J Clin Invest e156955. doi: 10.1172/jci156955

Objective: To engineer targeted antibody conjugates directed against the cardiac conduction system (CCS) to allow visualization of the CCS in vivo.

Summary: Accidental injury to the CCS, a specialized set of cells embedded within the heart and indistinguishable from the surrounding heart muscle tissue, is a major complication in cardiac surgeries. They generated a fully human monoclonal Fab (hCNTN2) that targets the CCS with high specificity.

Usage: Streptavidin-ZAP was reacted with biotinylated hCNTN2 Fab to create hCNTN2-SAP. 100 ug of either hCNTN2-SAP and control-SAP were injected into wild-type mice with a single tail-vein injection and hearts were harvested after 2 days.

Objective: Review recent advances in protein nano-carriers that are from ground-up design recombinant proteins.

Summary: Nanocarriers with a size range of 10-200 nm have emerged as platforms with significant potential for efficient drug delivery via a wide variety of administration routes. To develop nanocarriers for drug delivery, the following functionalities should be achieved. Nanocarriers encapsulate drugs with high loading efficiency and maintain stability in vivo to protect drugs from degradation and prolonged in vivo circulation in blood or residence time in other tissues help improve the fraction of drug-loaded nanocarriers that reach the target site or cells. The Design functionalization, and therapeutic application of protein nanocarriers will be reviewed.

Usage: Saporin is used as the molecular cargo for Protein-Glycan Nanocarriers.

ACS Pharmacol Transl Sci 5(9):791-802. doi: 10.1021/acsptsci.2c00069 PMID: 36110372

Objective: The endocannabinoid system is involved in the control of learning, memory, and neuroinflammatory processes and plays a role in neurodegeneration, such as in Alzheimer’s disease (AD). The objective was to study the roles of cannabinoid receptors in the regulation of neuroinflammation.

Summary: Selective agonists and antagonists to the cannabinoid receptors CB1 and CB2 were studied for their binding to G-proteins after specific lesioning of the basal forebrain cholinergic neurons (BCFN) using 192-IgG-SAP. These neurons are the same cholinergic pathways that are lost in the early stages of Alzheimer’s disease (AD). In their study, an increase of microglia immunoreactivities (GFAP and Iba-1) and decrease of astrocyte immunoreactivities were seen which indicate microglia-mediated neuroinflammation. In cortical BFCN projection areas, CB1 receptor binding to Gi/o-proteins was upregulated and at the injection site, the area that showed the highest increase of microglia, only slight CB2 binding to Gi/o-proteins were detected. Dose: Rats received 135 ng/μLof 192IgG-saporin (1μL/hemisphere; 0.25μL/min).

Objective: To determine whether reciprocal interaction of basal forebrain cholinergic neurons (BFCN) impact neurotrophin availability and affect cortical neuronal markers.

Summary: There is a neuroprotective role of cholinergic neurotransmission in the adult, fully-differentiated cortex.

Usage: Immunolesioned BFCN projecting mainly to the cortex with 192-IgG-SAP (bilateral 0.5 ug/ul; 1.0 ul/hemisphere) in 2.5 month-old Wistar rats.

Objective: To determine whether a catalytic action of iron porphyrin compounds would be related to their stimulation of insulin signaling and glucose uptake in C2C12 myotubes.

Summary: Findings suggest that iron porphyrin compounds with both peroxynitrite decomposition activity and peroxidase activity can stimulate insulin signaling and glucose transport in skeletal muscle cells.

Objective: Using Saporin-containing iron oxide nanoparticles to selectively eliminate cancer cells.

Summary: Saporin [PR-01] is trapped inside of nanoparticle using iron oxide and polymers that opens and delivers payload dependent on its pH enviroment. The nanoparticle-SAP was then treated on healthy and cancerous cells and tested for its selectivity in killing cancerous cells and its internalization efficiency.

Usage: An iron oxide nanoparticle is coated in an amphiphilic polymer, then linker groups are attached to the polymer coating which then bind saporin molecules to the nanoparticle. In the cytotoxicity assays, SK-Br-3 cells are treated with this nanoparticle at concentrations of 25, 37.5, and 50 μg/mL. In internalization assays, SK-Br-3 cells are treated with fluorescently-labeled saporin-nanoparticles and assessed on fluorescence intensity.
