“…Disruption of the BBB has been shown to be associated with neuroinflammation following ischemic injury,32 and hemorrhagic transformation has been reported as a maker of BBB breakdown 33. The ligand for ST2, IL‐33, is hypothesized to serve as an acute inflammatory signaling molecule that participates in maintaining barrier function and integrity 34. Isoforms of ST2 and IL‐33 are highly expressed in the brain and spinal cord, suggesting that IL‐33/ST2 may function directly in the central nervous system 12.…”

Objective ST2 is a member of the toll‐like receptor superfamily that can alter inflammatory signaling of helper T‐cells. We investigated whether soluble ST2 (sST2) could independently predict outcome and hemorrhagic transformation (HT) in the setting of stroke.MethodsWe measured sST2 in patients enrolled in the Specialized Program of Translational Research in Acute Stroke (SPOTRIAS) network biomarker study. 646 patients had plasma samples collected at the time of hospital admission and 210 patients had a second sample collected 48 h after stroke onset. Functional outcome was assessed using the modified Rankin Scale (mRS), with good and poor outcomes defined as mRS 0‐2 and 3‐6, respectively. HT was classified using ECASS criteria. The relationships between sST2, outcome, and HT were evaluated using multivariable logistic regression, Kaplan–Meier survival analysis and receiver operating characteristic curves.Results646 patients were included in the analysis (mean age 69 years; 44% women), with a median NIHSS of 5 [IQR: 2–12]. The median sST2 level on hospital admission was 35.0 ng/mL [IQR: 25.7–49.8 ng/mL] and at 48 h it was 37.4 ng/mL [IQR 27.9–55.6 ng/mL]. sST2 was independently associated with poor outcome (OR: 2.77, 95% CI: 1.54–5.06; P = 0.003) and mortality (OR: 3.56, 95% CI: 1.58–8.38, P = 0.001) after multivariable adjustment. Plasma sST2 was also associated with hemorrhagic transformation after adjustment for traditional risk factors (OR: 5.58, 95% CI: 1.40–37.44, P = 0.039).InterpretationSoluble ST2 may serve as a prognostic biomarker for outcome and hemorrhagic transformation in patients with acute stroke. ST2 may link neuroinflammation and secondary injury after stroke.

“…IL-2 is a T cell-differentiating cytokine and improves the cytolytic activities of cytotoxic T lymphocytes and natural killer (NK) cells (23). Meanwhile, IL-4 serves a key role by stimulating the differentiation of naive T cells (Th0 cells) to Th2 cells (24).…”

Effect of Coriolus versicolor glucan on the stimulation of cytokine production in sarcoma-180-bearing mice

Abstract. Coriolus versicolor (CV) contains high levels of bioactive compounds, including the glucan (1→6)-α-D-glucopyranosyl. However, there is a lack of data regarding the potential effect of this CV glucan (CVG) on the stimulation of cytokine production. The present study evaluated the effect of CVG on the stimulation of cytokine production in sarcoma-180-bearing mice. Mice were treated with three doses of CVG (40, 100 or 200 mg/kg body weight) for nine days, after which serum levels of cytokines, namely interleukin (IL)-2, -4, -6, -10, -17A and interferon (IFN)-α and -γ, were investigated by ELISA. CVG significantly promoted the secretion of IL-2, -4, -6, -10, -17A and IFN-α and -γ at the doses of 100 (P<0.05) and 200 (P<0.01) mg/kg, but not at 40 mg/kg (P>0.05), when compared with cyclophosphamide treatment, as a positive control. Additionally, cytokine production associated with T helper (Th)2 and Th17 cells was enhanced compared with that of Th1 cytokines, and the immunomodulatory function of CVG appeared to be IL-10-dependent. These results demonstrate that CVG may stimulate the production of cytokines and serve as a Th2/IL-10-dependent immunomodulator, and thus has promise in supporting cancer therapies.

IL-33 delays metastatic peritoneal cancer progression inducing an allergic microenvironment

et al. 2018

Ovarian cancer is frequently diagnosed as peritoneal carcinomatosis. Unlike other tumor locations, the peritoneal cavity is commonly exposed to gut-breaching and ascending genital microorganisms and has a unique immune environment. IL-33 is a local cytokine that can activate innate and adaptive immunity. We studied the effectiveness of local IL-33 delivery in the treatment of cancer that has metastasized to the peritoneal cavity. Direct peritoneal administration of IL-33 delayed the progression of metastatic peritoneal cancer. Prolongation in survival was not associated with a direct effect of IL-33 on tumor cells, but with major changes in the immune microenvironment of the tumor. IL-33 promoted a significant increase in the leukocyte compartment of the tumor immunoenvironment and an allergic cytokine profile. We observed a substantial increase in the number of activated CD4+ T-cells accompanied by peritoneal eosinophil infiltration, B-cell activation and activation of peritoneal macrophages which displayed tumoricidal capacity. Depletion of CD4+ cells, eosinophils or macrophages reduced the anti-tumor effects of IL-33 but none of these alone were sufficient to completely abrogate its positive benefit. In conclusion, local administration of IL-33 generates an allergic tumor environment resulting in a novel approach for treatment of metastatic peritoneal malignancies, such as advanced ovarian cancer.
