Summary: The effectiveness of the studies of the pathogenesis of AD and search for the strategies of its prevention and treatment depend on appropriate modeling of the pathological conditions in the brain leading to AD. Traditionally, the main focus on designing animal models of AD was related to the identification of brain areas and mediator systems related to memory. One model employed injections of a monoclonal antibody against growth factor receptor conjugated with saporin (192 IgG-saporin), which also resulted in the loss of cholinergic neurons and cognitive disorder

CNS Neurol Disord Drug Targets 17:106-112. doi: 10.2174/1871527317666180314115623

Objective: To establish the relationship between the depletion of orexin neurons and the number of proliferating cells in the subventricular zone.

Summary: The adult subventricular zone is affected by orexinergic signaling, the functional implication of which must be further elucidated.

Usage: 90 ng of Orexin-SAP or pyrogen-free saline was stereotaxically injected into the lateral hypothalamus (3.2 caudal, 1.7 lateral to bregma, 8.1 ventral to the skull surface) of male Wistar rats.

Objective: To investigate whether the proinflammatory cytokine MIF participates in the regulation of neuropathic hypersensitivity by interacting with and suppressing the descending dopaminergic system.

Summary: MIF functions as a braking factor in curbing dopaminergic descending inhibition in peripheral nerve injury-induced hypersensitivity by mediating Th gene methylation through G9a/SUV39H1-associated H3K9 methylation.

Usage: Anti-DAT-SAP was injected i.t. or i.c.v. with ISO-1 alone or ISO-1 combined with one of the other regulators on Day 7 post-nerve injury for 14 days, and pain behaviors, including 50% withdrawal threshold, mechanical pressure and thermal withdrawal latency, were observed throughout the 70 days post nerve injury.

Monoclon Antib Immunodiagn Immunother 37:1-11. doi: 10.1089/mab.2017.0043

Objective: To determine if an immunotoxin cocktail targeted to multiple epitopes has synergistic effects on low expression level cells, which would expand the applicable range of immunotoxin therapy for cancer.

Summary: The combination of immunotoxins with different mechanisms of action in an antibody cocktail will increase cytotoxic activities and decrease side effects.

Usage: The authors applied a monoclonal antibody (mAb) cocktail for one target protein with multiple epitopes. They generated anti-CDH17 mAbs recognizing different epitopes on CDH17 (Cadherin-17). CDH17 is expressed in gastric cancer, hepatocellular carcinoma, colorectal cancer, and pancreatic cancer and has limited distribution in normal tissues. For preparation of 3 immunotoxins, Streptavidin-ZAP was mixed with biotinylated mAbs in equimolar concentrations for 30 minutes at room temperature. The study provides data to demonstrate that the cocktail of different epitope-recognizing immunotoxins has synergistic cytotoxic effects on CDH17-expressing cells.

Objective: To evaluate priming, at both nociceptor terminals, the effect of local administration of agents that reverse type I (protein translation) or type II [combination of Src and mitogen-activated protein kinase (MAPK)] priming

Summary: Fentanyl, acting at the -opioid receptor (MOR), induces hyperalgesia and hyperalgesic priming at both the central and peripheral terminal of nociceptors and this is mediated by endoplasmic reticulum Ca2 signaling. Priming in the central terminal is type II, whereas that in the peripheral terminal is type I. Our findings may provide useful information for the design of drugs with improved therapeutic profiles, selectively disrupting individual MOR signaling pathways, to maintain an adequate long-lasting control of pain.

Usage: IB4-SAP was diluted in saline and a dose of 3.2 μg in a volume of 20 μl and administered intrathecally 14 d before experiments
