Beneficial microbes and probiotic species, such as Lactobacillus reuteri, produce biologically active compounds that can modulate host mucosal immunity. Previously, immunomodulatory factors secreted by L. reuteri ATCC PTA 6475 were unknown. A combined metabolomics and bacterial genetics strategy was utilized to identify small compound(s) produced by L.(More)
Dysregulated expression of miR-219, a brain-specific microRNA, has been observed in neurodevelopmental disorders, such as schizophrenia (SCZ). However, its role in normal mammalian neural stem cells (NSCs) and in SCZ pathogenesis remains unknown. We show here that the nuclear receptor TLX, an essential regulator of NSC proliferation and self-renewal,(More)
Invasive aspergillosis and other fungal infections occur in immunocompromised individuals, including patients who received blood-building stem cell transplants, patients with chronic granulomatous disease (CGD), and others. Production of reactive oxygen species (ROS) by immune cells, which incidentally is defective in CGD patients, is considered to be a(More)
