Monoclonal Antibody to CD36 Does Not Inhibit Plasmodium Sporozoite Invasion of HepG2 Cells
| Expt. a | Treatment | Number of EEFsb |
|---|---|---|
| 1 | Control | 249 ± 4 |
| MAb 8A6 | 238 ± 13 | |
| 2 | Control | 714 ± 53 |
| Mab 8A6 | 620 ± 22 |
Experiments 1 and 2 were performed with HepG2 cells (ATCC HB8065; Rockville, MD), plated in DMEM with 10% fetal calf serum in labtek chamber slides, and allowed to grow overnight. Plasmodium berghei sporozoites in medium with or without 100 μg/ml mAb 8A6 were added to HepG2 cells. After 2 h at 37°C, unattached sporozoites were removed, fresh medium was added, and 2 days later cells were fixed and exoerythrocytic forms (EEFs) were visualized with mAb 2E6 (directed against the liver stage of P. berghei) and goat anti-mouse Ig conjugated to horseradish peroxidase.
