Although viral protein expression was unaffected, indicating that virus entry occurs, Rab27b and Rab27a co-depletion led to a 73.09% (± 8.82%) reduction in the release of infections OROV particles, an effect that was stronger compared to the individual depletion of the Rab27 isoforms (Fig 2D). The gene discussed is RAB27B; the disease is infection.
