The prostatic fluid of two patients with Escherichia coli bacterial prostatitis was analyzed for evidence of a local immune response to bacterial infection. A solid-phase radioimmunoassay was modified to measure the immunoglobulin (Ig)A and IgG antigen-specific antibody responses to infecting bacteria in serum and prostatic fluid from patient. Formalin-fixed whole E. coli were used as antigen. ...
In recent years, the microbiome has been recognized as a key regulator of immune responses. Evidence suggests that changes in the microbiome can lead to chronic disease and even exacerbation of the disease. Impairment of innate immunity resulting from microbial incompatibility may worsen host susceptibility to infection and exacerbate chronic lung diseases. Specific microbes play a key role in ...
Although the systemic and local immune response to the O antigen of Escherichia coli has been well characterized, little information is available on the immune response to K anigen. Experimental hematogenous pyelonephritis was produced with Escherichia coli 06 K13 H1 and the serum and local (intrarenal) antibody response to O and K antigens was determined with the enzyme-linked immunosorbent as...
Background: This study evaluated the effects of the maternal immune system stimulation or suppression during the pregnancy on the development of the neonate’s immune system.Methods: A total of 20 female rats were divided into four groups. The groups were treated using Leishmania major, Salmonella typhimurium, Tacrolimus, and sterilized normal saline. The animals were mated after 3-time tr...
Cancer treatment is one of the main fields in basic and clinical research. Immunotherapy or using immune response is considered as one of the most important and effective complementary approaches in cancer therapy after surgery, chemotherapy and radiotherapy. In recent years many clinical trials have investigated this approach. The complications involved in immune response against a tumor calls...
T lymphocytes have been characterized to different subsets such as cytotoxic T, Thelper1 (Th1), Th2, Th3, Th9, Th17, and regulatory T cells. Each of these subsets have specific function which distinct them from other lymphocytes. Regulatory T lymphocytes are effective cells in immune system that play an important role in cancers, autoimmune and infectious diseases. Two main subsets of regulator...
Backgrounds: Most of the hepatitis C virus (HCV) infections elicit poor immune responses and 75% to 85% of cases become chronic therefore, the development of an effective vaccine against HCV is of paramount importance. In this study, we aimed to evaluate co-administration of HCV non-Structural Protein 2 and IL-12 DNA vaccines in C57BL/6 mice. Methods: A plasmid encoding full-length HCV NS2 prot...
Effect of different levels of date waste were studied on performance and immune responses of 240 Ross 308 broiler chicks in a completely randomized design with 5 treatments and 4 replicates and 12 birds in each replicate. The whole date waste were analyzed for chemical compositions and gradual levels of 0 (control), 5, 10, 15 and 20 percent of that were included into the diets which fed broiler...
Concern about the effects of environmental contaminants on immune function in both humans and wildlife is growing and practically nothing is known about this impact on terrestrial invertebrates, even though they are known to easily accumulate pollutants. We studied the effect of industrial heavy metal contamination on immune defense of a free-living wood ant (Formica aquilonia). To find out whe...
