The Uncommon Pathway of Campylobacter Jejuni

...wo decades that campylobacter can enter intestinal epithelial cells -- but until now no one could show how it was taken up or where it localized. That suggested it had evolved a special mechanism for uptake," said Watson. "Campylobacter seems to have found a special access to these cells and established its own...

Profiling of Cancer Genes May Lead to Earlier Detection Human Cancers

... them to gene expression profiles from normal lung epithelial cells. The researchers then examined the gene expression profiles of these various cell types before and after treatment with a drug that inhibits methylation. The researchers identified approximately 130 genes that may be methylated and thus sile...

Cellular Pathway Yields Potential New Weapon in Vaccine Arsenal

... that upregulate MHC class II upon inflammation -- epithelial cells of infected organs, for instance -- one could assume that they might actually use the autophagy pathway fairly frequently,” Münz says. Then, to test the pathway’s effectiveness, the researchers targeted an influenza antigen directly to autoph...

Study Compares LASIK and LASEK Eye Surgery

...times associated with the flap. In LASEK (laser epithelial keratomileusis), the surface cornea layer is treated with alcohol and then peeled back to permit reshaping of the underlying layer. It avoids all flap-related complications associated with LASIK, and has less postoperative pain and faster recovery th...

How Taste-buds Develop?

...ge papillae and taste buds. "Unlike most surface epithelial cells, taste buds have characteristics of neurons as well as skin. Like other types of epithelial cells they turn over and regenerate, but they also express chemoreceptors and make synapses with neu...

...sity in Tallahassee said, "We treated human breast epithelial cells with equal amounts of PhIP and DAS separately, and the two together, for periods ranging from three to 24 hours. PhIP induced expression of the cancer-causing enzyme at every stage, up to 40-fold, while DAS completely inhibited the PhIP enzyme ...

Immune Response Linked to “Ghost” Parasites and Severely Congested Sinuss

...vaders, such as bacteria, viruses or fungi. “The epithelial cells lining the nasal and sinus cavities play an important role as first responders of the immune system,” he says. “But when they are distracted fighting non-existent parasites, they cannot deal well with the very real microbes continuously coming ...

Study Provides Evidence That Obesity Leads To A More Aggressive Ovarian Cancer

...gnificant differences in the histological types of epithelial ovarian cancer depending on body mass index (BMI). They also explained that in women with advanced disease, a higher BMI might be associated with a reduced survival rates. Increasing evidence points to the importance of being obese (BMI greater tha...

Protective Intestinal Antibiotic Protein Discovered

...eria, the researchers were able to observe how the epithelial cells lining the intestine react to microbial invaders."We found that when the gut lining comes into contact with bacteria, it produces a protein that binds to sugars that are part of the bacterial outer surfaces," Dr. Hooper said. "Once bound, these...

New Test Could Detect Breast Cancer Early

"This may allow new, less intrusive, safer and much less expensive approaches for the early diagnosis of cancer, for distinguish...

Too Much of Air in the Lungs Results in VILI

Bates explains the difficulty of treating the injured lung this way: ‘Imagine you have two balloons which you fill by pu...

LL-37 Produced By the Body Found To Be Effective Against UTIs

... It was also proved that LL-37 was produced in the epithelial cells of the urinary tracts and the kidneys. The peptide was produced only if the body had prior exposure to the bacteria. The study results were published in the journal of Nature Medicine. In conclusion the author said that the study would prevent ...
