Summary
[edit]DescriptionMaking of a DNA vaccine.jpg |
English: DNA vaccines are composed of a small, circular piece of DNA — called a DNA plasmid — that contains genes that code for proteins of a pathogen. When the vaccine is injected into the host, the inner machinery of the host cells “reads” the DNA and converts it into proteins from the pathogen. Recognizing that the proteins are foreign, the cells display them on their surface to alert the body’s immune system — both helper T cells, which spur the production of antibodies, and killer T cells, which kill infected cells outright.

This biology image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}} .
It is recommended to name the SVG file “Making of a DNA vaccine.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
This biology image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans. If this image is a diagram or other image suitable for vectorisation, please tag this image with {{Convert to SVG}} instead of {{BadJPEG}}. If not suitable for vectorisation, use {{Convert to PNG}}.
