Key Points
- This research aims to investigate the role of T cells in the immunopathogenesis of myocarditis, particularly focusing on autoimmunity.
- Examined the role of gammadelta+ T cells in myocarditis model using BALB/c and C57Bl/6 mice.
- Investigated the up-regulation of CD1d in infected myocytes and associated immune signaling.
- Analyzed the adaptive immune response modulation toward either Th1 or Th2 phenotypes based on T cell responses.
- Vgamma4+ T cells in BALB/c mice produced IFNgamma, indicating a Th1 response; their recognition of CD1d was confirmed.
- Vgamma1+ T cells in C57Bl/6 mice released IL-4, leading to a Th2 response; CD1d ligand remains unknown.
- Infection-associated signaling through double-stranded RNA and TNFalpha was necessary for CD1d up-regulation.
Structured PICO
PPopulationBALB/c and C57Bl/6 mice models of Coxsackievirus-induced myocarditis
Gammadelta+ T cells play a crucial role in determining disease susceptibility and modulating the adaptive immune response in Coxsackievirus-induced myocarditis.
