The aim of this study was to investigate the immunomodulatory effects of Spirulina platensis (S.platensis) by measuring the levels of serum interleukin (IL)-4, IL-10, IL-17, tumor necrosis factor(TNF)-α and interferon (IFN)-|γ| in mice suffered from systemic candidiasis and breast cancer. Theaqueous extract of S. platensis was selected for this study. Balb/C female mice were inoculated withCand...

We have prepared a construct (designated CATTNF) in which the mouse TNF (cachectin) coding sequence is replaced by a sequence encoding chloramphenicol acetyltransferase (CAT), with preservation of the TNF promoter and 3'-untranslated sequences known to be important in the regulation of gene expression. When activated by LPS, permanently transfected RAW 264.7 (mouse macrophage) cells synthesize ...

Treatment of sensitive human myosarcoma cells (KYM-S) with exogenous tumor necrosis factor (r-TNF) resulted in the production of TNF by the cells. The newly synthesized cellular TNF was identified immunologically on Western blots and as a single 1.8-kilobase band on Northern blots. TNF synthesis began within 2 h of administration of the exogenous TNF in a dose-dependent manner. r-TNF also induc...

After i.v. inoculation with Rhodococcus aurantiacus, wild-type (WT) mice develop nonnecrotic, epithelioid granulomas. Because a high level of TNF-alpha is observed during the initial phase postinfection, we examined the extent to which TNF-alpha contributes to granulomatous inflammation using TNF-alpha gene-deficient (TNF-alpha(-/-)) mice. Despite a lack of R. aurantiacus proliferation, TNF-alp...

Maresin-1 is a derivative of omega-3 fatty acids and show anti-inflammatory effect in cutaneous inflammatory diseases, such as psoriasis. On the contrary, these actions might unbeneficial effects inflammatory-required wound healing. In this study, we investigated maresin-1 on healing detailed molecular mechanisms. Topical was daily applied wounded mouse skinin vivo, influence evaluated. The sig...

Ligands of the tumor necrosis factor superfamily (TNFSF) (4-1BBL, APRIL, BAFF, CD27L, CD30L, CD40L, EDA1, EDA2, FasL, GITRL, LIGHT, lymphotoxin alpha, lymphotoxin alphabeta, OX40L, RANKL, TL1A, TNF, TWEAK, and TRAIL) bind members of the TNF receptor superfamily (TNFRSF). A comprehensive survey of ligand-receptor interactions was performed using a flow cytometry-based assay. All ligands engaged ...

It is well-documented that alcohol drinking together with hepatitis viral infection accelerates liver injury; however the underlying mechanisms remain unknown. In this paper, we demonstrated that primary hepatocytes from transgenic mice overexpressing hepatitis B virus X protein (HBX) were more susceptible to ethanol- and TNF-alpha-induced apoptotic killing. Compared to normal control mouse hep...

An assay was developed to detect the cytotoxic effects of cytokines on rat pancreatic islet cells in monolayer culture. Cell lysis was detected by a 51Cr-release assay after 4 days of incubation with various cytokines. When tested alone, murine (rat and mouse) interferon-gamma (mIFN-gamma) produced a small dose-dependent lysis of islet cells; human IFN-gamma, mouse IFN-alpha/beta, interleukins ...

A2B adenosine receptors are present in a wide spectrum of tissues, especially on cells the immune system. Since these particular have lowest, all receptor subtypes, affinity for they believed to play special role immunological processes associated with elevated levels such as inflammation. The aim this preliminary study was determine potential anti-inflammatory properties compound PSB-603, pote...
