Injured neurons in the mammalian central nervous system (CNS) do not normally regenerate their axons after injury. Neurotrauma to the CNS usually results in axonal damage and subsequent loss of communication between neuronal networks, causing long-term functional deficits. For CNS regeneration, repair strategies need to be developed that promote regrowth of(More)
The primary olfactory pathway in adult mammals has retained a remarkable potential for self-repair. A specialized glial cell within the olfactory nerve, called olfactory ensheathing cell (OEC), and their associated extracellular matrix are thought to play an important role during regenerative events in this system. To gain insight into novel molecules that(More)
Members of the epidermal growth factor family of receptors have long been implicated in the pathogenesis of various tumors, and more recently, apparent roles in the developing heart and nervous system have been described. Numerous ligands that activate these receptors have been isolated. We report here on the cloning and initial characterization of a second(More)
Olfactory ensheathing glia (OEG) have been used to improve outcome after experimental spinal cord injury and are being trialed clinically. Their rapid proliferation in vitro is essential to optimize clinical application, with neuregulins (NRG) being potential mitogens. We examined the effects of NRG-1beta, NRG-2alpha, and NRG3 on proliferation of(More)
LIGHT (TNFSF14), a tumor necrosis factor superfamily member expressed by activated T cells, binds to herpes virus entry mediator (HVEM) which is constitutively expressed by T cells and costimulates T cell activation in a CD28-independent manner. Given interest in regulating the effector functions of T cells in vivo, we examined the role of LIGHT-HVEM(More)
The CD2 family is a growing family of Ig domain-containing cell surface proteins involved in lymphocyte activation. Here we describe the cloning and expression analysis of a novel member of this family, B lymphocyte activator macrophage expressed (BLAME). BLAME shares the structural features of the CD2 family containing an IgV and IgC2 domain and clusters(More)
• IL-3 receptor α (CD123) expression is elevated in CML progenitor and stem cells compared to healthy donors • CD123 monoclonal antibody targeting represents a novel, potentially clinically relevant, approach to deplete CML progenitor and stem cells Abstract Despite the remarkable efficacy of tyrosine kinase inhibitors (TKIs) in eliminating differentiated(More)
