White Blood Cell Chases Bacteria in real life

Edit: axxsmith informed me that it is from quote " It is a neutrophil chasing Staphylococcus aureus by David Rogers, Vanderbilt University

All credit goes to him.

Sorry to say I did not make this video. I found it on a website a few years ago and downloaded it. I could not find it again afterword and could not find it on youtube so I posted it up. If anyone knows who made it ill be glad to post that up for credit.

http://www.nucleusinc.com This 3D medical animation shows how antibodies stop harmful pathogens from attaching themselves to healthy cells in the blood stream. The animation begins by showing normal red and white blood cells flowing through the blood stream. Next, a single pathogen appears onscreen slowly moving toward its destination on the surface of a cell. The tubular extensions on the pathogen are surface proteins which attach to

corresponding surface proteins on a white blood cell, or leukocyte. As the animation continues, more pathogens continue to attach to the white blood cell, rendering it ineffective.

During the immune system response, Y-shaped antibodies begin attacking the pathogen, binding to its surface proteins as the pathogen attempts to anchor to the blood cell. The antibodies completely block the pathogen from attaching to the blood cell, "tagging" the pathogen so

that one of the immune system's leaner cells, a macrophage, appears onscreen to engulf and digest the pathogen.
