Systemic inflammatory response condition known as sepsis can cause fatal organ damage. Although modern intensive care has improved, severe sepsis still has a death rate that surpasses 30% overall. It is the third most common cause of death, behind cancer and cardiovascular disease. Failure of multiple organs, particularly the lung, liver, and kidney, causes death from severe sepsis. The systemic inflammation caused by Lipopolysaccharide (LPS) mimics many of the early clinical signs of sepsis. Additionally, kidney harm and microcirculatory failure are caused by its exposure. There is currently no effective treatment for acute renal damage brought on by sepsis. To combat this agonising condition, novel therapeutic strategies are urgently needed. The current studies were carried out on male, albino, wild- type Swiss mice weighing 20–30 g to examine the potential mechanism(s) underlying AKI following intraperitoneal administration of LPS (1 mg/kg) and the impact of various therapeutic approaches using baicalin (50 mg/kg; i.p.) as a toll- like receptor (TLR)4 inhibitor, parthenolide (10 mg/kg/day, i.p.) as an antiinflammatory [1]. Each medication was given three times, 48, 24, and 3 hours before the injection of LPS. We assessed oxidative stress, highmobility group box 1 (HMGB1), and inhibitor of nuclear factor- kappa B (NF- B) alpha (IB) RNA expression in the kidney. The research was conducted in accordance with the ethics committee's recommendations.
TLRs play a significant role in the development of inflammation in sepsis because they identify a wide variety of microbes, as well as biological components released as a result of tissue damage and innate immune responses. Through the suppression of TLR4, the flavonoid molecule baicalin, which is derived from plants, has been demonstrated to be a powerful antagonist of the biochemical and physiological effects of LPS. Baicalin has antibacterial, anti- inflammatory, and antioxidant properties. HMGB1 can enhance the effects of TLR ligand signals and may potentially behave as a TLR ligand itself. In the expression of additional proinflammatory genes, including as cytokines, chemokines, and adhesion molecules, nuclear Factor- B (NF- B) has long been regarded as an archetypal proinflammatory signalling pathway. According to a potential parthenolide mode of action, IKK- , an NF- B activator, is blocked in order to suppress the NF- B pathway. A crucial part of pro-inflammatory cytokine- mediated signalling is played by the IKK-complex [2]. Lipopolysaccharide (LPS) is known to elevate renal Fas and Fas- ligand expression, which in turn activates both intrinsic and extrinsic apoptotic pathways. These effects are known to raise oxidative stress indicators. The caspase enzyme cascade is one of the several mediators of the intricate process of apoptosis and is crucial to both the generation of a number of inflammatory cytokines and apoptosis. The capacity of powerful peptide- based macromolecular inhibitors like ZVAD to block multiple caspases may explain their effectiveness in clinical models of illness. Inflammatory tissues have been found to have high levels of cyclooxygenase (COX)- 2, which creates prostaglandins that promote inflammation (PG). NF- B binding regions in the COX- 2 gene's promoter region are essential for transcriptional activation. As a result, higher COX- 2 activity brought on by LPS is caused by a selective rise in COX- 2 protein levels, indicating that increased PG and thromboxanes synthesis is caused by up- regulation of COX- 2 [3].
The current study demonstrated that LPS had a preconditioning effect, as evidenced by an increase in the anti- inflammatory interleukin (IL)- 10, a decrease in the pro- inflammatory IL- 1, an increase in the gene expression of the inhibitor of nuclear factor- kappa B (NF- B) alpha (IB), and a decrease in the gene expression of HMGB1. In the early phase as opposed to the late phase, this preconditioning was more prevalent. This preconditioning didn't take oxidative stress or apoptotic pathways into account. The fact that preconditioning's effects did not last beyond the 24- hour phase may be the reason why LPS treatment caused death. In the current study, pretreatment with baicalin, parthenolide, SC- 58125, or Z- VAD reduced the severity of LPSinduced AKI as shown by reduced kidney functional impairment [4]. It also countered the state of oxidative stress, increased the preconditioning effects of LPS, improved apoptotic cell death, and improved kidney histopathologic changes. These studied substances' antioxidant and/or anti- inflammatory capabilities may have contributed to their nephroprotective effects. Studies on histopathology supported the earlier findings. The most effective medications that improved survival % at 24 h- phase were parthenolide, SC58125, and Z- VAD. Baicalin and parthenolide have an advantage over other therapies in that they are derived from plant sources, which could lessen any negative effects. The suggested follow- up study can be planned to shed some light on whether the combination of various medications with various mechanisms could offer a promising effect against LPS- induced AKI and further improve survival rates or even prevent death due to Gram negative bacteria, particularly in intensive care units [5].
