Abstract
Background
Leucine-rich repeat kinase 2 (LRRK2) is a recently discovered molecule associated with familial and sporadic Parkinson’s disease. It regulates many central neuronal functions such as cell proliferation, apoptosis, autophagy, and axonal extension. However, in contrast to the well-documented function of LRRK2 in central neurons, it is unclear whether LRRK2 is expressed in enteric neurons and affects the physiology of the gut.
Aims
By examining LRRK2-KO mice, this study investigated whether enteric neurons express LRRK2 and whether intestinal neuronal peptides and IgA are quantitatively changed.
Methods
Intestinal protein lysates and sections prepared from male C57BL/6 J mice were analyzed by Western blotting and immunostaining using anti-LRRK2 antibody, respectively. Intestinal neuronal peptide-mRNAs were quantified by real-time PCR in wild-type mice and LRRK2-KO mice. Intestinal IgA was quantified by ELISA. Lamina propria mononuclear cells (LPMCs) were analyzed by flow cytometry to evaluate the ratio of B1 to B2 B cells.
Results
Western analysis and immunostaining revealed that LRRK2 is expressed in enteric neurons. The amounts of mRNA for vasoactive intestinal peptide, neuropeptide Y, and substance P were increased in LRRK2-KO mice accompanied by an increment of IgA. However, the intestinal B cell subpopulations were not altered in LRRK2-KO mice.
Conclusions
For the first time, we have revealed that LRRK2 is expressed in enteric neurons and related to quantitative alterations of neuronal peptide and IgA. Our study highlights the importance of LRRK2 in enteric neurons as well as central neurons.
