CD14 blockade to prevent ischemic injury to donor organs

The purpose of this review is to highlight the potential role for the cluster of differentiation protein 14 (CD14), a co-receptor for toll-like receptor (TLR) signals and as a proximal target for innate immune signals induced during procurement of solid organs for transplantation. CD14 facilitates the detection of multiple pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) by various TLRs. All solid organs used for transplantation are exposed to PAMPs and DAMPs generated during the course of procurement that inevitably trigger injurious inflammatory responses in the donor organ.
