Implication
Does not support myosin tolerization for acute Chagas myocarditis; leaves open parasite-specific immunity as dominant driver for human validation.
Structured PICO
Does myosin tolerization prevent cardiac inflammation in mice with acute Trypanosoma cruzi infection?
P
Population
Mice susceptible to Trypanosoma cruzi infection and autoimmune myocarditis
I
Intervention
Injection of myosin-coupled splenocytes (myosin tolerization) or T. cruzi-coupled splenocytes
C
Comparator
Untreated infected mice or mice immunized with purified myosin
O
Outcome
Cardiac inflammation (myocarditis) and cardiac parasitosissurrogate
Myosin-specific autoimmunity is not essential for cardiac inflammation in acute Trypanosoma cruzi infection, whereas parasite-specific cell-mediated immunity is crucial for myocarditis and survival.
