Abstract: Recently, cytokines belonging to C1q/tumour necrosis factor‐related proteins (CTRPs) superfamily have attracted increasing attention due to multiple metabolic functions and desirable anti‐inflammatory effects. These various molecular effectors exhibit key roles upon the onset of cardiovascular diseases, making them novel adipo/cardiokines. This review article aimed to highlight recent findings correlated with therapeutic effects and additional mechanisms specific to the CTRP9, particularly in cardiac ischaemia… Show more

Peripheral nerve injury triggers rapid microglial activation, promoting M1 polarization within the spinal cord, which exacerbates the progression of neuropathic pain. C1q/TNF-related protein 9 (CTRP9), an adiponectin homolog, is known to suppress macrophage activation and exhibit anti-inflammatory properties through the activation of adiponectin receptor 1 (AdipoR1) in various disease contexts. Nevertheless, the involvement of CTRP9 in microglial polarization in the context of neuropathic pain is still unclear. Our study aimed to how CTRP9 influences spinal microglial polarization, neuroinflammation, and pain hypersensitivity, as well as the underlying mechanism, using a neuropathic pain model in male mice with spared nerve injury (SNI) of sciatic nerve. Our findings revealed SNI elevated the spinal CTRP9 and AdipoR1 levels in microglia. Furthermore, intrathecal administration of recombinant CTRP9 (rCTRP9) substantially weakened mechanical hypersensitivity and heat-related pain response triggered by SNI. On the other hand, rCTRP9 mediated a phenotypic switch in microglia, from the pro-inflammatory M1 state to the anti-inflammatory M2 state, by influencing the spinal AMPK/NF-κB mechanism in SNI mice. Additionally, treatment with AdipoR1 siRNA or an AMPK-specific antagonist both reversed the effects of CTRP9 on the phenotypic switching of spinal microglia and pain hypersensitivity. Collectively, these results indicate that CTRP9 ameliorates mechanical hypersensitivity and heat-related pain response, shifted the balance of microglia towards the anti-inflammatory M2 state, and suppresses neuroinflammatory responses by modulating the AMPK/NF-κB pathway, mediated by AdipoR1 activation, in mice with SNI.

Recently, cytokines belonging to C1q/tumour necrosis factor‐related proteins (CTRPs) superfamily have attracted increasing attention due to multiple metabolic functions and desirable anti‐inflammatory effects. These various molecular effectors exhibit key roles upon the onset of cardiovascular diseases, making them novel adipo/cardiokines. This review article aimed to highlight recent findings correlated with therapeutic effects and additional mechanisms specific to the CTRP9, particularly in cardiac ischaemia/reperfusion injury (IRI). Besides, the network of the CTPR9 signalling pathway and its possible relationship with IRI were discussed. Together, the discovery of all involved underlying mechanisms could shed light to alleviate the pathological sequelae after the occurrence of IRI.

Background: C1q/tumor necrosis factor-related protein-9 (CTRP9) is critically involved in the pathophysiology of metabolic and cardiovascular disorders. This investigation aimed to clarify the mechanism underlying the role of CTRP9 in atherosclerosis in apolipoprotein E (ApoE) knockout (KO) mice. Methods: ApoE KO mice were fed a Western diet and injected with a virus which resulted in CTRP9 overexpression or knockdown for 12 weeks. The plasma lipid levels and atherosclerotic plaque areas were measured after the mice were euthanized. Aortas were isolated, and RNA sequencing was performed to identify the differentially expressed genes and related signaling pathways. Finally, plasma oxidative stress factors were measured to demonstrate the reliability of the RNA sequencing results. Results: The plasma lipid levels in the CTRP9 overexpression group did not significantly differ from those in the green fluorescence protein (GFP) group. Markablely, CTRP9 overexpression inhibited atherosclerotic plaque formation in ApoE KO mice, whereas CTRP9 knockdown promoted plaque formation. RNA sequencing analysis identified 3485 differentially expressed genes that were prominently enriched across 55 signaling pathways. Additionally, plasma oxidative stress factors were significantly reduced after CTRP9 overexpression, whereas these factors were increased after CTRP9 knockdown, which was consistent with the results of the RNA sequencing analysis. Conclusions: These findings demonstrated that CTRP9 alleviated inflammation and cholesterol metabolism, which reduced oxidative stress in an atherosclerotic animal model. These beneficial effects may mediate the suppression of lesion development in the aorta.
