Somatosensory stimuli are encoded by molecularly and anatomically diverse classes of dorsal root ganglia (DRG) neurons. In this issue of Neuron, three papers demonstrate that the Runx transcription factors, Runx1 and Runx3, respectively regulate the molecular identities and spinal terminations of TrkA+ nociceptive neurons and TrkC+ proprioceptive neurons. These findings emphasize the importance...
Lymphoid organs are supplied by many nerve endings associated with different kinds of cells and macrophages. The role of this innervation on the release of locally active molecules is still unclear. Lingual tonsils belong to Waldeyer's Ring, in close association with palatine tonsils and nasopharyngeal (adenoids) tonsils, thus constituting part of NALT (nasal-associated lymphoid tissue) togethe...
Following sciatic nerve transection in adult rats, a proportion o f injured dorsal root ganglion (DRG) neurons die, through apoptosis, over the following 6 months. Axotomy also has effects on expression of neurotrophins (NGF, BDNF, and NT-3) and their receptors (trkA, trkB, trkC, and p75NTR) in DRG as shown by in situ hybridisation or Northern blotting. Previous groups showed that administratio...
Growth factors are known to regulate glioma proliferation. The glioma cell lines U87 and T98G were examined for evidence of an autocrine stimulatory loop involving the neurotrophin family of growth factors. Although neurotrophin-3 and TrkC RNA were detected by reverse transcription-PCR, there was no evidence of significant interaction between neurotrophin-3 and its cognate receptor TrkC. The mi...
The RUNX transcription factors are key regulators of lineage specific gene expression in developmental pathways. The mammalian RUNX genes arose early in evolution and maintained extensive structural similarities. Sequence analysis suggested that RUNX3 is the most ancient of the three mammalian genes, consistent with its role in neurogenesis of the monosynaptic reflex arc, the simplest neuronal ...
Neurotrophins have multiple functions during peripheral nervous system development such as controlling neuronal survival, target innervation and synaptogenesis. Neurotrophin specificity has been attributed to the selective expression of the Trk tyrosine kinase receptors in different neuronal subpopulations. However, despite overlapping expression of TrkB and TrkC in many sensory ganglia, brain-...
Neurotrophin-3 (NT-3), its cognate receptor trkC, and voltage-gated calcium channels are coexpressed by embryonic pyramidal neurons before target contact, but their functions at this stage of development are still unclear. We show here that, in vitro, anti-NT-3 and anti-trkC antibodies blocked the increase, and NT-3 reversed the decrease in the number of calbindin-D(28k)-positive pyramidal neur...
