AI Article Synopsis

  • The study aimed to investigate the localization of the signaling protein 14-3-3 in the Schistosoma japonicum parasite.* -
  • Cercariae were collected from infected snails to infect rabbits, and various life stages of the parasite were analyzed using immunofluorescence staining.* -
  • Findings revealed that Sj14-3-3 is primarily located in the tegument, subtegument, muscle, and parenchyma of both adult worms and younger schistosomula, suggesting its importance for future biological studies.*

Article Abstract

Objective: To study the localization of the signaling protein 14-3-3 of Schistosoma japonicum (Sj14-3-3) in the parasite.

Methods: Cercariae were collected from the infected Oncomelania hupensis for the infection of rabbits. Fifteen-day-old schistosomula and adult worms obtained from infected rabbits 15 and 42 days post-infection were used for frozen sections and indirect immunofluorescence staining with monoclonal antibody to rSj14-3-3.

Results: The results showed that the Sj14-3-3 distributed mainly in the tegument, subtegument, muscle, and parenchyma of both adult worms and 15-day-old schistosomula.

Conclusion: The wide distribution and large sites of Sj14-3-3 in the parasite were clearly demonstrated, which established a significant clue for further studies of biologic actions and application of 14-3-3 protein.
