changes, in skin immunity with age cellular level, genetic program and environmentally imposed damageAn in-depth look at cutting-edge research on the body's innate immune systemInnate immunity is the body's first line of protection against potential microbial, viral, and environmental attacks, and...
"As we age, the stiffness of our skin changes," explains Ashani Weeraratna, Ph.D., associate director for laboratory research at the Kimmel Cancer Center and professor of oncology at the Johns Hopkins University School of Medicine. "That not only has physical implications, but it also has s...
Dramatic changes occur in skin as a function of age, including changes in morphology, physiology, and mechanical properties. Changes in extracellular matrix molecules also occur, and these changes likely contrib-ute to the overall age-related changes in the physical properties of skin. The major pr...
5. Age-related changes in the distribution of skin with fat were smaller. Its percentage increased in the wings, legs and back, and decreased in the neck and breast. 6. Until the age of 7 weeks the percentage of bones was decreasing quickly in the legs and increasing in the neck and ...

changes in transcriptional processes across different organisms: nematodes, fruitflies, mice, rats and humans. The average transcriptional elongation speed (RNA polymerase II speed) increased with age in all five species. Along with these changes in elongation speed, we observed changes in splicing, ...
Previous studies of the age-related changes in interstitial collagens, have suggested that the proportion of type III collagen compared with type I decreases with age. In this study collagen concentration and the proportion of types were measured in heart, lung and skin of male Lewis rats aged ...
In contrast, strains derived from older women (n=20) had a mean value of 5.44+/-0.48 fmol of ERalpha per 10(6) cells. An age-related increase in ERalpha number was also observed in human skin-derived fibroblasts and directly in dermal biopsies from women not on hormone replacement ...
This research investigated the skin microbiome of a large cohort of Caucasian women across a broad age range (20‒70 years) at multiple skin sites, which in combination with aging-associated changes in host factors, provides a better understanding of how and why the skin microbiome changes with...
