Specific targets of cellular immunity in human premalignancy are largely unknown. Monoclonal gammopathy of undetermined significance (MGUS) represents a precursor lesion to myeloma (MM). We show that antigenic targets of spontaneous immunity in MGUS differ from MM. MGUS patients frequently mount a humoral and cellular immune response against SOX2, a gene critical for self-renewal in embryonal s...
in order to evaluate the possible immunosuppressive effects of coccidial infection on cell mediated immunity (cmi) of broiler chickens, 640 ross male day old broiler chicks were randomly divided into 4 equal groups of 160 (each consist of 4 replicates of 40). the negative control group remained unchallenged, while the other three groups challenged with 3 different levels of high, medium and low...
Humoral and cell-mediated immune responses to varicella-zoster (V-Z) virus were assessed in patients during and after V-Z infections. Ongoing V-Z infections was associated with minimal cellular immunity but not necessarily with poor humoral immunity. Recovery from V-Z infection was associated with a vigorous cellular immune response. Cell-mediated immunity to V-Z virus was demonstrable for year...
restraint-induced stress (rs) increases histamine concentration in the brain. there is no previous report regarding the role of histamine receptors in immunomodulatory effect of rs. in the present study the role of brain histamine receptors on reduction of humoral and cellular immune function induced by rs was evaluated. for this purpose male wistar rats (200-250 g) were immunized with sheep re...
86 patients with lymphoma were evaluated prospectively for clinical and laboratory evidence of recurrent varicella-zoster, herpes simplex, and cytomegalovirus infections during the first 16 mo of treatment. Cellular immunity to the viral antigens was measured by in vitro lymphocyte transformation and interferon production. Antibody titers and nonspecific measures of cellular immunity, including...
Introduction: A large number of studies have proved a relationship between maligant mesothelioma and workers exposed to asbestos. The purpose of this study was to evaluate the degree of immunocompetence of the asbestos workers in comparison with non asbestos workers. Methods and materials: In this study 7 asbestotic patients, 73 workers exposed to asbestos and 59 controls from 2 Farsit fact...
The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...
Polymer particles are key materials in various biomedical applications, including drug delivery, cellular immunity, cell capture, biochip, etc. Droplets produced by microfluidics have been widely applied as templates for the fabrication of polymer with controllable sizes and narrow size distributions. Compared to smooth particles, those surface microstructures (e.g., tentacles, bubbles, wrinkle...
