ONLINE: 26 October 2007 Abstract Although animals can be immunized against the growth of some tumor implants, most of the attempts to use immunotherapy to cause the regression of animal and human tumors once they have be established have been disappointing even when strongly immunogenic tumors were used as target.This paper, we demonstrate that the failure to achieve an efficient immunological treatment against an established strongly immunogenic murine fibrosaa was paralleled with viagra use uk viagra supplier the emergence of a state of immunological unresponsiveness (immunological eclipse) against tumor antigens observed when the tumor surpassed the critical size drug loss viagra weight of 500 mm3.Turn, the onset of the immunological eclipse was coincidental with the onset of a systemic inflammatory condition characterized by a high number of circulating and splenic polymorphonucleated neutrophils (PMN) displaying activation and Gr1+Mac1+ phenotype and an increasing serum concentration of the pro-inflammatory cytokines best herbal viagra TNF-, IL-1 and IL-6 cytokines and C-reactive protein (CRP) and serum A amyloid (SAA) phase acute proteins.Of tumor-bearing mice with a single low dose (0.Of the synthetic corticoid viagra information dexamethasone viagra seuss (DX) significantly reduced all the systemic inflammatory parameters and simultaneously reversed the immunological eclipse, as evidenced by the restoration of specific T-cell-dependent prescription free viagra coitant generic viagra online immunity, ability of spleen cells to transfer anti-tumor activity and recovery of T-cell signal transduction molecules.Other anti-inflammatory treatments by using indomethacin or dimeric TNF- receptor, also partially reversed the immunological eclipse although the effect was not as striking as that observed with DX.Reversion of the immunological eclipse was not enough on its free trial viagra own to inhibit the primary growing tumor.When we used the two-step strategy of inoculating DX to reverse the eclipse and then dendritic cells loaded with tumor antigens (DC) as an immunization booster, a significant inhibition of the growth of both established tumors and remnant tumor cells after excision of large established tumors was observed, despite the fact that the vaccination alone (DC) had no effect or even enhanced tumor growth in certain circumstances.Two-step strategy of tumor immunotherapy that we present is based on the rationale that it is necessary to eliminate or ameliorate the immunological eclipse as a precondition to allow an otherwise ineffective anti-tumor immunological therapy to have a chance to be successful.Keywords Tumor - Immunotherapy - Dendritic cells - Systemic inflammation RAГєL A.EMAIL: REFERENCES
