UV-Induced Neutrophil Infiltration and Increased MMP Secretion in Photo Skin Aging

The primary mechanism of photo skin aging is mediated by UV induced reactive oxygen species (ROS). ROS damages biomacromolecules and function as intracellular signal to activate transcription factors AP-1 and NF-kB . AP-1 And NF-kB are known to regulate a … Continue reading

The Effect of UV-Induced Gene Activation On Photo Skin Aging

The primary mechanism of UV-induced skin aging is mediated by the generation and accumulation of free radicals including reactive oxygen species (ROS) and reactive nitrogen species (RNS). ROS or free radicals not only can damage proteins, DNA, cellular membrane and … Continue reading
