background: tumor associated antigens can be viably used to enhance host immune response.objectives: the immunomodulatory effect of biogenic selenium nanoparticles (senps) was compared between treated and untreated mice with crude antigens of 4t1 cells.materials and methods: female inbred balb/c mice (60) were injected by cancinogenic 4t1 cells causing breast cancer. after 10 days, all tumor be...

UNLABELLED We used an embryonic-infection model system to show that MVMp, the prototypic minute virus of mice (MVM) serotype and a member of the genus Protoparvovirus, triggers a comprehensive innate immune response in the developing mouse embryo. Direct inoculation of the midtrimester embryo in utero with MVMp results in a widespread, productive infection. During a 96-h infection course, embry...

specific and non- specific cellular immune responses were studied in 20 amoebiasis cases and 10 controls. all the study cases and controls were indians living in varanasi, india. ten amoebic liver abscess cases were patients admitted to university hospital. ten non-invasive intestinal amoebiasis cases constituted the second study group. non-specific immune responses were studied using e-rosette...

The role of microRNAs (miRNAs) in regulating innate immune response to Candida albicans infection in Caenorhabditis elegans is still largely unclear. Using small RNA SOLiD deep sequencing technique, we profiled the miRNAs that were dysregulated by C. albicans infection. We identified 16 miRNAs that were up-regulated and 4 miRNAs that were down-regulated in nematodes infected with C. albicans. B...

Immunity is hypothesized to share limited resources with other physiological functions and may mediate life history trade-offs, for example between reproduction and survival. However, vertebrate immune defense is a complex system that consists of three components. To date, no study has assessed all of these components for the same animal model and within a given situation. Previous studies have...

BACKGROUND The role of the innate immune system in the pathogenesis of asthma is unclear. Activation of innate immune receptors in response to bacterial lipopolysaccharide, viral infection and particulate matter triggers a pre-programmed inflammatory response, which involves interleukin (IL)8 and neutrophil influx. The inflammatory response in asthma is heterogeneous. AIM To test the hypothes...

Multiple sclerosis is a demyelinating disease associated with an inflammatory immune response in the CNS. Theiler's murine encephalomyelitis virus (TMEV)-induced demyelinating disease is a relevant mouse model for the study of multiple sclerosis. TMEV infection of susceptible mice leads to a persistent virus infection of the CNS which contributes to development of demyelinating disease. We have...

The innate immune response provides our first line of defence against infection. Over the course of evolution, pathogens have evolved numerous strategies to either avoid activating or to limit the effectiveness of the innate immune system. The Kaposi's sarcoma-associated herpesvirus (KSHV) contains tegument proteins in the virion that contribute to immune evasion and aid the establishment of vi...

Leprosy control is achieved through a fine-tuning of TH1 and TH2 immune response pattern balance. Given the increasing epidemiological overlay of HIV and M. leprae infections, immune response in co-infected patients consists in an important contemporary issue. Here we describe for the first time the innate lymphoid cells compartment in peripheral blood of leprosy and HIV/M. leprae co-infected p...

The complexity of the immune responses is a major challenge in current virotherapy. This study incorporates the innate immune response into our basic model for virotherapy and investigates how the innate immunity affects the outcome of virotherapy. The viral therapeutic dynamics is largely determined by the viral burst size, relative innate immune killing rate, and relative innate immunity deca...
