Effect of high temperature on Aedes albopictus cells infected with Mayaro virus

RESUMO

the multiplication of Mayaro virus in Aedes albopictus cells was drastically inhibited after incubation at 37-C. The effect of short-term exposure of infected cells to high temperatures (heat shock) produced a preferential translation of the heat shock messengers when compared to the viral mRNAs. When cells were shifted back to 28-C (the optimum growth temperature for Aedes albopictus cells), preferential translation of viral mRNA occurred. Although the infected cells were programmed for preferential translation of viral messengers, the therminal treatment was able to shif the translational machinery towards synthesis of heat shock proteins
