| contents | Metabolic Profiling and In Vitro Assessment of the Immunomodulatory Effects of Hydrodistillation-Derived Extracts from the Fruticose Lichen (L.) Zopf. on Human Lymphocytes. Essadki, Yasser Casas-Rodríguez, Antonio Cascajosa-Lira, Antonio Diez-Quijada, Leticia Campos, Alexandre Vasconcelos, Vitor El Khalloufi, Fatima Oudra, Brahim Cameán, Ana M Jos, Angeles Lichens are complex symbiotic systems known for synthesizing diverse secondary metabolites with documented antimicrobial, antioxidant, and antiproliferative activities. The present study focused on , a species widely distributed across Moroccan habitats. Two hydrodistillation-derived extracts (HE1 and HE2) were analyzed through ultra-high-Performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) to characterize their metabolite composition, and their effects were evaluated on Jurkat cells, a representative human cell line of the immune system. As the results of the characterization, the main compounds identified were Caprolactam, N,N-Diethylaniline, Erucamide, and 4-Isopropylaniline. Cytotoxicity assessment revealed that both HE1 and HE2 decreased the viability of Jurkat cells in a concentration-dependent manner. The mean effective concentrations (EC) after 24 h of treatment were 53.79 ± 2.92 µg/mL for HE1 and 59.76 ± 2.01 µg/mL for HE2. Cell death mechanisms were further examined by flow cytometry, revealing that apoptosis predominated after 24 h of treatment, progressing mainly to late apoptotic stages after 48 h. In parallel, the expression levels of key cytokine genes, including IL-2, TNF-α, and IFN-γ, were quantified at the mRNA level to evaluate potential immunomodulatory effects. Up-regulation was observed in IL-2 after exposure to both extracts for 24 and 48 h, and in the case of IFN-γ after exposure to HE2 for 24 h; in contrast, HE1 and HE2 produced down-regulation in TNF-α at 24 h. These findings suggest that HE1 and HE2 have immunomodulatory activity in Jurkat cells. Further investigations are needed to elucidate the underlying mechanisms and to clarify how HE1 and HE2 influence immune responses in human systems. |
