Fig. 9. Model of nociceptor regulation of CRKP-induced pneumonic sepsis.

Fig. 9.

Lung-innervating nociceptor neurons suppress the recruitment of neutrophils and Ly6Chi monocytes to the airspaces of lungs during CRKP lung infection. CRKP infection induces vagal TRPV1+ neurons for releasing CGRP, which in turn acts on its receptor on Ly6Chi monocytes to dampen the ROS production. This leads to an increased CRKP survival in the lungs and enhanced dissemination of bacteria to vital organs. BioRender.com was used to create model.
