Recombinant HcpA-EspA-Tir-Stx2B chimeric protein induces immunity against attachment and toxicity of Escherichia coli O157:H7.

Summary of "Recombinant HcpA-EspA-Tir-Stx2B chimeric protein induces immunity against attachment and toxicity of Escherichia coli O157:H7."

It is about 4 decades from the identification of Enterohemorrhagic Escherichia coli (EHEC) as a food-borne pathogen. There are many shreds of evidence that the bacteria are significant sources of intestinal infections and outbreaks even in developed countries. Developing an effective vaccine against O157 and non-O157 serotypes of EHEC is a good strategy to combat the bacteria. Raising antibody against main toxicity, adhering and colonizing apparatus of the bacteria using a multi-antigenic protein can be hopefully applicable.

Medical and Biotech [MESH] Definitions

A live vaccine containing attenuated poliovirus, types I, II, and III, grown in monkey kidney cell tissue culture, used for routine immunization of children against polio. This vaccine induces long-lasting intestinal and humoral immunity. Killed vaccine induces only humoral immunity. Oral poliovirus vaccine should not be administered to immunocompromised individuals or their household contacts. (Dorland, 28th ed)

Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

The GENETIC RECOMBINATION of the parts of two or more GENES resulting in a gene with different or additional regulatory regions, or a new chimeric gene product. ONCOGENE FUSION includes an ONCOGENE as at least one of the fusion partners and such gene fusions are often detected in neoplastic cells and are transcribed into ONCOGENE FUSION PROTEINS. ARTIFICIAL GENE FUSION is carried out in vitro by RECOMBINANT DNA technology.

The in vitro fusion of GENES by RECOMBINANT DNA techniques to analyze protein behavior or GENE EXPRESSION REGULATION, or to merge protein functions for specific medical or industrial uses.

A secretory proteinase inhibitory protein that was initially purified from human SKIN. It is found in a variety mucosal secretions and is present at high levels in SPUTUM. Elafin may play a role in the innate immunity (IMMUNITY, INNATE) response of the LUNG.
