Neutrophil Chemotaxis Chasing a Bacteriu

<a class="link" rel="nofollow" href="http://www.FreeScienceLectures.com">http://www.FreeScienceLectures.com</a> Neutrophils are our body's first line of defense against bacterial infections.<br /><br />These cells can recognize certain chemicals and move to the source of these "chemoattractants" by migrating up the chemical concentration gradient or "toward the smell".<br /><br />The neutrophils were placed in a gradient of fMLP (n formyl methionine- leucine- phenylalanine), a peptide chain produced by some bacteria that is used by the neutrophils to find infecting organisms. The cells charge out like a "posse" after the bad guys.<br /><br />---<br />It's Never too Late to Study:<br /><a class="link" rel="nofollow" href="http://www.FreeScienceLectures.com">http://www.FreeScienceLectures.com</a> ---<br />Notice: This video is copyright by its respectful owners.<br />The website address on the video does not mean anything.<br />---
