Mature retinal ganglion cells (RGCs) cannot normally regenerate axons into the injured optic nerve but can do so after lens injury. Astrocyte-derived ciliary neurotrophic factor and leukemia inhibitory factor have been identified as essential key factors mediating this effect. However, the outcome of this regeneration is still limited by inhibitors(More)
Activation of heterotrimeric G proteins, such as G(12/13) and G(q), by cell surface receptors is coupled to the regulation of numerous cellular functions controlled by activated Rho GTPases. Previous studies have implicated the Rho guanine nucleotide exchange factor (RhoGEF) leukemia-associated RhoGEF (LARG) as a regulatory protein receiving stimulatory(More)
Expression of the human CCR2 receptors, CCR2a and CCR2b, in mammalian cells results in ligand-dependent changes in the activity of multiple cellular signal transduction pathways, mediated in most cases by pertussis toxin-sensitive heterotrimeric G proteins of the Gi/o subfamily. In addition, CCR2a and CCR2b receptors have been shown to couple to Gq family(More)
