Recent studies show that guidance molecules that are known to regulate cell
migration during development may also play an important role in adult
pathophysiologic states. One such molecule, semaphorin3A (sema3A), is highly
expressed after acute kidney injury (AKI) in mice and humans, but its
pathophysiological role is unknown. Genetic inactivation of sema3A protected mice
from ischemia-reperfusion-induced AKI, improved tissue histology, reduced
neutrophil infiltration, prevented epithelial cell apoptosis, and increased
cytokine and chemokine excretion in urine. Pharmacological-based inhibition of
sema3A receptor binding likewise protected against ischemia-reperfusion-induced
AKI. In vitro, sema3A enhanced toll-like receptor 4-mediated inflammation in
epithelial cells, macrophages, and dendritic cells. Moreover, administration of
sema3A-treated, bone marrow-derived dendritic cells exacerbated kidney injury.
Finally, sema3A augmented cisplatin-induced apoptosis in kidney epithelial cells
in vitro via expression of DFFA-like effector a (cidea). Our data suggest that
the guidance molecule sema3A exacerbates AKI via promoting inflammation and
epithelial cell apoptosis.
