MOG (35-55), human, a constituent of central nervous system myelin, is distinguishable from mMOG (35-55) due to a proline-to-serine substitution at position 42. It possesses immunogenic properties and is partially cross-reactive with mMOG35–55. However, MOG (35-55), human does not induce encephalitogenic effects, and only elicits minimal clinical signs of EAE (experimental autoimmune encephalomyelitis) in comparison to the rodent peptide.

MOG peptide (35-55), a myelin oligodendrocyte glycoprotein (MOG) fragment spanning amino acids 35 to 55, selectively stimulates CD4+ T cell expansion and induces experimental autoimmune encephalomyelitis (EAE) in animal models [1] [2] [3].

R 715, a bradykinin B1 receptor antagonist, inhibits contractions in isolated human umbilical cords that express bradykinin B1 receptors (pA2 = 8.49). When administered at doses of 200, 400, and 600 µg/kg, R 715 enhances latency to tail withdrawal in the tail-flick test for diabetic neuropathy mouse models induced by streptozotocin (STZ), signaling potential analgesic properties. Furthermore, at a 1 mg/kg per day dosage, it mitigates symptoms in a mouse model of experimental autoimmune encephalomyelitis (EAE) induced by MOG35-55 antigen peptide, such as reducing hind limb weakness and paralysis, improving gait symmetry, and decreasing spinal inflammation, neuron demyelination, and lesion monocyte invasion. Additionally, R 715 at 0.01 nmol/animal, administered intracerebroventricularly (i.c.v.), lowers mean arterial blood pressure and increases heart rate in spontaneously hypertensive rats, indicating cardiovascular effects.
