Necrotizing enterocolitis (NEC) is the most frequent and lethal disease of the
gastrointestinal tract of preterm infants. At present, NEC is thought to develop
in the premature host in the setting of bacterial colonization, often after
administration of non-breast milk feeds, and disease onset is thought to be due
in part to a baseline increased reactivity of the premature intestinal mucosa to
microbial ligands as compared with the full-term intestinal mucosa. The increased
reactivity leads to mucosal destruction and impaired mesenteric perfusion and
partly reflects an increased expression of the bacterial receptor Toll-like
receptor 4 (TLR4) in the premature gut, as well as other factors that predispose
the intestine to a hyper-reactive state in response to colonizing microorganisms.
The increased expression of TLR4 in the premature gut reflects a surprising role
for this molecule in the regulation of normal intestinal development through its
effects on the Notch signalling pathway. This Review will examine the current
approach to the diagnosis and treatment of NEC, provide an overview of our
current knowledge regarding its molecular underpinnings and highlight advances
made within the past decade towards the development of specific preventive and
treatment strategies for this devastating disease.
