Abstract Abstract Background Inflammation may play an important role in atherosclerosis in familial hypercholesterolemia (FH). Lipopolysaccharide (LPS)-nuclear factor-kappa B (NF-κB) pathway is a routine signal process activated in inflammatory status. Purpose This study aimed to examine the LPS-NF-κB axis status and the impact of lipoprotein apheresis (LA) on this pathway in patients with FH and coronary artery disease (CAD). Methods In this matched case-control study a genetically diagnosed FH cohort who presented stable CAD (n=63) was compared with 63 non-FH CAD and 63 non-FH non-CAD controls matched by sex and age. Plasma LPS levels and NF-κB activity were compared among the three groups. In addition, we studied in vitro LPS-induced interleukin-6 (IL-6) production by mononuclear cells from 16 FH cases without previous statin use and compared them with their respective matched control groups. Subsequently, these 16 FH patients underwent LA. Blood samples were taken immediately before and regularly after LA for measuring LPS and NF-κB. Results FH plus CAD had higher LPS levels and NF-κB activity than CAD and non-CAD controls (all p values <0.01). LPS-induced IL-6 production by mononuclear cells of FH plus CAD was also much higher compared with CAD and non-CAD controls (both p values <0.01). Moreover, plasma LPS levels (p<0.001) and NF-κB activity (p<0.01) were dramatically reduced after apheresis in FH patients. Conclusion Genetically confirmed FH patients with CAD had a marked activation of LPS-NF-κB axis, while LA significantly attenuated this key inflammatory pathway, suggesting that inflammation may be an important therapeutic target for FH patients.

Hypertension is associated with low-grade inflammation, and Toll-like receptor 4 (TLR4) has been shown to be linked to the development and maintenance of hypertension. This study aimed to investigate the effects of scutellarin (administered by oral gavage daily for 2 weeks) on brain TLR4/nuclear factor kappa B-(NF-κB-) mediated inflammation and blood pressure in renovascular hypertensive (using the 2-kidney, 2-clip method) rats. Immunofluorescence and western immunoblot analyses revealed that hypertension contributed to the activation of TLR4 and NF-κB, accompanied by significantly enhanced expression of proinflammatory mediators, such as tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), and interleukin-18 (IL-18). Furthermore, expression of the antiapoptotic protein, myeloid cell leukemia-1 (Mcl1), was decreased, and the pro-apoptotic proteins, Bax and cleavedcaspase-3 p17 were increased in combined cerebral cortical/striatal soluble lysates. Scutellarin significantly lowered blood pressure and attenuated the number of activated microglia and macrophages in brains of hypertensive rats. Furthermore, scutellarin significantly reduced the expression of TLR4, NF-κB p65, TNF-α, IL-1β, IL-18, Bax and cleaved-caspase-3 p17, and increased the expression of Mcl1. Overall, these results revealed that scutellarin exhibits anti-inflammatory and anti-apoptotic properties and decreases blood pressure in hypertensive rats. Therefore, scutellarin may be a potential therapeutic agent in hypertension-associated diseases.

Introduction: Inflammation may play an important role in atherosclerosis in familial hypercholesterolemia (FH). Lipopolysaccharide (LPS)-nuclear factor-kappa B (NF-κB) pathway is a routine signal process activated in inflammatory status. Hypothesis: We assessed the hypothesis that LPS-NF-κB axis is markedly activated and lipoprotein apheresis has an inhibitory effect on this pathway in patients with FH and coronary artery disease (CAD). Methods: In this matched case-control study a genetically diagnosed FH cohort who presented stable CAD (n=63) was compared with 63 non-FH CAD and 63 non-FH non-CAD controls matched by sex and age. Plasma LPS levels and NF-κB activity were compared among the three groups. In addition, we studied in vitro LPS-induced interleukin-6 production by mononuclear cells from 16 FH cases without previous statin use and compared them with their respective matched control groups. Subsequently, these 16 FH patients underwent lipoprotein apheresis. Blood samples were taken immediately before and regularly after apheresis for measuring LPS and NF-κB. Results: FH plus CAD had higher LPS levels and NF-κB activity than CAD and non-CAD controls (all p <0.01). LPS-induced interleukin-6 production by mononuclear cells of FH plus CAD was also much higher compared with CAD and non-CAD controls (both p <0.01). Moreover, plasma LPS levels ( p <0.001) and NF-κB activity ( p <0.01) were dramatically reduced after apheresis in FH patients. Conclusions: In conclusion, genetically confirmed FH patients with CAD had a marked activation of LPS-NF-κB axis, while lipoprotein apheresis significantly attenuated this key inflammatory pathway, suggesting that inflammation may be an important therapeutic target for FH patients.

Osteoprotegerin (OPG), receptor activator of nuclear factor-kappa B (RANK) and receptor activator of nuclear factor-kappa B ligand (RANKL), the members of the tumor necrosis factor (TNF) family, have multiple effects on bone metabolism, endocrine functions and, as an inflammatory pathway, in the immune system. This study tried to determine the association of the OPG/RANKL/RANK axis with the severity of unstable angina (UA) as an inflammatory condition. Our study involved 50 patients with UA and 50 healthy people. Serum and peripheral blood mononuclear cells were isolated from all participants. Serum levels and gene expression of OPG, RANKL, and RANK in mononuclear cells were measured by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (RT-PCR), respectively. For each patient with UA, the thrombolysis in myocardial infarction (TIMI) and the global registry of acute coronary events (GRACE) scores were determined to evaluate the severity of the disease. Then we analyzed the relation of OPG, RANKL, and RANK levels with TIMI and GRACE scores in patients with UA. Discriminate analysis was used to predict the combinational models of such factors on the prediction of UA. Serum levels of OPG and RANKL (p<0.001) and gene expression of RANKL (p<0.001) were significantly more in patients than those in healthy ones. No relation was seen between the OPG/RANKL/RANK axis and the severity of UA according to TIMI and GRACE scores. Our study shows that serum level, as well as gene expression of OPG/RANKL/RANK axis neither, predicts the occurrence of UA nor shows any relationship with its severity.
