The safety and efficacy of cell-based therapies for neurodegenerative diseases depends on the mode of cell administration. We hypothesized that intranasally administered cells could bypass the blood-brain barrier by migrating from the nasal mucosa through the cribriform plate along the olfactory neural pathway into the brain and cerebrospinal fluid (CSF).(More)
The authors examined the processing of threat-related information in childhood anxiety with the emotional Stroop task and the dot probe task. In study 1, a nonclinical sample of 112 pupils (mean age = 9 years) performed pictorial versions of both tasks. For each task, an index indicating a bias for threat processing was computed. Positive correlations were(More)
The phospholipases D (PLD1 and 2) are signaling enzymes that catalyze the hydrolysis of phosphatidylcholine to phosphatidic acid, a lipid second messenger involved in cell proliferation, and choline, a precursor of acetylcholine (ACh). In the present study, we investigated development and cognitive function in mice that were deficient for PLD1, or PLD2, or(More)
The proliferation of astrocytes during early brain development is driven by growth factors and is accompanied by the activation of phospholipase D (PLD). Ethanol disrupts PLD signaling in astrocytes, a process which may contribute to delayed brain growth of fetuses exposed to alcohol during pregnancy. We here report that insulin-like growth factor 1 (IGF-1)(More)
CD40L has a well-established role in enhancing the immunostimulatory capacity of normal and malignant B cells, but a formulation suitable for clinical use has not been widely available. Like other TNF family members, in vivo and in vitro activity of CD40L requires a homotrimeric configuration, and growing evidence suggests that bioactivity depends on(More)
Whole tumor cell-based vaccines administered within the first 2 to 3 months after allogeneic stem cell transplantation stand out as a promising approach to enhance graft-vs.-leukemia responses. Herein, the implications of this finding for the development of strategies to improve the outcome of patients subjected to allogeneic stem cell transplantation are(More)
