Unasnemab
Based on 1 Customer Validation
Unasnemab (MT-3921) is a humanised IgG1 monoclonal antibody that binds to repulsive guidance molecule A (RGMa). Unasnemab improves locomotor function and promotes neuroregeneration. Unasnemab exerts ameliorative effects on hippocampal neurogenesis impairment and cognitive decline in db/db mice, Streptozotocin (STZ) (HY-13753)-induced type 1 diabetic and bilateral common carotid artery stenosis (BCAS)-induced mice. Unasnemab can be used for the research of spinal cord injury, diabetes-induced neurological impairments.

Biological Activity

RGMA
Unasnemab (48 h) significantly alleviated the reduction in average neurite length of NB-1 human neuronal cells cocultured with Tax-expressing JPX9 cells (a Tax-inducible cell line) in a dose-dependent manner[1].
Unasnemab (0.001-10 μg/mL, 72 h) significantly reversed the increased concentration of neurofilament light chain (NF-L) in the culture medium of NB-1 cells cocultured with PBMCs with HTLV-1-associated myelopathy (HAM) in a dose-dependent manner[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Unasnemab (10 mg/kg, i.p., twice weekly, starting 3 days post-surgery for a total of 9 injections) significantly ameliorates bilateral common carotid artery stenosis (BCAS)-induced pathological changes and cognitive deficits in mice[3].

Animal Model:6-week-old db/db mice (type 2 diabetes model) and STZ-induced type 1 diabetic 8-week-old C57BL/6JJmsSlc mice[2]
-
Dosage:30 mg/kg
-
Administration:i.v., once weekly, 6 weeks
-
Result:Increased the number and density of DCX-positive immature neurons in the hippocampal granular cell layer (GCL), and improved their morphological defects.
Significantly increased the Discrimination Index (DI) in both Novel Object Recognition Test (NORT) and Object Placement Test (OPT) to restore hippocampus-dependent memory.
Showed no significant effects on STZ-induced body weight loss and blood glucose elevation.
-
Animal Model:Adult male C57BL/6J mice (8-10 weeks old) were used to establish the vascular dementia (VaD) model via bilateral common carotid artery stenosis (BCAS)[3]
-
Dosage:10 mg/kg
-
Administration:i.p., twice weekly, starting 3 days post-surgery for a total of 9 injections
-
Result:Reversed the reduction of doublecortin (DCX)-positive immature neurons in the hippocampal granular cell layer (GCL) and subgranular zone (SGZ).
Decreased the number of cleaved caspase-3/DCX double-positive apoptotic cells.
Promoted the survival and maturation of newborn neurons.
Attenuated the loss of cholinergic innervation in the hippocampal dentate gyrus.
Improved cognitive function.
Did not affect cerebral blood flow (CBF) in BCAS mice.
