Title: Establishment of minimal positive-control conditions to ensure brain safety during rapid development of emergency vaccines
  • Document date: 2017_8_22

    Snippet: How to apply the lipopolysaccharide (LPS) positive-control protocol to verify vaccine safety at the blood-brain barrier (BBB). Based on the results of our experiments, we have established a positive-control protocol for determining vaccine safety at the BBB. Salmonella enterica-derived LPS and vaccine are intraperitoneally injected into 7-week-old ICR mice (1.0 mg LPS/4 mL PBS/kg body weight) and brain hemispheres are removed after 4 h. The mRNA .....
    Document: How to apply the lipopolysaccharide (LPS) positive-control protocol to verify vaccine safety at the blood-brain barrier (BBB). Based on the results of our experiments, we have established a positive-control protocol for determining vaccine safety at the BBB. Salmonella enterica-derived LPS and vaccine are intraperitoneally injected into 7-week-old ICR mice (1.0 mg LPS/4 mL PBS/kg body weight) and brain hemispheres are removed after 4 h. The mRNA is extracted, followed by quantitative real-time polymerase chain reaction (PCR) using zonula occludens-1 (ZO-1), occludin, and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) primers. By comparing the tight junction mRNA levels of the vaccine-injected group with those of the LPS-injected group, the potential danger to the BBB of the vaccine is evaluated.
