Araldi D, Bogen O, Green PG, & Levine JD. Role of Nociceptor Toll-Like Receptor 4 (Tlr4) in Opioid-Induced Hyperalgesia and Hyperalgesic Priming. (2019). J Neurosci 39 (33):6414-6424.
IT-10: IB4-SAP; IT-11: SSP-SAP
Objective: To evaluate the hypothesis that hyperalgesia and priming induced by opioids are mediated by similar nociceptor mechanisms.
Summary: Treatment with isolectin B4 (IB4)-saporin or SSP-SAP (which deplete IB4+ and peptidergic nociceptors, respectively), or their combination, prevented systemic LDM-induced hyperalgesia, but not priming. HDM-induced priming, but not analgesia, was markedly attenuated in both saporin-treated groups.
Dose: IB4-SAP was diluted in saline and a dose of 3.2 μg in a volume of 20 μl administered intrathecally. SSP-SAP was diluted in saline and a dose of 100 ng in a volume of 20 μl was administered intrathecally.

Episodic stimulation of central chemoreceptor neurons elicits disordered breathing and autonomic dysfunction in volume overload heart failure. (2019). Am J Physiol Lung Cell Mol Physiol2019/10/17.
Objective: To determine the role of the central chemoreflex in the development of respiratory and autonomic dysfunction in volume overload heart failure (HF).
Summary: Episodic hypercapnic stimulation triggers ventilatory plasticity and elicits cardiorespiratory abnormalities in HF that are largely dependent on retrotrapezoid nucleus (RTN) chemoreceptor neurons.
Dose: Bilateral injections of SSP-SAP, 0.6 ng/30 nL, into the RTN were administered to destroy chemoreceptor neurons.

Objective: To examine the contribution of two lower brainstem nuclei that could be implicated in CO2 and hypoxia-induced arousal.
Summary: RTN, a brainstem nucleus that mediates the effect of brain acidification on breathing, also contributes to arousal elicited by CO2 but not hypoxia.
Dose: To ablate the retrotrapezoid nucleus (RTN), SSP-SAP was administered (2.4 ng) through bilateral injections via a dorsal craniotomy.

Summary: This review describes the neurons of the retrotrapezoid nucleus (RTN), their transcriptome, developmental lineage, and anatomical projections. The authors also review their contribution to CO2 homeostasis and to the regulation of breathing automaticity during sleep and wake.
Dose: Local injection of SSP-SAP to kill RTN neurons.
Wercberger R, & Basbaum AI. Spinal cord projection neurons: a superficial, and also deep, analysis. (2019). Curr Opin Physiol
Summary: Modern approaches to map complex neural circuits require knowledge of the molecular language that defines cell type specificity. However, with few exceptions, NK1R remains the marker consistently used to define projection neurons and even to interrogate their contribution to pain and itch:
(Mantyh et al., 1997, Science 278:275–279.) The first of two studies demonstrating that SP-SAP-mediated ablation of dorsal horn NK1R-expressing neurons reduces injury-induced hyperalgesia.
(Carstens et al. 2010, Neuroreport. 21:303–308.) In this paper SP-SAP-mediated ablation of dorsal horn NK1R-expressing neurons reduced pruritogen-evoked scratching.

Objective: To determine the central pathway for mechanical itch.
Summary: NPY-Y1 signaling regulates the transmission of innocuous tactile information by establishing biologically relevant thresholds for touch discrimination and mechanical itch reflexes. neither the evoked nor spontaneous scratching seen following activation of Y1Cre neurons was affected by ablation of the GRPR+ neurons. NK1R+ neuron ablation failed to modulate mechanically evoked itch.
Dose: P28 mice were given a single intrathecal (i.t.) injection of either Bombesin-SAP (400 ng in 5 mL 0.9% sterile saline) to ablate GRPR+ cells or SSP-SAP to ablate NK1r+ neurons (100 ng in 5 mL 0.9% sterile saline). Littermate controls received Blank-SAP (equal mass in 5 mL 0.9% sterile saline).

Objective: Hippocampal GABA neurons were targeted for selective elimination to determine whether a focal hippocampal GABAergic defect in an otherwise normal brain can initiate cryptogenic temporal lobe epilepsy with hippocampal sclerosis.
Summary: Hippocampal GABAergic dysfunction is epileptogenic and can produce the defining features of cryptogenic temporal lobe epilepsy.
Dose: Intrahippocampal injections of SSP-SAP (0.4 ng/10 nL) were performed using a 0.5-μL Neuros Syringe lowered into four hippocampal sites along both the transverse and longitudinal hippocampal axes bilaterally.

Dose: A total of 6 microinjections (120 nl/injection; 3 rostrocaudally aligned injections per side) were made 100-200 μm below the lower edge of the facial motor nucleus 2 mm lateral to the midline. Experimental rats received either 0.6 ng, 1.2 ng, or 2.4 ng of SSP-SAP per injection.
Objective: To test how important the retrotrapezoid nucleus (RTN) is to PCO2 homeostasis and breathing during sleep or wake.
Summary: Near complete RTN destruction in rats virtually eliminates the CRC but HVR persists and sighing and the state-dependence of breathing are unchanged. Under normoxia, RTN lesions cause no change in VE but alveolar ventilation is reduced by at least 21%, probably because of increased physiological dead volume. RTN lesions do not cause sleep apnea during SWS, even under hyperoxia.
Vetter I. Toxins in Neurobiology: New tools from old molecules. (2018). Neurosci Lett, 679 1-3. 2018/05/09.
Review Editorial: The selective ablation of neurokinin-1 receptor-expressing neurons by SP-SAP revealed a key role for the preBötzinger complex in the generation of respiratory rhythm. Toxin-mediated neuronal ablation may also find therapeutic applications, such as the treatment of severe refractory pain in terminally ill patients by intrathecal SP-SAP which causes selective loss of neurokinin-1 receptor-expressing neurons in the spinal cord dorsal horn.

Dose: Ablation of Neurokinin-1 receptor (NK-1R)- expressing neurons in the rat rostral ventromedial medulla (RVM), by micro-injection of the specific neurotoxin SSP-SAP.
Objective: To evaluate SSP-SAP in treatment of tactile hypersensitivity for Chronic Post-Thoractotomy Pain (CPTP).
Summary: SSP-SAP 3 weeks before thoracotomy and rib retraction (TRR) was able to completely prevent CPTP, assayed by tactile hypersensitivity.

Dose: SSP-SAP was prepared in saline (5 ng/mL), and 20 mL was injected intrathecally into rats, 14 days before nociceptive tests.
Objective: To determine the the mechanisms mediating the induction of opioid-induced hyperalgesia and the prolongation of prostaglandinE2-induced hyperalgesia in type II hyperalgesic priming.
Summary: Understanding the mechanisms responsible for the induction of type II hyperalgesic priming, a form of neuroplasticity in the peripheral terminal of the primary afferent nociceptor, may provide useful information for the design of drugs with improved therapeutic profiles to treat neuroplasticity induced by chronic use of opioids.
Ferrari LF, Khomula EV, Araldi D, & Levine JD. Cd44 Signaling Mediates High Molecular Weight Hyaluronan-Induced Antihyperalgesia. (2018). The Journal of Neuroscience, 38 (2):308-321.
Dose: Both IB4-SAP and SSP-SAP were diluted in saline to doses previously shown to deplete nonpeptidergic (3.2 mcg/rat for IB4-SAP) and peptidergic (100 ng/rat for SSP-SAP) fibers. The toxins were administered intrathecally, in a volume of 20 mcl, 14 d before intradermal injection of LMWH on the dorsum of the hindpaw. Treatment with either conjugate, or a combination of the two, did not significantly affect mechanical nociceptive threshold.
Objective: To study the role of the cognate hyaluronan receptor, CD44, signaling in anti-hyperalgesia induced by high molecular weight hyaluronan (HMWH).
Summary: These results demonstrate the central role of CD44 signaling in HMWH-induced anti-hyperalgesia, and establish it as a therapeutic target against inflammatory and neuropathic pain.

Dose: Two protocols were applied for SSP-SAP injections. In immunostaining experiments, to determine how many Phox2b-containing cells were destroyed, a total volume of 100 nl of PBS containing 6 ng of SSP-SAP (3 ng in 50 nl; 2 injections) was injected into one side of the NTS and the contralateral NTS was used as a control (no injection). For in vivo experiments, to determine whether loss of Phox2b cells led to impaired HCVR, bilateral injections with a total volume of 200 nl of PBS containing 6 ng (1.5 ng in 50 nl per injection; 2 injections per side) or 12 ng (3 ng in 50 nl per injection; two injections per side) of toxin into NTS. Breathing was studied in conscious, freely moving mice treated with SSP-SAP and Blank-SAP.
Objective: To investigate whether paired-like homeobox 2b (Phox2b)-expressing NTS neurons are recruited in hypercapnic ventilatory response (HCVR) and whether these neurons exhibit intrinsic chemosensitivity.
Summary: Respiratory deficits caused by injection of SSP-SAP into the NTS are attributable to proportional lesions of CO2/H+-sensitive Phox2b-expressing neurons.
