a complex protein that consists of multiple domains, including 13 putative armadillo-type repeats at the N-terminus. In this study, we analyzed the functional and molecular consequences of a novel variant, E193K, identified in an Italian family. E193K substitution ...
In response to brain injury, microglia rapidly extend processes that isolate lesion sites and protect the brain from further injury. Here we report that microglia carrying a pathogenic mutation in the Parkinson's disease (PD)-associated gene, G2019S-LRRK2 (GS-Tg microglia), show retarded ADP-induced motility and delayed isolation of injury, compared with non-Tg microglia. Conversely, LRRK2 knoc...
LRRK2, a gene relevant to Parkinson's disease, encodes a scaffolding protein with both GTPase and kinase activities. LRRK2 protein is itself phosphorylated and therefore is subject to regulation by cell signalling; however, the kinase(s) responsible for this event have not been definitively identified. Here using an unbiased siRNA kinome screen, we identify and validate casein kinase 1α (CK1α) ...
BACKGROUND Mutations in the LRRK2 gene are an important cause of familial and nonfamilial parkinsonism. Despite pleomorphic pathology, LRRK2 mutations are believed to manifest clinically as typical Parkinson disease (PD). However, most genetic screens have been limited to PD clinic populations. OBJECTIVE To clinically characterize LRRK2 mutations in cases recruited from a spectrum of neurodeg...
