Antigens of Bordetella pertussis.III. The Protective Antigen
SummaryA method of preparing extracts from Bordetella pertussis with high protective and histamine sensitizing activity is described. From these extracts, starch block electrophoresis yielded active purified fractions which not only protected mice against intracerebral challenge with living B. pertussis cells but also sensitized mice to histamine. From

Signaling via interleukin-4, receptor alpha chain is required for successful vaccination against schistosomiasis in BALB/c mice [PDF]
Radiation-attenuated (RA) schistosome larvae are potent stimulators of innate immune responses at the skin site of exposure (pinna) that are likely to be important factors in the development of Th1-mediated protective immunity.

Deletion of parasite immune modulatory sequences combined with immune activating signals enhances vaccine mediated protection against filarial nematodes [PDF]
<p>Background: Filarial nematodes are tissue-dwelling parasites that can be killed by Th2-driven immune effectors, but that have evolved to withstand immune attack and establish chronic infections by suppressing host immunity. As a consequence, the

Evaluation of Crude Anthrax Protective Antigen as an Adjutant For Brucella Abortus Vaccine In Mice [PDF]
Anthrax crude protective antigen (PA) was used in this study as an adjutant with Brucella abortus S19 strain vaccine in a ratio of 1:1 to immunize mice in dose of 0.1 ml s/c in order to decrease side effects of S19 vaccine and also to enhance its ...

Recombinant HSA-CMG2 Is a Promising Anthrax Toxin Inhibitor
Anthrax toxin is the major virulence factor produced by Bacillus anthracis. Protective antigen (PA) is the key component of the toxin and has been confirmed as the main target for the development of toxin inhibitors.

Why is a protective antigen protective?
One of the major challenges in vaccine development is the identification of microbial components that give rise to a protective immune response. Over the last decade, genome and proteome-based methods have proven successful in discovering new vaccine candidates for many pathogens through the selection of secreted or surface-exposed protein antigens and

Yersinia Outer Membrane Vesicles as Potential Vaccine Candidates in Protecting against Plague
Despite the relatively low incidence of plague, its etiological agent, Yersinia pestis, is an exceptional epidemic danger due to the high infectivity and mortality of this infectious disease. Reports on the isolation of drug-resistant Y.
