Objective:  To investigate whether enhanced activation of the patch compartment contributes to habitual behavior.
Summary:  The dorsolateral patch compartment may mediate habit formation by altering information flow through basal ganglia circuits.
Dose:  A volume of 2 ul of Dermorphin-SAP (17 ng/ul or an equivalent amount of unconjugated SAP (as a control) was infused bilaterally, at a rate of 0.5 ul/min.

Mice were injected i.v. with either 100 µg of 1:1 molar mixture of biotinylated CD63 antibody and Streptavidin-ZAP (60 µg mAb + 40 µg SAP) or with 40 µg SAP alone. All injections were performed in 200 µl PBS.

IT-06: Mac-1-SAP / PR-01: Saporin
Objective: To determine whether inflammatory macrophages contribute to neuropathic pain associated with type 2 diabetes-mellitus (T2DM).
Summary: Inhibitory agents for macrophage-driven neuroinflammation could be potential candidates for novel pharmacotherapy against intractable neuropathic pain.
Dose: Injections of Mac-1-SAP or unconjugated Saporin (10 μl) were administered 3 times every 2 days. Perineural administration of Mac-1-SAP improved high-fat diet (HFD)-induced mechanical allodynia and the accumulation of F4/80+ macrophages and the upregulation of inflammatory mediators in the SCN after HFD-feeding.

Sci Adv 4:1-12. doi: 10.1126/sciadv.aas9846

Objective: To identify therapeutic targets for alleviating mechnical allodynia, a sign/symptom of arthritis.
Summary: The pannexin-1 (Panx1) channel is validated as a target; blockade of P2X7 receptors or ablation of spinal microglia prevented and reversed mechanical allodynia.
Dose: Mac-1-SAP and unconjugated Saporin (15 mg per intrathecal injection on days 0, 1, and 2).  The specific depletion of spinal lumbar microglia attenuated the development of MIA-induced hypersensitivity indicating that spinal microglia causally contribute to the development of mechanical allodynia.  By contrast, intrathecal injection of Control (unconjugated Saporin) did not alter the development of MIA-induced mechanical allodynia.

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 investigate if serotonin-expressing neurons in the Raphe pallidus/parapyramidal region (RPa/PPy) are also involved in the modulation of breathing during central chemoreception activation in a PD animal model.

Objective:  Examine effects of loss of melanopsin in drakes.
Summary:  Loss of melanopsin in PMM elicits decrease in GnRH mRNA expression, gonadal regression, and sex behaviors in drakes.
Dose:  To specifically lesion melanopsin-receptive neurons, 3 μl of an anti-melanopsin-saporin conjugate (MSAP, 100 ng/ul) was injected into the lateral ventricle (n = 10). Control drakes were injected with 3 μl of equimolar unconjugated anti-melanopsin and saporin (SAP, n = 10).

KIT-31:  CCK-SAP, Saporin
Objective:  To determine the  endogenous relevance of GIderived vagal HPC communication.
Summary:  Endogenous derived vagal sensory signaling promotes HPC-dependent memory function via a multi-order brainstem–septal pathway, thereby identifying a previously unknown role for the gut–brain axis in memory control.
Dose:   A 1-µl volume of CCK-SAP (250 ng/µl) or control Saporin (250 ng/µl) was injected at two sites: 0.5 µl rostral and 0.5 µl caudal to the laryngeal nerve branch.

Objective:  To identify and characterize an antibody raised using human embryonic stem cells with potential as a cancer therapeutic.
Summary:  Antibody A19 not only binds to undifferentiated hESCs by flow cytometry, it also reacts with ovarian and breast cancer cell lines with low or no binding to normal cells.
DoseIn Vitro – Number of viable cells treated showed a decrease in cell number (Hum-ZAP mixed with A19; Streptavidin-ZAP mixed with biotinylated A19).  To determine if there were off-target effects, Hum-ZAP and chA19 were incubated with a non-binding cell line OVCAR10; no apparent cytotoxicity was observed.
In Vivo – 5 x 106 SKOV3 cells were implanted s.c. in NUDE mice and Biotinylated A19-Streptavidin-ZAP (ADC), administered ip.  The controls were free Saporin and naked A19.  By the end of 10 weeks, mice administered with the ADC saw a 60% reduction in tumor size compared to control groups.

Nat Med 23:355-360. doi: 10.1038/nm.4281

Summary: The authors investigated the mechanisms underlying opiate withdrawal in rat.  Depletion of spinal lumbar microglia by intrathecal injections of Mac-1–SAP (Cat. #IT-33; 20 mcg) decreased withdrawal behaviors and attenuated the severity of withdrawal without affecting morphine antinociception.  Unconjugated Saporin (Cat. #PR-01; 20 mcg) was used as control and had no effect on spinal CD11b immunoreactivity or naloxone-induced morphine withdrawal.

Summary: Selective depletion of spinal microglia in male rats with the targeted immunotoxin Mac-1-SAP and blockade of brain derived neurotrophic factor–TrkB signalling with intrathecal TrkB Fc chimera, but not cytokine inhibition, almost completely reversed pain hypersensitivity.  To selectively deplete microglia in the spinal cord, Mac-1-SAP was injected intrathecally.  In each group, rats received either an intrathecal injection of 12 mg/7 mL of Mac-1-SAP (n = 6-8) or equal volume of 0.9% saline (n 5 6) or the inactive unconjugated toxin, Saporin (n = 6).)
