Immunoblot analysis of LDLr protein levels in cell lysates from infected HFF and H9c2 cells using LDLr specific monoclonal antibodies demonstrated that HFF and H9c2 cells incubated with T. cruzi had a two-fold increase in LDLr protein levels within 1h post-infection (p.i.)(Figure 1A and B). Here, LDLR is linked to infection.
