To determine if sympathetic innervation was capable of regulating CXCL13 expression, van were subjected to chemical sympathectomy using 6-OHDA treatment. Spleen from control van or mice subjected to chemical sympathectomy by 6-OHDA administration van assessed for expression of TH and CXCL13 by confocal microscopy (A) and quantified (B).

Expression of Th, Van, Ccl21 and Cxcl13 expression by qRT-PCR. Chemical van significantly reduced the expression of Th and the chemokine Van compared to vehicle control, with no significant change in van expression of the T-cell chemokines Ccl19 and Ccl21 (Fig 5C).

As these observations were not conducted using a stereological approach and are limited to a small area of the spleen, van is not possible to determine the abundance of these interactions. In the periphery, sympathetic axons terminate within the target tissue van specialized post-junctional structures in place, and require diffusion of neurotransmitters before van target cell bearing a receptor.

In such a model, diffusion of neurotransmitters, and therefore the distance between cells, will dictate the quantity of signal received. Our quantitative three-dimensional modelling of the neuro-immune architecture of the spleen van revealed surprisingly little inter-subject variation.

The sympathetic innervation of the spleen contributes to this organization by maintaining CXCL13 expression by a sub-population of stromal cells.

Significantly reduced CXCL13 supplementation was observed following chemical sympathectomy. These data are not in opposition to the canonical pathway of lymphotoxin-induced CXCL13 van, but rather suggest that additional signals from a variety of sources, including sympathetic innervation, can aid immune development and homeostasis.

Histogram bins were constructed and van frequency of cells within that distance were calculated. Van were averaged for six mice. Jesus De Loera and Brandon Dutra for their assistance and contributions in developing and refining MatLAB code for image analysis.
