Alirocumab
Based on 1 publication(s) in Google Scholar
Alirocumab is an anti-PCSK9 human monoclonal antibody. Alirocumab inhibits PCSK9. Alirocumab reduces NLRP3 inflammasome, regulates Nrf2/HO-1, HMGB1/NF-κB and Fractalkine/CX3CR1. Alirocumab increases the ability of the liver to bind LDL-cholesterol (LDL-C) and reduces levels of LDL-C in blood. Alirocumab improves atherosclerosis and inflammation.

Alirocumab (40 μg/mL, 24 h) alleviates basal PCSK9 overexpression in vascular smooth muscle cells (VSMCs) of obese insulin-resistant Zucker rats (OZR)[3].
Alirocumab (8 μg/mL, 72 h) attenuates Lp(a) secretion in primary human hepatocytes via inhibition of PCSK9[4].
Alirocumab (10 μg/mL, 24 h) inhibits lipid-induced inflammation in HepG2 cells[5].

Result:Decreased PCSK9 protein levels by 65.3%.
Attenuated increased IL-6, IL-1β, and TNFα protein levels.
Decreased p65-NF-κB phosphorylation.
Reduced the phosphorylation levels of AP-1 by 61.0%.
Decreased the phosphorylation levels of PI3K and AKT.
Decreased the mTOR protein phosphorylation levels by 46.2%.
Alirocumab (16 mg/kg/week, s.c., on day 0, day 7, and day 14) boosts antioxidant status and halts inflammation in rat model of sepsis-induced nephrotoxicity via modulation of Nrf2/HO-1, PCSK9/HMGB1/NF-ᴋB/NLRP3 and Fractalkine/CX3CR1 hubs[7].
Alirocumab (50 mg/kg, s.c., weekly prior to exposure to the liquid diets) attenuates ethanol-induced neuronal injury in the brain and oxidative stress in rats[8].
Alirocumab (1 mg/kg/week, s.c.) activates brown fat, increases hepatic uptake of cholesterol-rich TRL remnants, thereby lowering non-HDL-C, and increases HDL-C levels and cholesterol efflux capacity of HDL, further improving dyslipidemia in APOE*3-Leiden.CETP mice[9].
Alirocumab (10 mg/kg, s.c., 2 weeks) reduces lipoprotein(a) levels in nonhuman primates by lowering apolipoprotein(a) production rate[10].
Alirocumab (3-10 mg/kg, i.p., weekly for 16 weeks) reduces RAS, NLRP3 inflammasome, and cholecystokinin in lung tissue of obese mice[11].

Result:Mitigated LPS-mediated increments in serum creatinine and cystatin C, together with renal contents of both KIM-1 and NGAL.
Restored renal NGAL content to its normal values.
Boosted mRNA expression levels of both Nrf2 and HO-1 and renal TAC content (2.5, 2, and 3.2-folds, respectively).
Produced pronounced hampering in LPS-mediated elevation in mRNA expression levels of PCSK9 and RAGE, along with renal contents of PCSK9 and HMGB1 by 80.9 %, 49.6 %, 53.1 % and 59.8 %, respectively.
Resulted in a marked reduction in the protein expression of TLR4, MYD88, and NLRP3, along with mRNA expression levels of NF-ᴋB by 62.9 %, 58.1 %, 50.9 %, respectively.
Caused remarkable alleviation in LPS-mediated increment in TNF-α, IL-1β, and caspase-1 by 48.5 %, 68.3 % and 58.5 %, respectively.
Produced prominent downregulation in mRNA expression levels of CX3CL1 and CX3CR1 by 88.4 % and 87.5 %, respectively.
Exhibited prominent elevation in mRNA expression level of Bcl-2 (1.7-folds), along with a marked reduction in both mRNA expression level of Bax and renal caspase-3 content (by 66.7 % and 58.5 %, respectively) .
Regressed glomerular and tubular lesions.
