ABSTRACT Laetiporus sp. is recognized as a fungal species traditionally used for medicinal purposes. This study investigated the in-vitro effects of solid-state fermented Laetiporussulphureus ethanol extracts (LSE) for their immunomodulatory potential. Bioactive levels detected in the LSE on different days throughout the fermentation period revealed that the 12th day was the most efficient, with 7.19 ± 0.66 GAE/g DM crude phenolic content, 2.71 ± 0.03 UAE/g DM crude triterpenoid content, 12.93 ± 0.88 GCE/g DM crude polysaccharides, and 96.44 ± 0.2 mg/g DM ergosterol content. In-vitroLSE tests on chPBMC showed no cytotoxicity within a range of 0.05-1 mg/mL, but LPS-inhibited cell viability was improved, as well as LPS-induced nitric oxide (NO) production and mRNA levels of nuclear factor kappa B (NFκB), Toll-like receptor 4 (TLR4), inducible nitric oxide synthase (iNOS), and interleukin (IL)-1βwere attenuated Furthermore, the direct application of LSE on chPBMC showed a small but not significant increase in NFκB, TLR4, and iNOS mRNA expression compared with the control group. These results indicate the potential of LSE to modulate LPS-triggered inflammation processes involving TLR4 and NFκB mediation. However, further experiments are required to determine the specific pathway.
