Cover Story: Insulin in the brain can improve memory both in the preclinical and clinical setting. Insulin must be transported across the blood–brain barrier (BBB) to enter the brain. Peripherally administered rapamycin, an inhibitor of the mammalian target of rapamycin (mTOR), can improve memory in a mouse model of Alzheimer’s disease. It is also touted for its extension of life span and health span across multiple species. Rapamycin is a caloric restriction mimetic, eliciting a starvation response. Starvation increases insulin transport in the brain. In this article, we tested whether rapamycin could affect insulin BBB transport, which could be a mechanism for improving memory. Rapamycin treatment in mice does not affect insulin transport across the BBB but impacts brain endothelial cell binding to insulin and downstream insulin receptor signaling. View this paper.

Burn Injury: Mechanisms of Keratinocyte Cell Death

  • Hans-Oliver Rennekampff and
  • Ziyad Alharbi

Cutaneous burn injury is associated with epidermal loss in the zone of coagulation zone and delayed tissue loss in the zone of stasis. Thus, thermal stress can trigger both necrosis and regulated cell death (RCD) or apoptosis. Experimental in vitro a...
