http://www.FreeScienceClips.com • • Neutrophils are our body's first line of defense against bacterial infections. • • 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 . • • 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. • • --- • Finest quality science clips: • http://www.FreeScienceClips.com • --- • Notice: This video is copyright by its respectful owners. • The website address on the video does not mean anything. • ---
