TLR4 and infection: Figure 5 illustrates TLR2 and TLR4 expression after infection with each L. (V.)braziliensis isolate. Median TLR2 and TLR4 expression levels are represented as MFI. While monocytes from DL patients expressed elevated levels of TLR2 and TLR4 following infection with a DL isolate compared to CL: 1425 (274-2350) and 2384 (270-3542) versus 853 (91-1633) and 1544 (235-3028), respectively (P<0.05), similar expression was observed for both receptors when DL or CL isolates were used to infect CL monocytes (P>0.05).
