Lentinan, a natural β-glucan extracted from the shiitake mushroom (Lentinula edodes), acts as a non-specific immune enhancer[1]. Lentinan enhances immune responses by activating macrophages, dendritic cells, and natural killer cells, and by promoting the expression of pro-inflammatory cytokines such as TNF-α and IL-6[2]. Lentinan is commonly used in research related to anti-tumor, anti-inflammatory, and neuroprotective effects[3].
In vitro, pretreatment of bovine mammary epithelial cells with Lentinan (100μg/mL; 6h) abolished LPS-induced ROS, restored SOD/T-AOC, up-regulated Nrf2/HO-1, silenced NF-κB/MAPK, suppressed IL-1β/IL-6/TNF-α and blocked apoptosis without cytotoxicity[4]. Treatment of A549 lung cancer cells with Lentinan (100μM; 48h) reduced IL-6 and IL-1β levels, decreased caspase-1 activity, raised ROS, lowered GPx4, depolarized mitochondria and activated caspase-3/DNA damage[5].
In vivo, Lentinan (10mg/kg/day; i.p.; 5 days) reversed house dust mite(HDM)-induced airway eosinophilia, IL-4/5/13 overproduction, mucus hypersecretion and ZO-1 loss in HDM-sensitized C57BL/6 mice[6]. Lentinan (200mg/kg/day; p.o.; 14 days) reversed antibiotic-induced colitis in C57BL/6J mice, restored colonic ZO-1/Occludin expression, reduced TNF-α and IL-6 levels, suppressed NF-κB activation, elevated propionic and butyric acid concentrations, reduced Proteobacteria abundance, and enriched SCFA-producing S24-7, Lactobacillus and Allobaculum[7].

|
Cell lines |
A549 cells |
|
Preparation Method |
The A549 cells were cultured in DMEM (Dulbecco's Modified Eagle's Medium) medium supplemented with 4mM L-glutamine and 10% fetal bovine serum (FBS), 100Units/ml penicillin and 100μg/ml streptomycin. The cells were incubated at 37°C, 5% CO2, and 95% air. Prior to each experiment 3.0×105 or 2.0×104 cells were seeded in a 6-well plate or 96-well plate, respectively. Cells were treated with 100µM Lentinan for 48h. Then cytotoxicity was assessed using the CCK-8 assay. Cellular Reactive Oxygen Species Detection Assay Kit was used according to manufacturer to quantify the ROS production. GPx4 activity were measured by the NADPH-coupled assay, using hydrogen peroxide and phosphatidylcholine hydroperoxide as the substrate. The caspase-1 activity was recorded using YVAD-AFC substrate at 505nm. |

Animal models |
Female C57BL/6 mice |
|
Preparation Method |
Female C57BL/6 mice, aged between 6 to 8 weeks were anesthetized with isoflurane and intranasally administered 40μl of a 0.25mg/ml house dust mite(HDM) extract by Greer Laboratories on days 1-3 for sensitization. On days 8-12, they were intraperitoneally injected with Lentinan at dosages of 10mg/kg, 1 hour prior to HDM challenge. The control group received intranasal administration of PBS during sensitization and challenge. 48h after the last administration, mice were euthanized under anesthesia with avertin, and their organs were dissected for further Histopathological examination, qRT-PCR and Western blotting analysis. To collect the BALF, the trachea and lungs were flushed three times using 1ml of PBS. After centrifugation (300g, 10min, 4°C), the supernatant of BALF was harvested for further analysis. CellDrop® and flow cytometry were used for cell classifying and counting in BALF sediment. The presence of neutrophils was confirmed by their CD45+Ly6G+ immunophenotype, and eosinophils were identified through their CD45+ absence of Ly6G, CD11c, and presence of SiglecF. |
