Background: The immunomodulatory effects of Korean mistletoe (Viscum album Coloratum) on the innate immune responses of eel (Anguilla japonica) were studied. Methods: Mistletoe, Freund’s complete adjuvant (FCA), or phosphate-buffered saline (PBS) as a control was injected into eel peritoneal cavities. Results: Nitroblue tetrazolium (NBT)-positive cells in the head kidney of eel were significant...
1. Many substances besides the specific broth filtrates of Besredka can be utilized as topical applications to protect guinea pigs from the effects of massive doses of staphylococcus given subcutaneously. (Plain broth, peptone 10 per cent, peptone 1 per cent, Liebig's meat extract, mustard plaster and normal horse serum.) 2. Where such protection occurs, no matter what the stimulus is, the loca...
Immunotherapeutic strategies including the blockade of programmed death 1 (PD-1) receptors hold promise for the treatment of various cancers including non-small cell lung carcinoma (NSCLC). Preclinical data suggest that pre-existing tumor immunity is important for disease regression upon checkpoint blockade-based therapies. However, the nature of antigen-specific T-cell responses that correlate...
A C57BL/6 mouse transgenic for human MUC1 (MUC1.Tg) was developed to evaluate MUC1-specific tumor immunity in an animal that expresses MUC1 as a normal self protein. Previous studies showed that MUC1.Tg mice, challenged with syngeneic tumors expressing MUC1 (B16.MUC1), developed progressively growing MUC1-positive tumors, whereas wild-type C57BL/6 (wt) mice developed MUC1-negative tumors at a s...
trichomoniasis, the most widespread sexually transmitted disease is caused by trichomonas vaginalis. this parasite is site specific for the genitourinary tract and recruitment of macrophages as well as polymorphonuclear nutrophils (pmn) to the site of infection is the first line of defense as a component of non-specific resistance and immunity. in this study, balb/c mice were infected with 10 i...
objective: the immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. materials and method: the essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. the essential oils were tested for hypersensitivity and hemagglutination reaction...
Innate lymphoid cells (ILCs) are key regulators of tissue homeostasis, inflammation, and immunity to infections. ILCs rapidly respond environmental cues such as cytokines, microbiota invading pathogens which regulate their function phenotype. Even though rare cells, they enriched at barrier surfaces the gastrointestinal (GI) tract, often critical host’s immune response eliminate pathogens. On o...
