  • Title: Release of soluble tumor necrosis factor receptors from polymorphonuclear cells of breast cancer patients.
    Author: Jabłońska E, Pietruska Z.
    Journal: Arch Immunol Ther Exp (Warsz); 1997; 45(5-6):449-53. PubMed ID: 9437501.
    Abstract:
    The release of soluble tumor necrosis factor receptors (sTNF-Rs): soluble tumor necrosis factor receptor I (sTNF-RI) and soluble tumor necrosis factor receptor II (sTNF-RII) by polymorphonuclear cells (PMNs) derived from patients with breast cancer were measured. Serum levels of sTNF-RII and sTNF-RII in patients group were also determined. Significantly higher values of sTNF-RI and sTNF-RII released by PMNs of patients were observed than those in the healthy subjects. There was no significant differences in the serum levels of sTNF-RI and sTNF-RII between breast cancer patients and healthy control. Presented study demostrate that the tumor bearing state, involving breast cancer, may induce an altered soluble cytokine receptors release from the peripheral blood PMNs characterized by increased concentrations of sTNF-RI and sTNF-RII in the culture supernatants of these cells in vitro.
