Significance: Keratinocytes, a major cellular component of the epidermis, are responsible for restoring the epidermis after injury through a process termed epithelialization. This review will focus on the pivotal role of keratinocytes in epithelialization, including cellular processes and mechanisms of their regulation during re-epithelialization, ...
Stress-induced hormones can alter the inflammatory response to tissue injury; however, the precise mechanism by which epinephrine influences inflammatory response and wound healing is not well defined. Here we demonstrate that epinephrine alters the neutrophil (polymorphonuclear leukocyte (PMN))-dependent inflammatory response to a cutaneous wound....
Plant-based extracts present a large source of natural immune modulators, many of which have been used in traditional medicine for centuries. Recent research efforts have identified plant extracts as potential modulators of Toll-like receptors (TLRs), the first responders in immunological defenses in normal and disease conditions. This review aims ...
Cellular directional migration in an electric field (galvanotaxis) is one of the mechanisms guiding cell movement in embryogenesis and in skin epidermal repair. The epithelial sodium channel (ENaC), in addition to its function of regulating sodium transport in kidney, has recently been found to modulate cell locomotory speed. Here we tested whether...
Background
Healing chronic wounds is an ongoing challenge for clinicians and poses a serious public health burden. Electrical stimulation (ES), broadly defined as the application of electrical current via electrodes placed on the skin adjacent to or directly within the wound, has been proposed as a therapeutic modality over a century ago, and rece...
Toll-like receptors (TLRs) are considered to be the first responders in the defense against invading pathogens. TLR engagement by ligands triggers inflammatory responses in injury and trauma, and thus can impair or contribute to the healing process, depending on TLRs expression pattern, cellular localization, signaling, and deployment of inflammat...
