Objective: To study the roles of the locus coeruleus (LC) to medial prefrontal cortex (mPFC) pathway in pain empathy in rats.
Summary: Results indicate that noradrenergic innervations in the mPFC mediate empathy for pain in rats via the α1 and β receptors.
Dose: Noradrenergic innervations of the mPFC were selectively eliminated through intra-mPFC injections of Anti-DBH-SAP.

Summary: Astrocytes are critical regulators of neuronal function in the central nervous system (CNS). Astrocytes in the spinal dorsal horn (SDH) increase intracellular Ca2+ levels following intraplantar injection of the noxious irritant, formalin, however the underlying mechanisms remain unknown. The authors investigated these mechanisms by focusing on the role of descending noradrenergic (NAergic). Activation of α1A-adrenaline receptors via descending LC-NAergic signals may be a common mechanism underlying astrocytic Ca2+ responses in the SDH evoked by noxious stimuli, including chemical irritants
Dose: Intrathecal treatment with Anti-DBH-SAP, which kills SDH-projecting NAergic neurons, attenuates formalin pain (5.0 µg/20 µl; Martin et al., 1999)

Summary: This review discusses the pharmacological manipulation interrogation strategies that have been used to examine the functionality of diffuse noxious inhibitory controls (DNIC) and descending control of nociception (DCN).
Dose: Anti-DBH-SAP is one of the drugs tested to influence DNIC expression (Table 1). They reference a publication that reported that icv injection of Anti-DBH-SAP abolished DCN expression (Table 2). Anti-DBH-SAP (5 μg/5 μl) was injected in the left ventricle. Lesion of the LC resulted in failure of DNIC, an effect that mimics what is observed behaviorally after chronic TBI. See Irvine et al., 2020.

Summary: There is strong comorbidity between chronic pain and depression. This study explores how this comorbidity occurs. The authors refer to published research that shows icv administration of anti-DBH-SAP or intra-LC administration of lidocaine dampened the evoked pain in conditions of long-term nerve-injury. However, icv injection of anti-DBH-SAP disrupts all noradrenergic nuclei (A1-A7), some of which contribute to sensorial hypersensitivity.

Front Physiol 12:649535. doi: 10.3389/fphys.2021.649535
Summary: The study sought to determine the role of noradrenergic neurons in hypertonic saline infusion (HSI)-induced hemodynamic recovery. Findings show that together the A1 and A2 neurons are essential to HSI-induced cardiovascular recovery in hypovolemia.
Dose: Medullary catecholaminergic neurons were lesioned by nanoinjection of Anti-DBH-SAP (0.105 ng·nl−1) into A1, A2, or both (LES A1; LES A2; or LES A1+A2, respectively). Sham rats received nanoinjections of unconjugated saporin in the same regions.

Summary: In this study, the authors investigated the participation of A5 noradrenergic neurons in neonates (P7-8 and P14-15) in the control of ventilation during hypoxia and hypercapnia. data suggest that noradrenergic neurons of the A5 region in neonate rats do not participate in the control of ventilation under baseline and hypercapnic conditions, but exert an inhibitory modulation on breathing variability under hypoxic challenge in early life (P7-8).
Dose: Anti-DBH-SAP (420 ng/μL) or saporin (SAP, control) was injected into the A5 region of neonatal male Wistar rats.

Objective: To assess the phenotype of amylin activated LPBN (lateral parabrachial nucleus) neurons, especially to confirm the CGRPergic phenotype and to uncover the specific role of NA (noradrenaline) signaling from the AP to the LPBN.
Summary: The present study confirmed the central role of the LPBN in propagating amylin’s and sCT’s hypophagic action, and particularly the importance of AP → LPBN NA signaling in the mediation of this process, through the activation of LPBN (CGRP and non-CGRP) neurons.
Dose: A specific lesion of about half of the total AP NA population with the immunotoxin anti-DBH-SAP) was sufficient to abolish the hypophagic effect of amylin in rats and also reduced amylin’s ability to induce c-Fos expression in AP neurons. The neuronal pathways used to process the physiological response to amylin were investigated using 50-ng injections of Anti-DBH-SAP (Cat. #IT-03) into the area postrema (AP) or 25 ng into the lateral parabrachial nucleus (Potes et al., 2010).

Summary: Review. Immunolesion of paraventricular nucleus (PVN)-projecting norepinephrine (NE) neurons with Anti-DBH-SAP attenuates acute stress reactivity (interestingly, to restraint), but it does not inhibit somatic or HPA axis responses to stress in any simple way (Flak et al., 2014). PVN-projecting norepinephrine (NE) neurons appear to be responsible for acute responses to systemic stressors, but they do not appear to be important in mediating effects of chronic stress (Ritter et al., 2003).
Dose: Flak et al. injected 8.82 ng of Anti-DBH-SAP into the PVN. Ritter et al. injected 42 ng into the PVN.

Summary: The authors hypothesize that dysfunctional descending noradrenergic and serotonergic pain control circuits may contribute to the loss of diffuse noxious inhibitory control (DNIC), a critical endogenous pain control mechanism, weeks to months after traumatic brain injury (TBI). Results suggest that TBI causes maladaptation of descending nociceptive signaling mechanisms and changes in the function of both adrenergic and serotonergic circuits. Such changes could predispose those with TBI to chronic pain. Dose: Anti-DBH-SAP (5 μg/5 μl) was injected in the left ventricle. Lesion of the LC resulted in failure of DNIC, an effect that mimics what is observed behaviorally after chronic TBI.

Objective: To determine if the ablation of Cl neurons mitigate the high blood pressure induced by high-salt intake.
Summary: Data show that hypertension induced by high-salt intake is dependent on Cl neurons.
Dose: Bilateral injections of 2.4 ng/100 nl of Anti-DBH-SAP. The total number of TH+ neurons in the AS region was reduced by 37 ± 13% in the anti-DBH-SAP group when compared to control. The injection of anti-Df3H-SAP into the RVLM reduced 80% of the TH+ neurons in the total number of Cl neurons, and 38% in the AS region.

Summary: Highly glucose-sensitive cells in the ventrolateral medulla send catecholaminergic projections to the PVH. These projections can be selectively destroyed by Anti-DBH-SAP “DSAP” lesions, wherein a toxin (saporin) is directed at nondopaminergic cells that express the enzyme necessary for synthesis of epinephrine and norepinephrine (the enzyme is dopamine beta hydroxylase). DSAP experiments show that catecholaminergic projections from glucose-sensitive cells in the ventrolateral medulla are necessary for all responses to glucoprivation, including increases in epinephrine secretion, glucocorticoid secretion, sex behavior, and food intake (reviewed by Ritter et al., 2019).

Objective: To investigate the contribution of RVLM-C1 neurons on breathing disorders in chronic heart failure (CHF).
Summary: RVLM-C1 neurons play a critical role in the maintenance of altered breathing patterns in CHF rats and highlighted their contribution to the worsening of cardiac function during central chemoreflex activation. DBH-SAP treatment decreased active expiration in CHF rats and deleterious effects of central chemoreflex activation on diastolic cardiac function and cardiac autonomic control were blunted.
Dose: Stereotaxic bilateral injections of Anti-DBH-SAP (5 ng/150 nl).

Objective: To determine the effects of NE depletion on the eCB system.
Summary: The results suggest that the endocannabinoids (eCB) system may be more responsive in males than females under conditions of NE perturbation, thus having potential implications for sex-specific treatment strategies of stress-related psychiatric disorders.
Dose: The authors used a DBH knockout model and DSP-4 (a compound that depletes endogenous norepinephrine and enhances release of [3H]norepinephrine). More specific mechanisms for further corroboration could be undertaken, such as using Anti-DBH-SAP to provide a more complete lesion compared to DSP-4.

IT-01: 192-IgG-SAP and IT-03: Anti-DBH-SAP
Summary: A review of the tools for creating animal models of Alzheimer’s Disease. 192-IgG-SAP binds selectively and irreversibly to low-affinity nerve growth factor receptor interrupting cholinergic neuronal protein synthesis was employed. Anti-DBH-SAP binds dopamine-β-hydroxylase, which is not only localized mainly in the cytosol, but also at the plasma membrane surface of noradrenergic neurons. Anti-DBH-SAP produced specific and dose-dependent depletions of locus coeruleus neurons, with no effects on other cholinergic, dopaminergic or serotonergic neuronal populations. The possibility to induce a partial or total noradrenergic loss (by varying the injected dose) makes this immunotoxic approach an ideal model to study events within the noradrenergic projection system, as they occur during age-related demise of locus coeruleus in humans.

Objective: The mechanisms underlying reduced neurogenesis in Parkinson’s Disease (PD) are not well established. The authors tested the hypothesis that noradrenergic and dopaminergic depletion, as occurs in PD, impairs hippocampal neurogenesis.
Summary: Mechanisms of neurotransmitter-based regulation of cognition and hippocampal neurogenesis may well overlap under certain conditions but the present results do not suggest a simple relationship associated with the degeneration of the two most prominently affected transmitter systems in PD.
Dose: Rats received 1 mcg Anti-DBH-SAP icv.

Objective: To examine noradrenergic dysfunction in AD-related cognitive decline in humans and its potential involvement in AD pathology and disease progression.
Summary: The authors discuss noradrenergic dysfunction in AD-related cognitive decline. The research focuses on animal models to allow the validation of the noradrenergic hypothesis of AD, including those based upon the Anti-DBH-SAP-mediated ablation of LC. The article also addresses how astrocytes may participate in the regulation of neurogenesis, a new strategy for preventing LC neuron loss.
Dose: DBH (–/–) knockout mice do not seem to offer the possibility to obtain partial or graded neurotransmitter depletions. In light of these limitations, the authors used Anti-DBH-SAP which is able to target noradrenergic neurons in the LC with unprecedented selectivity and efficiency. Anti-DBH-SAP was injected bilaterally into the LC.

Objective: To investigate the role of hindbrain catecholamine neuron pathways and their contribution to long-term energy homeostasis by controlling obesogenic sensitivity to a high-fat, high sucrose choice diet.
Summary: The authors show that catecholamine neurons (primarily in the VLM and NTS) convey essential feedback signals to enable long-term adaptive control of energy metabolism when animals consume a predominantly carbohydrate diet. This is the first report specifically associating this projection system with the long-term control of adiposity.
Dose: (Cat. #KIT-03; Anti-DBH-SAP and IT-18; Mouse IgG-SAP). Catecholaminergic projections to the PVH and related parts of the forebrain were lesioned with bilateral injections each consisting of 42 ng/200 nL of Anti-DBH-SAP or equimolar amounts of control Mouse IgG-SAP.

Objective: To determine the role of the brainstem CA system in ventilatory control under normocapnic and hypercapnic conditions during different phases of development (P7-8, P14-15 and P20-21) in male and female Wistar rats.
Summary: Brainstem CA neurones produce a tonic inhibitory drive that affects breathing frequency in P7-8 rats and provide an inhibitory drive during hypercapnic conditions in both males and females at P7-8 and P14-15.
Dose: Anti-DBH-SAP (420 ng/μL – 1 μL for P0-1; 1.5 μL for P7-8; 2.0 μL for P13-14) was injected into the 4th ventricle of neonatal Wistar rats of both sexes. Control rats were injected with vehicle (PBS, 0.01 M, pH 7.4) or unconjugated saporin (Cat. #PR-01), with respective volumes for each age, as described for the Anti-DBH-SAP group. All injections were performed using a microinjector pump over a period of 5 min to allow drug diffusion.

Summary: Dopamine loss is central to Parkinson’s disease and is often accompanied by noradrenergic denervation of the locus coeruleus. In this work the authors examined the role this loss plays in L-DOPA therapy using a rat Parkinson’s disease model.
Dose: Rats received 10 μg of anti-DBH-SAP into the left lateral ventricle. Loss of norepinephrine (NE) neurons did not affect behavior, but lesioned animals were less responsive to the pro-motor therapeutic effects of L-DOPA.

Summary: The authors used Anti-DBH-SAP to re-examine the contribution of noradrenergic pathways to nociception and to morphine analgesia. They also evaluated morphine analgesia in the formalin test and found that toxin-treated animals exhibited enhanced morphine analgesia. These results establish the utility of using this immunotoxin to selectively destroy subpopulations of noradrenergic cell groups and provide evidence that acute and persistent nociception are differentially regulated by descending noradrenergic pathways.
Dose: Intrathecal treatment with Anti-DBH-SAP attenuates formalin pain (5.0 µg/20 µl).
