Objective:  To understand the mechanism responsible for this difference in magnitude of phrenic long-term facilitation (pLTF).
Summary:  pLTF in 7d CTB-SAP treated rats is elicited primarily through TrkB and PI3K/Akt-dependent mechanisms, whereas BDNF and MEK/ERK-dependent mechanisms induce pLTF in 28d CTB-SAP treated rats.
Dose:  Rats received bilateral intrapleural injections of CTB-SAP; 25 μg dissolved in PBS.

Objective:   To test the hypothesis that A2A receptor antagonism promotes phrenic motor neuron survival and preserves diaphragm function when faced with toxic, neurodegenerative insults that lead to phrenic motor neuron death.
Summary:  The authors utilized a novel neurotoxic model of respiratory motor neuron death using intrapleural injections of CTB-SAP.   A2A receptors contribute to neurotoxic phrenic motor neuron death, an effect mitigated by A2A receptor antagonism.
Dose:   Intrapleural administration of CTB-SAP (25 μg per side) causes: 1) profound phrenic motor neuron death (~5% survival); 2) ~7-fold increase in phrenic motor neuron A2A receptor expression prior to cell death; and 3) diaphragm muscle paralysis (inactive in most rats; ~7% residual diaphragm EMG amplitude during room air breathing).

Objective: To investigate the role of serotonin (5-HT) and adenosine 2A (A2A) receptors in respiratory plasticity.
Summary: A2A receptors are necessary for respiratory plasticity early (7d), but 5-HT receptors are required late (28d).
Dose: Bilateral, intrapleural injections of: 1) CTB-SAP (25 μg), or 2) un-conjugated CTB and SAP (control) in rats.

Objective:  To explore whether exercise shows the same neuroprotective effect on induced dendritic atrophy as that seen with androgen treatment.
Summary:  Exercise following neural injury exerts a protective effect on motoneuron dendrites comparable to that seen with exogenous androgen treatment.
Dose:  Motoneurons innervating the left vastus medialis muscle were selectively killed by intramuscular injection of CTB-SAP (2 μL, 0.1%).  Saporin injection reduced the weight of the vastus medialis muscle; exercise had no effect on muscle weight.

Objective: To use a neurotoxic model of spinal motoneuron depletion, induced by injection of CTB-SAP, to investigate the possible occurrence of compensatory changes in both the muscle and spinal cord.
Summary:  Plastic changes in surviving motoneurons produce a functional restoration probably similar to the compensatory changes occurring in disease.  These changes could be  driven by glutamatergic signaling; astrocytes contacting surviving motoneurons may support this process.
Dose:  Mice received 2 injections of CTB-SAP (3 mcg CTB-Sap in 2 mcL PBS) into the medial and lateral left gastrocnemius muscle.

Objective: The authors explored the role of A2A receptors in phrenic motor neuron cell death in vivo.
Summary: A2A receptors, which contribute to motor neuron death during toxic insults, are upregulated in spared phrenic motor neurons of CTB-SAP treated rats. This is an important finding since A2A receptor upregulation may accelerate motor neuron death in neurodegenerative diseases like ALS.
Dose: CTB-SAP selectively killed nearly all phrenic motor neurons within a week and caused diaphragm paralysis (p<0.01).

Objective: Despite its fundamental importance, dysphagia (difficulty swallowing) and strategies to preserve swallowing function have seldom been studied in ALS models.
Summary: The authors report a novel experimental model using intralingual injections of cholera toxin B conjugated to saporin (CTB-SAP) to study the impact of only hypoglossal motor neuron death without the many complications that are present in ALS models.
Dose: Hypoglossal motor neuron survival, swallowing function, and hypoglossal motor output were assessed in Sprague Dawley rats after intralingual injection of either CTB-SAP (25 ug) or unconjugated CTB and SAP (controls) into the genioglossus muscle.

Objective:  To study the impact of respiratory motor neuron death.
Summary:  Intrapleural CTB-SAP mimics aspects of ALS.  Seven days of CTB-SAP enhances respiratory plasticity.
Dose:  Bilateral intrapleural injections of: 1) CTB-SAP (25 μg), or 2) un-conjugated CTB and SAP (control).

Objective:  To test the hypothesis  that distal cerebrospinal fluid-contacting nucleus (dCSF-CNs) might affect the renin-angiotensin system (RAS) in kidney injury progression.
Summary:  Less CTB-labeled neurons were found in dCSF-CNs of CTB-SAP-treated rats. Meanwhile, CTB-SAP downregulated AGT, Ang II, AT1R, NOX2, catalase, MCP-1, IL-6, fibronectin, and collagen I, and upregulated ACE2 and Mas receptor. Targeted dCSF-CNs ablation could alleviate renal inflammation and fibrosis in chronic kidney injury.
Dose: CTB-SAP (500 ng) into the lateral ventricles  over a 3-min period.

Song SY, Zhang LC. The Establishment of a CSF-Contacting Nucleus “Knockout” Model Animal. (2018) Front Neuroanat 12:22. doi: 10.3389/fnana.2018.00022

Objective:  To establish a cerebrospinal fluid (CSF)-contacting nucleus-deficient model animal using cholera toxin B subunit-saporin (CTB-SAP).
Summary:  The complete ablation occurred by Day 7 after CTB-SAP microinjection. A model animal that had no CSF-contacting nucleus was established after survival beyond that time point.  No obvious effects were observed in the vital status of the model animals, and their survival was ensured.  The common physiological parameters of model animals were stable.  The present study provides a method to establish a CSF-contacting nucleus “knockout”  model animal, which is similar to a gene knockout model animal for studying this particular nucleus in vivo.
Dose:  3 μl (500 ng) CTB-SAP was microinjected into the lateral ventricle.

Objective: To determine whether targeted ablation of cardiac sympathetic neurons (TACSN) could suppress myocardial infarction-induced adverse cardiac remodeling and left ventricle dysfunction.
Summary:  TACSN significantly alleviated sympathetic remodeling and neuroendocrine activation, attenuated cardiac hypertrophy and fibrosis, and improved the left ventricular function.  Thus, TACSN may have a beneficial effect on adverse post-infarction remodeling and left ventricle dysfunction.
Dose: 20 μl of CTB-SAP (1.2 mg/ml) was mixed with 4 μl of 3% Evans blue dye to make it visible (CTB-SAP is colorless), ensuring localization within the ganglia. The CTB-SAP/Evans blue dye solution was slowly and intermittently injected into the left stellate ganglia using a glass micropipette.

Objective: To evaluate the cardiac electrophysiologic effects of targeted ablation of cardiac sympathetic neurons (TACSN) in a canine model of chronic myocardial infarction (MI).
Summary: Targeted ablation of cardiac sympathetic neuron attenuates sympathetic remodelling and improves ventricular electrical remodelling in the chronic phase of MI. These data suggest that TACSN may be a novel approach to treating ventricular arrhythmias.
Dose: 20 μl of CTB-SAP (1.2 mg/ml) was mixed with 4 μl of 3% Evans blue dye to make it visible (CTB-SAP is colorless), ensuring localization within the ganglia. The CTB-SAP/ Evan blue dye solution was slowly and intermittently injected into the left stellate ganglia using a glass micropipette.
