Areas of Interest:

  • Necrotizing enterocolitis (NEC) affects thousands of premature newborns in the USA every year, with an incidence ranging from 7-11% and mortality rates (15-30%) are essentially unchanged in the past 30 years. The pathogenesis of NEC remains unclear, although prematurity, formula feeding, bacterial colonization of the bowel, and mucosal injury secondary to intestinal hypoxia and ischemia have been implicated. The gap in knowledge regarding the precise pathophysiology of NEC has prevented the development of effective therapies and preventative strategies. The individual differences in patient susceptibility to NEC and its variable severity may be due to abnormalities in the balance of pro-inflammatory and anti-inflammatory mechanisms that contribute to immune homeostasis. In mammals, MAPKs are primarily deactivated by a family of dual specificity protein phosphatases (DUSP) via dephosphorylation of specific tyrosine and threonine residues. These phosphatases (MKP-1) are key regulators of the innate immune response during bacterial infection and play a significant role in the prevention and resolution of sepsis. The role of MKP-1 as an important inflammatory “watchdog” has never been investigated in the context of NEC. The overall goal of this research is to determine the mechanism by which the innate immune response leading to NEC is regulated by MKP-1.
