Spatiotemporal Noise Triggering Infiltrative Tumor Growth under Immune Surveillance
A spatiotemporal noise is assumed to reflect the environmental fluctuation in a spatially extended tumor system. We introduce firstly the structure factor to reveal the invasive tumor growth quantitatively. The homogenous environment can lead to an expansive growth of the tumor cells, while the inhomogenous environment underlies an infiltrative growth. The different responses of above two cases...
متن کاملTumor escape from immune surveillance.
The bases for an efficient anti-tumor immune response begin to be better defined. Nonetheless, neoplastic cells develop various strategies to escape immune surveillance, which are discussed here in order to better design the therapeutic possibilities of immune manipulation. The absence of specific tumor antigen as well as the weak expression of major histocompatibility complex (MHC) molecules h...
متن کاملNK cell heparanase controls tumor invasion and immune surveillance.
NK cells are highly efficient at preventing cancer metastasis but are infrequently found in the core of primary tumors. Here, have we demonstrated that freshly isolated mouse and human NK cells express low levels of the endo-β-D-glucuronidase heparanase that increase upon NK cell activation. Heparanase deficiency did not affect development, differentiation, or tissue localization of NK cells un...
متن کاملSTAT1 Ser727 – key regulator for NK cell-mediated cytotoxicity and tumor surveillance
The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling cascade plays an important role in hematopoiesis. A constitutive activation of this pathway is found in a broad variety of diverse human and murine leukemias and lymphomas. Whereas STAT3 and STAT5 accelerate and initiate tumor formation, STAT1 is generally considered a tumor suppressor. As shown by Kovacic et...
متن کاملA Brief Introduction: from Immune Surveillance to Tumor-immune Escape
Los tumores deben evadir la respuesta inmunológica para ser clínicamente detectables en el paciente. A estos fines, las células cancerosas han desarrollado múltiples estrategias para eludir el ataque inmunológico. Estos mecanismos conspiran en estadíos avanzados de un tumor limitando la habilidad del sistema inmune para inhibir el crecimiento tumoral y la efectividad de estrategias de inmunoter...
