Effects of Campylobacter jejuni lipopolysaccharide on axonal injury in the spinal cord in rats.
To explore the effects of Campylobacter jejuni lipopolysaccharide (Cj-LPS) on axonal injury in the spinal cord. Wistar rats were divided into the control (NC) group, model group (Cj-LPS), and LPS antibody group (Anti-LPS). Rats in the NC group were injected with a mixture of normal saline and complete Freund's adjuvant (CFA) while those in Cj-LPS group were injected with Cj-LPS, composed of LPS, CFA, and saline. Rats were sacrificed at 4th week and 6th week after injection, and hematoxylin and eosin (HE) staining was performed on the spinal cord sections. Real time-reverse transcription(RT-PCR) was used to detect mRNA expression of the axonal nutrition factor neurotrophin-3 (NT-3) with its receptor tropomyosin receptor kinase C (TrkC) and axon inhibitory factor of NogoA/NgR (Nogo receptor). The results indicated that Cj-LPS induce axonal injury in the rat spinal cord, decreased the mRNA expression of the axonal nutrition factor NT-3/TrkC, and increased the mRNA expression of the inhibitory factor NogoA/NgR. However, anti-LPS ameliorated axonal injury in the rat spinal cord induced by Cj-LPS.
