Abstract

T cell immunoglobulin and mucin domain–containing 3 (Tim-3) is an inhibitory receptor that is expressed on exhausted T cells during infection with HIV-1 and hepatitis C virus. By contrast, Tim-3 expression and function are defective in multiple human autoimmune diseases. However, the molecular mechanisms modulating Tim-3 function are not well understood. Here we show that human leukocyte antigen B (HLA-B)-associated transcript 3 (Bat3) binds to, and represses the function of, Tim-3. Bat3 protects T helper type 1 (TH1) cells from galectin-9–mediated cell death and promotes both proliferation and proinflammatory cytokine production. Bat3-deficient T cells have elevated expression of exhaustion-associated molecules such as Tim-3, Lag3, Prdm1 and Pbx3, and Bat3 knockdown in myelin-antigen–specific CD4+ T cells markedly inhibits the development of experimental autoimmune encephalomyelitis while promoting the expansion of a dysfunctional Tim-3hi, interferon-γ (IFN-γ)loCD4+ cell population. Furthermore, expression of Bat3 is reduced in exhausted Tim-3+ T cells from mouse tumors and HIV-1–infected individuals. These data indicate that Bat3 acts as an inhibitor of Tim-3–dependent exhaustion and cell death. Bat3 may thus represent a viable therapeutic target in autoimmune disorders, chronic infections and cancers.

  • Bat3 localization at the Tim-3 cytoplasmic tail allows continued T cell proliferation and IFNγ production, an effect lost in Bat3-deficient cells and upon Tim-3 binding to galectin-9.

    “Bat3 localization at this protein region allows T cells continued proliferation and IFNγ production, an effect that was lost on Bat3 deficient cells and upon Tim-3 binding to galectin-9.”
  • Bat3 modulates Tim-3 function on T cells by interacting with the Tim-3 cytoplasmic tail.

    “it has been postulated that the human leukocyte antigen (HLA)-B-associated transcript 3 (Bat3) modulates Tim-3 function on T cells by interacting with Tim-3 cytoplasmic tail [66].”
  • Release of BAT3 suggests that FYN tyrosine-protein kinase links with the TIM-3 cytoplasmic tail to generate inhibitory signaling that causes anergy of T cells by activating PAG1, prompting recruitment of CSK, leading to phosphorylating LCK and suppressing T cells.

    “Release of BAT3 suggests that FYN tyrosine‐protein kinase links with the TIM‐3 cytoplasmic tail to generate inhibitory signaling that causes anergy of T cells by activating the transmembrane protein phosphoprotein membrane anchor with glycosphingolipid microdomains 1 (PAG1). This prompts the recruitment of tyrosine kinase (CSK), leading to phosphorylating LCK and suppressing T cells [308, 312].”
  • Tyrosine kinase FYN and human leukocyte antigen B (HLA-B)-associated transcript 3 (BAT3) were suggested to inhibit the cytoplasmic tail of TIM-3 signaling.

    “Nevertheless, tyrosine kinase FYN and human leukocyte antigen B (HLA‐B)‐associated transcript 3 (BAT3) were suggested to inhibit the cytoplasmic tail of TIM‐3 signaling [307, 308, 309].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
