Despite efforts to develop novel treatment strategies, refractory and relapsing sarcoma, and high-risk neuroblastoma continue to have poor prognoses and limited overall survival. Monocyte-derived dendritic cell (DC)-based anti-cancer immunotherapy represents a promising treatment modality in these
LMPAB is a linear beta-(1-3)-glucan we isolated from polysaccharide extract of Agaricus blazei Murill (AbM). Effects of LMPAB on splenic natural killer (NK) cell activity, splenocyte proliferation, index of spleen and thymus, IFN-gamma expression in spleen and the concentration of IL-12, IL-18 and
K3/MIR1 and K5/MIR2 of Kaposi's sarcoma-associated herpesvirus (KSHV) are viral members of the membrane-associated RING-CH (MARCH) ubiquitin ligase family and contribute to viral immune evasion by directing the conjugation of ubiquitin to immunostimulatory transmembrane proteins. In a quantitative
The antitumor effect of peroral treatment with coumarin and its main metabolite in humans 7-hydroxycoumarin (7-OHC) against Sarcoma 180 in mice was studied. Both agents inhibited tumor growth and increased survival time of tumor-bearing animals. The antitumor effect was better when coumarins were
BACKGROUND
Recombinant human Interleukin-2 (IL-2) has been effective at inducing measurable antitumor responses in adults with renal cell carcinoma and melanoma. It also is being tested as adjuvant therapy for patients with acute myeloid leukemia after autologous bone marrow
Interleukin-2 (IL-2) transgenic Ewing sarcoma cells can induce tumor specific T and NK cell responses and reduce tumor growth in vivo and in vitro. Nevertheless, the efficiency of this stimulation is not high enough to inhibit tumor growth completely. In addition to recognition of the cognate
The success of cancer vaccines is limited as most of them induce corrupted CD8+ T cell memory populations. We reported earlier that a natural immunomodulator, neem leaf glycoprotein (NLGP), therapeutically restricts tumor growth in a CD8+ T cell-dependent manner. Here, our objective is to study
During physiological stimulation of resting T-cells, at least two activation signals by antigen presenting cells are required. Besides the first antigen-specific signal, the second costimulatory signal involves CD80 and CD86 expressed by the antigen presenting cell. These costimulatory molecules
AIDS-related Kaposi's sarcoma (KS) represents a complex interaction of host and viral factors. There are a number of fundamental questions surrounding the interplay between the disparate factors that can contribute to the pathogenesis and pathophysiology of this disease. Targets such as the
BACKGROUND
Desmoplastic small round cell tumor (DSRCT) and synovial sarcoma are rare tumors with dismal outcomes requiring new therapeutic strategies. Immunotherapies have shown promise in several cancer types, but have not been evaluated in DSRCT and synovial sarcoma. Because the immune
In mice killed Rothia dentocariosa cells in doses of about 1.5 mg dry weight activated anti-infection immunity to Listeria antigens and anti-tumour immunity to the ascitic form of mouse sarcoma S-180. Their probable target site is the macrophage. The Rothia-activated macrophages in human gingiva may
CD34(+) progenitor cells carrying human herpesvirus-8, Kaposi's sarcoma-associated herpesvirus (HHV-8/KSHV), have been described in the peripheral blood of AIDS patients suffering from Kaposi's sarcoma (KS). In this study, we investigated the influence of HHV-8 on the differentiation of CD34(+)
Many host factors contribute to the death of cells shed from cancers and with many immunogenic tumors immune control is decisive in determining the incidence of metastasis. Although an aromatic analogue of retinoic acid did not affect the growth of nonimmunogenic carcinomas or sarcomas it slowed the
Scolopendra subspinipes mutilans L. Koch has been used for cancer treatment in traditional Chinese medicine for hundreds of years. In this study, the effects of a polysaccharide-protein complex from Scolopendra subspinipes mutilans L. Koch (SPPC) on the tumor growth and immune function were assessed
The interferons (IFNs) were identified as novel, endogenous antiviral agents in 1957. Shortly thereafter, antiproliferative and immunostimulatory activities were identified for these compounds. Based on these observations, partially purified IFNs entered clinical trials in the 1970s and recombinant
