CYSLTR1 and infection: To assess the effect of CysLTR1 blockade in the severity of infection, an inoculum of 1 × 106 P. brasiliensis was injected into A/J and B10.A mice treated or not with MTL during 3 days (10 mg/kg/day by the oral route) starting 24 h before infection and fungal burdens measured 48 h after infection.
