Remimazolam inhibits apoptosis of endothelial and epithelial cells by activating the PI3K/AKT pathway in acute lung injury
Background
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are significant burdens on global health. Remimazolam (REM), a novel sedative, has shown potential in its anti-inflammatory effects. However, a lack of evidence currently hinders our ability to determine if REM can improve ALI/ARDS.
Methods
We initially evaluated REM’s impact on lung injury in a lipopolysaccharide (LPS)–induced ALI mouse model. Subsequently, a network pharmacology (NP) strategy and ribonucleic acid–sequencing (RNA-seq) technique were used to investigate the potential molecular mechanisms underlying REM’s action against ALI. Finally, we carried out in vivo and in vitro experiments to validate our findings on these mechanisms.
Results
REM effectively mitigated lung injury in the mouse model. NP and RNA-seq analyses revealed significant enrichment of apoptosis-related pathways. Both in vivo and in vitro experiments revealed that REM significantly reduced levels of cleaved cysteine–aspartic acid–specific protease/proteinases 7 and 3 (cleaved Caspases-7 and −3) and cytochrome c (Cyt c) while enhancing the B-cell lymphoma 2 (Bcl-2)/Bcl-2–like protein 4 (Bax) ratio and phosphorylated protein kinase B (P-AKT) levels in lung tissue, endothelial cells, and epithelial cells. Furthermore, in vitro experiments confirmed that inhibiting the phosphoinositide 3-kinase (PI3K)/AKT pathway with LY294002 weakened REM’s antiapoptotic effects. In addition, pretreatment with PK11195 (the ligand of 18-kDa translocator protein [TSPO]) attenuated REM’s upregulation of the PI3K/AKT pathway and antiapoptotic effect in LPS-induced endothelial cells.
Conclusions
This study presents novel findings elucidating the beneficial effect of REM in ALI. This effect can be attributed to REM’s ability to inhibit apoptosis by activating of the PI3K/AKT pathway in endothelial and epithelial cells. Additionally, REM targeted TSPO to regulate this pathway in endothelial cells. These results suggested a potential protective role for REM in ALI/ARDS management.
期刊介绍:
International Immunopharmacology is the primary vehicle for the publication of original research papers pertinent to the overlapping areas of immunology, pharmacology, cytokine biology, immunotherapy, immunopathology and immunotoxicology. Review articles that encompass these subjects are also welcome.
The subject material appropriate for submission includes:
• Clinical studies employing immunotherapy of any type including the use of: bacterial and chemical agents; thymic hormones, interferon, lymphokines, etc., in transplantation and diseases such as cancer, immunodeficiency, chronic infection and allergic, inflammatory or autoimmune disorders.
• Studies on the mechanisms of action of these agents for specific parameters of immune competence as well as the overall clinical state.
• Pre-clinical animal studies and in vitro studies on mechanisms of action with immunopotentiators, immunomodulators, immunoadjuvants and other pharmacological agents active on cells participating in immune or allergic responses.
• Pharmacological compounds, microbial products and toxicological agents that affect the lymphoid system, and their mechanisms of action.
• Agents that activate genes or modify transcription and translation within the immune response.
• Substances activated, generated, or released through immunologic or related pathways that are pharmacologically active.
• Production, function and regulation of cytokines and their receptors.
• Classical pharmacological studies on the effects of chemokines and bioactive factors released during immunological reactions.
