Ingia / Ingia

Prostaglandins (PGs) and leukotrienes (LTs) are produced in Mycobacterium tuberculosis (Mtb)-infected lungs and have immune suppressive and protective effects, respectively. Considering that both of these mediators are produced during mycobacterial infection, we investigated the specific and

Immunostimulatory properties of a novel adjuvant administered with inactivated influenza virus vaccine.

Ingia / Ingia

The immunopotentiating activity of a new delivery system was investigated comparatively to Alhydrogel adjuvant, as an antiviral inactivated vaccine after one injection. The efficiency of the new formulation (BioMed) was evaluated with an inactivated porcine strain of influenza (A/Sw/IN/1726/88 H1N1)

CD14+ CD34+ peripheral blood mononuclear cells migrate across endothelium and give rise to immunostimulatory dendritic cells.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We describe a subset of peripheral CD14+ cells, coexpressing the CD34 progenitor marker and able to migrate across endothelial cell monolayers. On culture with granulocyte-macrophage-CSF, this population differentiated into dendritic cells expressing CD83, CD80, HLA-DR(bright), CD86, and CD54. These

Short double-stranded RNA with immunostimulatory activity: sequence dependence.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Small interfering RNAs (siRNA) are able to activate the mammalian innate immune system depending on their structure, sequence, and method of delivery. The immunostimulatory activity of double-stranded RNA can be applied to antiviral and antitumor therapy. Here we identified a set of 19-bp RNA

Immunostimulatory capacity of DNA vaccine vectors in porcine PBMC: a specific role for CpG-motifs?

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

With the development of DNA vaccines in pigs, the possibility was investigated that the nature and the amount of certain CpG-motifs present on plasmid DNA might have an effect on their immunostimulatory capacity. A panel of three CpG-oligodeoxynucleotides (ODN) and three eukaryotic expression

Murine strain variation in the natural killer cell and proliferative responses to the immunostimulatory compound 7-allyl-8-oxoguanosine: role of cytokines.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

7-Allyl-8-oxoguanosine (loxoribine) is a di-substituted guanine ribonucleoside which has been shown previously to enhance murine NK activity, B lymphocyte proliferation, and antibody synthesis. In this study we examined the relationship among enhancement of NK activity, proliferation, and cytokine

In vitro immunogenic and immunostimulatory effects of zwitterionized 23-valent pneumococcal polysaccharide vaccine compared with nonzwitterionized vaccine.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

BACKGROUND It was hypothesized that the observed slight immunostimulatory effect of the 23-valent pneumococcal polysaccharide (pneumo-23) vaccine might be due to the presence of low levels of zwitterionic motifs. Therefore, it was hypothesized further that introducing zwitterionic motifs

Inhibition of RNA-dependent DNA polymerase of avian myeloblastosis virus by pyran copolymer.

Ingia / Ingia

PYRAN COPOLYMER, A KNOWN IMMUNOSTIMULATOR, WAS FOUND TO BE A POTENT INHIBITOR OF PURIFIED DNA POLYMERASE (DEOXYNUCLEOSIDETRIPHOSPHATE: DNA deoxynucleotidyltransferase; EC 2.7.7.7) isolated from avian myeloblastosis virus. Unlike other inhibitors, pyran showed unique features of inhibition. It

Honeybee apisimin and plant arabinogalactans in honey costimulate monocytes.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Here we determined whether immunostimulatory plant-derived arabinogalactan proteins (AGPs) and the honeybee-derived protein apisimin are present in varieties of New Zealand honey. Apisimin is a protein of unknown function secreted from the glands of honeybees into Royal Jelly, forming a complex with

Effect of Corynebacterium parvum, methanol-extraction residue of BCG, and levamisole on macrophage random migration, chemotaxis, and pinocytosis.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Three parameters of macrophage function: random migration, chemotaxis, and pinocytosis, were studied in the guinea pig after administration of Corynebacterium parvum, methanol-extraction residue of BCG, and levamisole (LMS), a synthetic anthelmintic. Macrophage migration studies were performed with

Influenza (H1N1)-ISCOMs enhance immune responses and protection in aged mice.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Aging is associated with a decline in immune function and the elderly are therefore more susceptible to infectious disease and less responsive to vaccination. Influenza antigens complexed as immunostimulatory complexes (ISCOMs) generate more potent protective immune responses compared with

Pectin isolated from white cabbage--structure and complement-fixing activity.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

This study was done to investigate whether white cabbage contained polysaccharides with immunostimulatory activity using the complement-fixing test as an indicator. The main polysaccharide isolated was of pectin nature. Methanolysis and (13)C-NMR showed that the polymers consisted of highly

Bacterial cell wall products increase monocyte HLA-DR and ICAM-1 without affecting lymphocyte CD18 expression.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Bacterial cell wall products such as lipopolysaccharide (LPS) and muramyl dipeptide (MDP) have the capacity to enhance immune responses to antigens. The expression of surface class II major histocompatibility antigens and the costimulatory receptors CD18 and CD54/ICAM-1 (intercellular adhesion

Reprogramming tumor-associated dendritic cells in vivo using miRNA mimetics triggers protective immunity against ovarian cancer.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Modulating the activity of miRNAs provides opportunities for novel cancer interventions. However, low bioavailability and poor cellular uptake are major challenges for delivering miRNA mimetics specifically to tumor cells. Here, we took advantage of the spontaneous enhanced endocytic activity of

Biological characterization of three novel variants of IFN-alpha 13 produced by human placental trophoblast.

Ingia / Ingia

Interferon (IFN)-alpha from the human placenta was cloned and expressed with the aim to study the antiviral, antiproliferative, and immunostimulatory activities. In the present study, we describe three previously unknown sequence variants of IFN-alpha 13 originating from the villous trophoblast. The
