Inhibition of keratinocyte migration by lipopolysaccharide.

A critical process in cutaneous wound healing is reepithelialization by keratinocytes that closes the breach in the epidermis. Chronic wounds fail to reepithelialize despite the presence of activated and proliferative keratinocytes around the wound perimeter. This type of wound is generally colonized to a greater or lesser extent by bacteria.

Effects of oral vitamin C on monocyte: endothelial cell adhesion in healthy subjects.

Monocyte recruitment and retention in the vasculature is influenced by oxidative stress and is involved in cardiovascular disease (CVD). Individuals with low plasma ascorbate are at elevated risk of CVD. It is unknown whether vitamin C supplementation affects monocyte adhesion to endothelial cells (ECs) in healthy non-smokers.
