Garlic (Allium sativum L.) is a species of the onion family (Alliaceae) widely used as food and folk medicine. The objective this study was to determine effects AGE (aged garlic extract) on pro-inflammatory genes relevant COVID-19. To aim, we treated bronchial epithelial IB3-1 cells with SARS-CoV-2 spike protein (S-protein) or COVID-19 BNT162b2 vaccine in absence presence AGE. results obtained demonstrated that potent inhibitor S-protein-induced expression IL-1β, IL-6 IL-8 genes. Bio-Plex analysis reduced release IL-8, which were highly induced by S-protein. No inhibition cells' growth, toxicity pro-apoptotic found AGE-treated cells. one major constituents (S-allyl cysteine, SAC) studied same experimental model systems. SAC able inhibit extracellular confirming S-allyl-cysteine responsible for inhibiting Docking experiments suggest possible mechanism action an interference activity Toll-like receptors (TLRs), particularly TLR4, thereby NF-κB- NF-κB-regulated genes, such These both deserve further efforts verify their SARS-CoV-2-infected

The coronavirus disease‑19 (COVID‑19) pandemic has been a very significant health issue in the period between 2020 and 2023, forcing research to characterize severe acute respiratory syndrome 2 (SARS‑CoV‑2) sequences develop novel therapeutic approaches. Interleukin‑6 (IL‑6) IL‑8 are considered targets for COVID‑19 emerging evidence suggested that microRNAs (miRNAs/miRs) serve key role regulating these genes. MiRNAs short, 19‑25 nucleotides length, non‑coding RNAs regulate gene expression at post‑transcriptional level through sequence‑selective recognition of 3'‑untranslated region (3'‑UTR) regulated mRNAs, eventually repressing translation, commonly, via mRNA degradation. For example, among several miRNAs involved regulation 'cytokine storm', miR‑93‑5p can inhibit by directly targeting 3'‑UTR mRNA. In addition, Toll‑like receptor‑4 (TLR4) interleukin‑1 receptor‑associated kinase 4 (IRAK4) expression, thus affecting nuclear factor‑κB (NF‑κB) pathway NF‑κB‑regulated genes, such as IL‑6, IL‑1β other hyper‑expressed genes during storm'. present study, results provided preliminary suggesting miR‑93‑5p‑based miRNA therapeutics could be combined with anti‑inflammatory aged garlic extract (AGE) more effectively expression. human bronchial epithelial IB3‑1 cell line was employed experimental model system. cells were stimulated BNT162b2 vaccine transfected pre‑miR‑93‑5p absence or presence AGE, verify inhibitory effects on BNT162b2‑induced gene. accumulation assessed RT‑qPCR; release protein determined Bio‑Plex assay. possible applications TLR4/NF‑κB agents (such AGE) treating pathologies hyperinflammatory state, COVID‑19, cystic fibrosis diseases, summarized.
