From: Cancer immunometabolism: advent, challenges, and perspective
Metabolites | Target immune cell | Mediators | Effects on immunity | Outcomes | Refer to Refs. |
---|---|---|---|---|---|
Glu | Treg cell | mGlutR1 | Enhancement of Treg proliferation, activation, and immunosuppression | Pro-cancer | [9] |
FA | Treg cell | SREBP and FASN | SREBP combined with FASN promotes FA synthesis, which in turn promotes Treg maturation and drives immunosuppression | Pro-cancer | [11] |
Inhibition of FASN reduces fat accumulation in hepatocytes and directly suppresses immune cells and stellate cells | Anti-cancer | [122] | |||
CD8+ T cell | STAT3 | The leptin-STAT3 axis increases oxidation of FAs within CD8+ T cells in breast cancer | Pro-cancer | [81] | |
CD36 | CD36 mediated uptake of FA by CD8+ T cells, induced lipid peroxidation and ferroptosis, and led to reduced cytotoxic cytokine production | Pro-cancer | [161] | ||
B cell | CD37 | As essential membrane-localized inhibitor of FA metabolism, CD37 inhibits FATP1 (FA transporter) and subsequently leads to the inhibition of FA metabolism in aggressive B cell lymphomas | Anti-cancer | [162] | |
isoDCA | DCs and Treg cell | NR1H4; Foxp3 | isoDCA inhibits the transcriptional activity of NR1H4 in DCs and attenuate the immunostimulatory properties of DCs, which in turn induces Foxp3 expression and Treg cell generation | Anti-cancer | [16] |
Cholesterol | Neutrophil and CD8+ T cell | CXCR2 | Depletion of toxic γδ-T cells promotes breast cancer metastasis | Pro-cancer | [23] |
Tc9 cell | LXR | Cholesterol or its derivative oxysterols inhibited IL-9 expression by activating LXR Sumoylation-NF-κB signaling | Pro-cancer | [163] | |
Neutrophil | CXCR2 | Recruiting neutrophils to achieve a state of local TME inhibition | Pro-cancer | [164] | |
HIF1α | Promoting angiogenesis in pancreatic neuroendocrine tumors | Pro-cancer | [165] | ||
Leu | B cell | LARS2 | LARS2 knockdown or leucine blockade reduces LARS2-expressing B-cell subpopulations, which in turn inhibits immune escape in colorectal cancer | Anti-cancer | [44] |
Arg | CD8+ T cell | ARG1 | Extracellular ARG1could interact with cathepsin S and enhanced enzymatic activity at physiological pH, and NET-associated hARG1 suppresses T lymphocytes | Pro-cancer | [166] |
PGE2 | NK cell and cDC1 | may be XCL1 and CCL5 | Direct inhibition of NK cell survival and chemokine production that followed by downregulation of chemokine expression in cDC1 | Pro-cancer | [96] |
Lactate | Treg cell | MCT1 | Upregulation of lactate metabolic pathways to maintain immune response | Anti-cancer | [98] |
Cytotoxic T cell | SUCNR1 | Lactate reduces PC activity, succinate secretion and SUCNR1 activation, which inhibits autocrine signaling in cytotoxic T cells | Pro-cancer | [102] | |
αKG | Macrophage | Jmjd3; NF-κB | Coordinates M2 type activation of macrophages; Impairment of the pro-inflammatory response of M1 macrophages | Pro-cancer | [95] |
Glycerol | Memory CD8+ T cells | IL-7 | IL-7 signaling induces glycerol uptake to promote triacylglycerol synthesis and FAO, thus supporting the longevity of memory CD8+ T cells | Anti-cancer | [167] |
Trp | CD8+ T cell | I3A | L. reuteri promotes interferon-gamma-producing CD8+ T cells that thereby enhancing immune checkpoint inhibitor therapy | Anti-cancer | [60] |
Asn | CD8+ T cell | NRF2 | Asn restriction enhances the metabolic capacity and anti-tumor function of CD8+ T cells | Anti-cancer | [66] |
