PaR1 secreted by the type IX secretion system is a protective antigen of Riemerella anatipestifer [PDF]

Frontiers in Microbiology, 2023
Riemerella anatipestifer mainly infects domestic ducks, geese, turkeys, and other birds, and causes considerable economic losses to the global duck industry. Previous studies have shown that concentrated cell-free culture filtrates of R.

Recombinant full-length Bacillus Anthracis protective antigen and its 63 kDa form elicits protective response in formulation with addavax [PDF]

Frontiers in Immunology, 2023
IntroductionBacillus anthracis is the causative agent for the lethal disease anthrax, primarily affecting animals and humans in close contact with an infected host. The pathogenicity of B. anthracis is attributed to the secreted exotoxins and their outer

Impact of HLA Polymorphism on the Immune Response to Bacillus Anthracis Protective Antigen in Vaccination versus Natural Infection [PDF]

Vaccines, 2022
The causative agent of anthrax, Bacillus anthracis, evades the host immune response and establishes infection through the production of binary exotoxins composed of Protective Antigen (PA) and one of two subunits, lethal factor (LF) or edema factor (EF).

Two approaches for the stabilization of Bacillus anthracis recombinant protective antigen [PDF]

Human Vaccines & Immunotherapeutics, 2021
Anthrax is a zoonotic disease caused by the gram-positive spore-forming bacteria Bacillus anthracis. There is a need for safe, highly effective, long-term storage vaccine formulations for mass vaccination. However, the development of new subunit vaccines

Polysaccharide PCP-I isolated from Poria cocos enhances the immunogenicity and protection of an anthrax protective antigen-based vaccine [PDF]

Human Vaccines & Immunotherapeutics, 2020
Polysaccharides isolated from natural plants may represent a novel source of vaccine adjuvants. In this research, we focused on a natural plant polysaccharide, PCP-I, which is derived from Poria cocos, a Chinese traditional herbal medicine.

An escherichia coli vaccine co-expressing listeriolysin-O and tumour antigen in cancer immunotherapy and the mechanisms of immune regulation [PDF]

, 2009
PhDSome recombinant bacterial strains have been shown to be very efficient in experimental therapies against cancer in rodent models. Amongst them is an E. coli that expresses the Listeriolysin-O protein (LLO) and a model tumour antigen ovalbumin (OVA)

Characterization of immunoglobulin G antibodies to Plasmodium falciparum sporozoite surface antigen MB₂ in malaria exposed individuals [PDF]

, 2009
Background MB2 protein is a sporozoite surface antigen on the human malaria parasite Plasmodium falciparum. MB2 was identified by screening a P. falciparum sporozoite cDNA expression library using immune sera from a protected donor immunized via the ...

Avidity of influenza-specific memory CD8+ T-cell populations decays over time compromising antiviral immunity [PDF]

, 2012
Decline of cell-mediated immunity is often attributed to decaying T-cell numbers and their distribution in peripheral organs. This study examined the hypothesis that qualitative as well as quantitative changes contribute to the declining efficacy of CD8+
