Abstract
Rabies is a neglected disease caused by a neurotropic Lyssavirus, transmitted to humans predominantly by the bite of infected dogs. Rabies is preventable with vaccines or proper post_exposure prophylaxis (PEP), but it still causes about 60,000 deaths every year. No cure exists after the onset of clinical signs, and the case_fatality rate approaches 100% even with advanced supportive care. Here, we report that a combination of two potent neutralizing human monoclonal antibodies directed against the viral envelope glycoprotein cures symptomatic rabid mice. Treatment efficacy requires the concomitant administration of antibodies in the periphery and in the central nervous system through intracerebroventricular infusion. After such treatment, recovered mice presented good clinical condition, viral loads were undetectable, and the brain inflammatory profile was almost normal. Our findings provide the unprecedented proof of concept of an antibody_based therapeutic approach for symptomatic rabies.

                    [description_short] => 
Rotarod provides an easy way to test the motor activity in rodents (mouse or rat) - an ideal solution for studying central nervous system damage, disease effects on motor activity, drugs administration, fatigue resistance, etc. Now even easier to use! The new touchscreen graphic user interface allows clear visualization of timing and speed for each lane. Change modes, adjust speed, and create protocols right from the main screen for greater flexibility with maximum functionality and usability

The Four Plates Test is an exclusivity from BIOSEB!
The Aron test allows a quick characterization of putative anxiolytics compounds in naïve animals. A must for studying anxiety, drug screening and phenotyping.
