The air-dried samples were sputtered with gold before imaging. The conclusion from these studies is that a cytokeratin, a protein that plays a structural role within cells, appears to protect the surface of the eye. The keratin peptides identified in the extract were synthesized, and their individual activities were studied. Why is it that this surface looks so healthy, most of the time? Figure 3.

When it comes to germ-busting power, the eyes have it, according to a discovery by UC Berkeley researchers that could lead to new, inexpensive antimicrobial drugs. Proteins in the eye can help keep pathogens at bay, finds a new UC Berkeley study. A team of UC Berkeley vision scientists has found that small fragments of keratin protein in the eye play a key role in warding off pathogens. The researchers also put synthetic versions of these keratin fragments to the test against an array of nasty pathogens. These synthetic molecules effectively zapped bacteria that can lead to flesh-eating disease and strep throat Streptococcus pyogenes, diarrhea Escherichia coli, staph infections Staphylococcus aureus and cystic fibrosis lung infections Pseudomonas aeruginosa. The findings, to be published in the October issue of the Journal of Clinical Investigation, could lead to a powerful new weapon in the battle against disease-causing invaders.
