- Immunology
- Infectious Diseases
Background
- Experimental cerebral malaria is induced in mice infected with Plasmodium berghei ANKA.
- Understanding the role of inflammatory leukocytes in the brain is crucial for studying malaria pathology.
- Isolation of these cells allows for detailed analysis of their characteristics and behavior.

Purpose of Study
- To develop a reliable method for isolating leukocytes from the brain.
- To quantify and characterize the inflammatory response during malaria infection.
- To enhance understanding of the immune mechanisms involved in cerebral malaria.
Methods Used
- Mice are infected with Plasmodium berghei ANKA via injection of parasitized red blood cells.
- Intraoral perfusion is performed to remove circulating cells from malaria-infected mice.
- Brain tissue is harvested and digested with enzymes to isolate leukocytes.
- Multicolor flow cytometry is conducted for immunophenotyping the isolated cells.
Main Results
- The method successfully isolates adherent inflammatory leukocytes from brain blood vessels.
- Flow cytometry analysis reveals the percentage and absolute numbers of leukocytes migrating to the brain.
