Missense mutations in the leucine-rich repeat kinase-2 (LRRK2) gene represent the most common cause of autosomal dominant Parkinson's disease (PD). In the years LRRK2 has been associated with several organelles and related pathways in cell. However, despite the significant amount of research done in the past decade, the contribution of LRRK2 mutations to PD pathogenesis remains unknown. Growing evidence highlights that LRRK2 controls multiple processes in brain immune cells, microglia and astrocytes, and suggests that deregulated LRRK2 activity in these cells, due to gene mutation, might be directly associated with pathological mechanisms underlying PD. In this brief review, we recapitulate and update the last LRRK2 functions dissected in microglia and astrocytes. Moreover, we discuss how dysfunctions of LRRK2-related pathways may impact glia physiology and their cross-talk with neurons, thus leading to neurodegeneration and progression of PD.

Depicted as playing cards belonging to the same suit, the paralogous MLL3 and MLL4 lysine methyltransferase (KMT) complexes share a common set of core and auxiliary subunits as well as similar histone methylase functions. On each card, largely divergent processes are described on opposing sides – highlighting the potential capacity of these KMT complexes to participate in both tumor-supportive and tumor-suppressive mechanisms. To understand how MLL3 and MLL4 can regulate such diverse and sometimes contrasting processes, read more in this review article by Wang and colleagues (pp. 1041–1054).
