Esponses immediately after SCI have already been evaluated histologically making use of rodent contusion models. Data acquired via this strategy have already been a foundation for pre-clinical neuroprotective research and early-phase human clinical trials.13,30,31 Here, we utilized CSF to assess cytokine and chemokine profiles in a naturally occurring, clinically relevant, large-animal kind of compressive/contusive SCI. You’ll find limitations inherent to applying naturally occurring disease in which lots of animals survive SCI, like variation in anatomical level of injury, pretreatment with drugs which will modulate immune responses, and lack of available histological samples. Nonetheless, our outcomes largely confirm the involvement of IL-8 and MCP-1 in SCI pathogenesis and highlight the possibility of targeting these molecules in canine pre-clinical trials. Conclusion CSF cytokines and chemokines involved in innate inflammatory responses are dysregulated following naturally occurring, acute thoracolumbar SCI in dogs. CSF IL-8 was elevated and correlated to duration of SCI ahead of sampling, as has been observed in humans with SCI, but an association in between measurements of neurological recovery and CSF IL-8 was not detected. CSF MCP1, which is elevated in humans with SCI, was positively correlated to CSF microprotein and RBC concentrations and was connected with neurological recovery at day 42 immediately after SCI. These data would suggest that neuroinflammatory processes in humans and dogs with SCI do share certain broad parallels. The mechanisms underlying the decreased CSF IP-10 and IL-18 concentrations in SCI dogs, when compared with controls, are unclear and merit further evaluation.
