The present study provides the first evidence that signaling occurs between B-ephrins and EphB receptors in the adult CNS in response to injury. Specifically, our combined histological and biochemical data indicate that two members of the B-class of ephrins and Eph receptors, ephrin-B2 and EphB2, are expressed by astrocytes and meningeal fibroblasts,(More)
The mechanisms by which Legionella pneumophila, a facultative intracellular parasite and the agent of Legionnaires' disease, acquires iron are largely unexplained. Several earlier studies indicated that L. pneumophila does not elaborate siderophores. However, we now present evidence that supernatants from L. pneumophila cultures can contain a(More)
The molecular mechanisms that regulate basal ganglia development are largely unknown. Eph receptor tyrosine kinases are potential participants in this process as they regulate development of other CNS regions and are expressed in basal ganglia nuclei, such as the substantia nigra (SN) and striatum. To address the role of Eph receptors in the development of(More)
