Abstract

Tyro3, Axl and Mertk are members of the TAM family of tyrosine kinase receptors. TAMs are activated by two structurally homologous ligands GAS6 and PROS1 . TAM receptors and ligands are widely distributed and often co-expressed in the same cells allowing diverse functions across many systems including the immune , reproductive, vascular, and the developing as well as adult nervous systems . This review will focus specifically on TAM signaling in the nervous system, highlighting the essential roles this pathway fulfills in maintaining cell survival and homeostasis , cellular functions such as phagocytosis , immunity and tissue repair. Dysfunctional TAM signaling can cause complications in development, disruptions in homeostasis which can rouse autoimmunity, neuroinflammation and neurodegeneration . The development of therapeutics modulating TAM activities in the nervous system has great prospects, however, foremost we need a complete understanding of TAM signaling pathways.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • PROS1 acts as an anti-inflammatory mediator by activating TAM (TYRO3, AXL, and MERTK) receptors, facilitating the phagocytic clearance of apoptotic cells and dampening inflammation.

    “PROS1 acts as an anti‐inflammatory mediator by activating TAM (TYRO3, AXL, and MERTK) receptors, facilitating the phagocytic clearance of apoptotic cells and dampening inflammation. 48”

    From Unique transcriptomic alterations in 5XFAD;PS19 mouse model identify glial lipid dysregulation and coordinated microglial–oligodendrocyte responses (2026) · cites this paper as [48]

    The neuroimmune-interface section says PROS1 helps bridge apoptotic cells to phagocytes, promoting their clearance and anti-inflammatory signaling. But the receptors-and-ligands section explicitly says PROS1 activates TYRO3 and MERTK, not AXL; the claim incorrectly includes AXL among the receptors PROS1 activates.

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.
