2018 Targeting Trends Review

Souza GMPR, Kanbar R, Stornetta DS, Abbott SBG, Stornetta RL, Guyenet PG (2018) Breathing regulation and blood gas homeostasis after near complete lesions of the retrotrapezoid nucleus in adult rats. J Physiol 596(13):2521-2545. doi: 10.1113/JP275866

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.

Usage: 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.

Hoffmann RM, Crescioli S, Thurston DE, Karagiannis SN (2018) Development and evaluation of T-Zap: a novel antibody-drug conjugate for the treatment of Her2 positive breast cancer. Cancer Res 78:LB-001. doi: 10.1158/1538-7445.AM2018-LB-001 PMID: 909090

Objective: Develop and Evaluate a novel ADC (T-Zap) for breast cancer.

Summary: Binding to target cells of T-Zap was confirmed. Comparison of T-Zap efficacy in breast cancer cell lines with and without resistance against trastuzumab showed a trend for higher efficacy of cell killing by T-Zap in trastuzumab resistant cells compared to T-DM1. Toxicity assays revealed no impact of T-Zap on cell viability in immune cells.

Usage: T-ZAP was made using Biotinylated monoclonal antibody trastuzumab mixed with Streptavidin-ZAP.

Objective: To investigate the effectiveness and mechanism of theChinese herbal formula Sini Tang (SNT) in heart failure after myocardial infarction in rats.

Summary: The Chinese herbal formula SNT could improve left ventricular systolic function in heart failure after myocardial infarction.

Usage: Western blot.

Harvey BP, Cohen-Solal J, Kaymakcalan Z (2018) SAT0058 Adalimumab: TNF complexes are cleared more efficiently by human osteoclasts than those with etanercept through FCG-receptor binding and internalisation. Ann Rheum Dis 77:893. EULAR 2018, Amsterdam, The Netherlands doi: 10.1136/annrheumdis-2018-eular.3804

Objective: To determine whether Fc-gamma receptor (FcgR)-mediated internalization of the biologic:TNF complexes is a contributing mechanism responsible for the difference in effectiveness between ADA and ETN in preventing TNF- enhanced OCgenesis.

Summary: Human osteoclast  (OC) precursors can bind and internalise ADA:TNF complexes more efficiently than ETN:TNF complexes. In addition, this process is partially mediated through FcgRII.

Usage: FcgR-mediated nternalization was assessed by monitoring a reduction in OC survival in response to preformed bio- logic: TNF complexes (25:1 ratio) bound with FabFC-ZAP human ± FcgR blocking antibodies.

Sakamoto A, Kato K, Hasegawa T, Ikeda S (2018) An agonistic antibody to EPHA2 exhibits antitumor effects on human melanoma cells. Anticancer Res 38:3273-3282. doi: 10.21873/anticanres.12592

Objective: Investigate the therapeutic potential of antibody to EPHA2 against melanoma in vitro.

Summary: Observations indicate a promising role for EPHA2 as a target in antibody treatments for melanoma, and demonstrate the potential therapeutic effects of an agonistic antibody to EPHA2.

Usage: A375 cells were plated into a flat-bottom, 96-well plate (2,000 cells per well) and incubated for 4 days at 37˚C. Cell suspension included different concentrations of Mab-ZAP, along with either anti-EPHA2 mAb (SHM16, SHM17, or SHM20 at 2 μg/ml final concentration), or a control IgG1 mAb (2 μg/ml final concentration).

Cogent Biol 4(1):1469387. doi: 10.1080/23312025.2018.1469387

Objective: To engineer elastic properties into a TNFalpha antibody.

Summary: The results presented in this report with an anti-TNFα ELP mAb are a foundation for building on a new generation of fusion ELP mAbs, or other formats, that are stable, active, responsive to cues in local environment, and, with the FcRn mutation, cleared rapidly from circulation. More detailed studies are warranted to identify the appropriate ELP sequences for IA delivery, calculate residence time in the IA space, and demonstrate pharmacodynamics effect of the ELP-fusion protein.

Usage: Fab-ZAP human was mixed with anti-TNFα-ELP fusion monoclonal.
