Phrenic Motor Neuron Expression of Receptors Known to Elicit Phrenic Motor Facilitation After Daily Acute Intermittent Hypoxia Preconditioning

The FASEB Journal, 2017
Spinal serotonin receptor activation elicits a form of respiratory motor plasticity known as phrenic motor facilitation (pMF). One specific form of pMF is phrenic long‐term facilitation (pLTF) following acute intermittent hypoxia (AIH) exposure.

Postnatal survival of phrenic motor neurons is promoted by BDNF/TrkB.FL signaling

Journal of Applied Physiology
During early postnatal development, BDNF/TrkB signaling promotes PhMN survival. Inhibition of BDNF/TrkB signaling in early postnatal development does not impact PhMN size. Inhibition of BDNF/TrkB signaling in early postnatal development does not impact the number or CSA of DIAm fibers.

Phrenic Motor Neuron Fractalkine Signaling to Nearby Microglia Regulates Phrenic Long-Term Facilitation

Physiology
Although microglia are traditionally regarded as innate CNS immune cells, recent studies demonstrate that microglia also play key roles in normal CNS functions. For example, microglia engage in bidirectional communication with other cell types ( e.g., neurons) to regulate diverse processes including neuronal excitability, architecture and synaptic ...

[Dendrite projection zones in the phrenic motor neurons of the cat].

Biulleten' eksperimental'noi biologii i meditsiny, 1986
The fields of dendrite arborization (projections) were examined in phrenic nuclei of adult cats. Six types (five radial and one longitudinal) of phrenic motoneuron dendrites have been determined. The radial dendrites can project to lamina VIII or VII, to lateral and ventrolateral locomotor nuclei and to all funiculi of the white matter surrounding the ...

Heterogeneous Distribution of Mitochondria and Succinate Dehydrogenase Activity in Phrenic Motor Neurons

Physiology
Neuromotor control of diaphragm muscle (DIAm) involves size-dependent recruitment of phrenic motor neurons (PhMNs). To accomplish breathing, only slow (type S) and fast, fatigue resistant (type FR) DIAm motor units are recruited. Thus, type s and FR DIAm motor units are very active in sustaining ventilation throughout life.

Phrenic motor nucleus astrocytic density and morphology in a rodent model of respiratory motor neuron death

Physiology
Intrapleural injection of cholera toxin B fragment conjugated to saporin (CTB-SAP) selectively kills phrenic motor neurons in the cervical spinal cord, and mimics aspects of neurodegenerative diseases including breathing deficits. In addition, phrenic plasticity is enhanced following 7 days (d) of CTB-SAP vs. control rats, whereas plasticity in 28d CTB-
