TLR4 and infection: Ingeneral, infection with two different serotypes elicited a stronger Toll pathwayresponse in Ae. aegypti and this trend was also seen in similarlyinfected Ae. albopictus mosquitoes which suggests that PR DENV-2has either a slower replication rate than PR DENV-1, a titer threshold, or is ableto regulate the mosquito antiviral response.
