abstract = {Physical exercise has well-established anti-inflammatory
effects, with neuro-immunological crosstalk being proposed
as a mechanism underlying the beneficial effects of exercise
on brain health. Here, we used physical exercise, a strong
positive modulator of adult hippocampal neurogenesis, as a
model to identify immune molecules that are secreted into
the blood stream, which could potentially mediate this
process. Proteomic profiling of mouse plasma showed that
levels of the chemokine lymphotactin (XCL1) were elevated
after four days of running. We found that XCL1 treatment of
primary cells isolated from both the dentate gyrus and the
subventricular zone of the adult mice led to an increase in
the number of neurospheres and neuronal differentiation in
neurospheres derived from the dentate gyrus. In contrast,
primary dentate gyrus cells isolated from XCL1 knockout mice
formed fewer neurospheres and exhibited a reduced neuronal
differentiation potential. XCL1 supplementation in a dentate
gyrus-derived neural precursor cell line promoted neuronal
differentiation and resulted in lower cell motility and a
reduced number of cells in the S phase of the cell cycle.
This work suggests an additional function of the chemokine
XCL1 in the brain and underpins the complexity of
neuro-immune interactions that contribute to the regulation
of adult hippocampal neurogenesis.},
