Abstract Objective The aim was to identify the critical levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor-A in umbilical cord blood that could be used as markers for predicting the central nervous system (CNS) damage and retinopathy of prematurity (ROP) in preterm infants. Study Design A total of 158 preterm infants, born at 22 to 34 weeks of gestation, were evaluated in the first week after birth and at 36 to 37 weeks of postconceptual age. Results A significant relationship between CNS changes and concentrations of IL-6 (p < 0.001) and TNF-α (p < 0.001) in umbilical cord blood at 22 to 34 weeks of gestation was determined. The concentration of IL-6 >13.0 pg/mL predicts significant CNS damages in 36 to 37-week infants (p = 0.013). ROP was diagnosed in 24.8% infants (n = 149). It was detected that the levels of TNF-α >116.4 pg/mL (p < 0.001) and IL-6 >13.0 pg/mL (p < 0.05) in umbilical cord blood could predict 2 to 3/3 to 4 stages of ROP. Conclusion Critical values of IL-6 and TNF-α in predicting ≥grade III intraventricular hemorrhage in the early adaptation and in predicting marked CNS damages and severe ROP stages in the later adaptation of preterm infants were determined.

Background: Central pro-inflammatory cytokine (PIC) signal is involved in neurological deficits after transient global ischemia induced by cardiac arrest (CA). The present study was to examine if blocking acid sensing ion channels (ASICs) using amiloride in the Central Nervous System can alleviate neurological deficits after the induction of CA and further examine the participation of PIC signal in the hippocampus for the effects of amiloride. Methods: CA was induced by asphyxia and then cardiopulmonary resuscitation was performed in rats. Western blot analysis and ELISA were used to determine the protein expression of ASIC subunit ASIC1 in the hippocampus, and the levels of PICs. As noted, it is unlikely that this procedure is clinically used although amiloride and other pharmacological agents were given into the brain in this study. Results: CA increased ASIC1 in the hippocampus of rats in comparison with control animals. This was associated with the increase in IL-1β, IL-6 and TNF-α together with Caspase-3 and Caspase-9. The administration of amiloride into the lateral ventricle attenuated the upregulation of Caspase-3/Caspase-9 and this further alleviated neurological severity score and brain edema. Inhibition of central IL-6 and TNF-α also decreased ASIC1 in the hippocampus of CA rats. Conclusion: Transient global ischemia induced by CA amplifies ASIC1a in the hippocampus likely via PIC signal. Amiloride administered into the Central Nervous System plays a neuroprotective role in the process of global ischemia. Thus, targeting ASICs (i.e., ASIC1a) is suggested for the treatment and improvement of CA-evoked global cerebral ischemia.

Key Points The central nervous system can be a direct target of alloreactive T cells during GVHD. Central nervous system damage in mouse models of GVHD lead to deficits in learning and increased anxiety behavior.

Injuries to nerves vary in their consequences, from weakened sensation and motor function to partial or complete paralysis. In the latter case, affecting about twenty thousand Americans yearly, the injury is debilitating and results in a significant decrease in quality of life. Currently there is no effective treatment for damage to the central nervous system, in particular the spinal cord. Compared to the injuries to the central nervous system, damage in the peripheral nerves, is more common, with about sixty thousand occurrences annually. The cost of associated surgical procedures and due to loss of function is in the billions. In this thesis we present work towards the construction and testing of a fully cellular, patented nerve graft, one amongst the first of its kind. For the fabrication of the graft we are the first to employ bioprinting (either implemented through a special purpose 3D bioprinter or manually), a novel tissue engineering method rapidly gaining acceptance and utility. We first review the status of bioprinting. We then detail the fabrication process. Next we report on the testing of the graft in an in vivo animal model through electrophysiology and histology. This is followed by the introduction of a novel in vitro model, aimed at providing a fast, inexpensive and reliable method to test engineered nerve grafts. We describe our work on the optimization of the in vitro assay and then the testing of the graft using the optimized assay. We conclude with a summary of our accomplishments and make suggestions for some exciting future applications of our approach.
