The Parkinson's disease-associated protein, Leucine-rich repeat kinase 2 (LRRK2), a known negative regulator of nuclear factor of activated T cells (NFAT), is expressed in myeloid cells such as macrophages and dendritic cells (DCs) and is involved in the host immune response against pathogens. Since, the Ca2+ /NFAT/IL-2 axis has been previously found to regulate DC response to the fungus Aspergillus , we have investigated the role played by the kinase LRRK2 during fungal infection. Mechanistically, we found that in the early stages of the non-canonical autophagic response of DCs to the germinated spores of Aspergillus , LRRK2 undergoes progressive degradation and regulates NFAT translocation from the cytoplasm to the nucleus...
