background: neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. the aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type iv pilus biogenesis protein antige...
We have identified long-incubation viral agents that share epitopes with hepatitis B virus (HBV). During chimpanzee infectivity studies, these agents may be recognized in the liver since they possess complementary nucleic acid sequences with HBV DNA; the genomic size was found to be 3.2 kilobases, identical to that of HBV. Liver injury was produced and there was antigen expression in hepatocyte...
INTRODUCTION There seem to be no published data concerning the clinical impact of populations of hepatitis B virus (HBV) in the hepatic and extrahepatic compartments of HIV-infected people with severe acute hepatitis. CASE PRESENTATION A 26-year-old Caucasian man presenting to our hospital with clinical symptoms suggesting acute hepatitis was found to have an acute hepatitis B profile upon ad...
Abstract Background There is a decrease in vaccine-specific antibody to certain vaccine-preventable diseases in children after chemotherapy, but the frequency of non-immune patients is not clear. In the present case-control study, was taken under investigation protection level to Hepatitis B infection in children 6 months after completing chemotherapy. Materials and Methods In this study 6...
Mutational escape from the CTL response represents a major driving force for viral diversification in HIV-1-infected adults, but escape during infancy has not been described previously. We studied the immune response of perinatally infected children to an epitope (B57-TW10) that is targeted early during acute HIV-1 infection in adults expressing HLA-B57 and rapidly mutates under this selection ...
Some of the greatest beneficiaries of the revolutionary advances in biotechnology over the past 15 years have been producers of diagnostic reagents, especially for the cloning and expression of antigens, primarily of viral origin. Recombinant DNA technology provides methods for producing antigens for diagnostic assays that are more highly purified, more specific, and safer to produce than viral...
Adaptive immune responses associated with allergic reactions recognize antigens from a broad spectrum of plants and animals. Herein a meta-analysis was performed on allergy-related data from the immune epitope database (IEDB) to provide a current inventory and highlight knowledge gaps and areas for future work. The analysis identified over 4,500 allergy-related epitopes derived from 270 differe...
objective(s):brucellosis, especially caused by brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500,000 human cases reported annually. the commonly used live attenuated vaccine in ovine brucellosis prophylaxis is b. melitensis rev1. but due to different problems caused by the administration of this vaccine, a protective subunit vaccine against b. me...
successful clearance of hepatitis b virus (hbv) is a promising event in which host's immune system will attempt to get rid of the virus. the immunological events of hbsag seroclearance have attracted great attention in both natural history investigations and therapeutic trials. recent genome-wide association studies (gwas) has confirmed polymorphisms in the human leukocyte antigen (hla)-dp locu...
