肺表面活性剂蛋白(SP)在肺功能和防御中起关键作用;SP-B和SP-C对于减少肺泡表面张力至关重要,而SP-A和SP-D是肺部宿主防御和炎症调节的关键。我们的研beplay苹果手机能用吗究兴趣围绕着了解表面活性剂蛋白在两种影响过早新生儿的严重病理中的作用。呼吸窘迫综合征(RDS)和坏死性小肠结肠炎(NEC)。

尽管由于早产过早而缺乏SP-B会导致肺功能障碍和RDS,但糖皮质激素的产前给药会通过增加SP-B mRNA稳定性来增加SP-B表达。我们已经确定了在人类SP-B mRNA 3'-非翻译区域中提高mRNA稳定性所必需的序列,现在正在鉴定与这些序列结合的蛋白质。我们的目标是定义这种调节机制,以便在不使用糖皮质激素的情况下设计疗法以加速早产婴儿的SP-B表达。

NEC是一种毁灭性的疾病往往伴随pre-maturity that results in partial or total destruction of the immature intestine via inappropriate bacterial colonization and rampant inflammation. In the lung, SP-A functions to reduce bacterial colonization and inflammation, and SP-A is expressed in the gastrointestinal tract. We found that SP-A reduces inflammatory cytokines in the intestine and colon of neonatal mice. In addition, we find that SP-A can reduce pathology in rodent models of NEC. SP-A appears to reduce levels of a key player in NEC, toll-like receptor-4 (TLR4) through increased proteasomal degradation. Our goal is to define the protective mechanism of SP-A in immature intestine and establish a link between the incidence of NEC and intestinal SP-A levels. These studies provide may a new paradigm in which the under-appreciated extra-pulmonary functions of SP-A may help protect the immature intestine. Defining the mechanism of this protection will allow us to design therapies that exploit the immunomodulatory properties of SP-A to prevent and treat NEC in prematurely-born infants.
