In this study, SLC38A6 was found to have increased expression in monocytes and macrophages during inflammatory responses, which correlated with higher numbers of these cells and elevated levels of proinflammatory cytokines (TNF-α and IL‑1β). Using both systemic and macrophage-specific knock-out models as well as pharmacological inhibition of the TLR4 pathway, the authors demonstrated that up-regulated SLC38A6 contributes to the enhancement of inflammatory cytokine expression and immune cell recruitment in pulmonary inflammatory conditions.\n\nHowever, the abstract does not mention FOXO6‑AS1, and therefore no functional details pertaining to FOXO6‑AS1 can be inferred from the given text. Further investigation in other sources would be needed to summarize the function of FOXO6‑AS1.\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Yizhao Peng, Weichao Chen, Fumeng Huang, et al.
