Human phagocyte interactions with the Lyme disease spirochete
Infection and Immunity
|November 1, 1984
Summary
Human immune cells, polymorphonuclear leukocytes and monocytes, effectively engulf and destroy Lyme disease spirochetes. Antibodies enhance this process but are not strictly required for phagocytosis.
Area of Science:
- Immunology
- Microbiology
- Infectious Diseases
Background:
- Lyme disease is caused by Borrelia burgdorferi, a spirochete transmitted by ticks.
- Understanding the host immune response is crucial for developing effective treatments.
Purpose of the Study:
- To investigate the interaction between human phagocytic cells and Lyme disease spirochetes.
- To determine the role of antibodies in phagocytosis of the spirochete.
Main Methods:
- Incubating human polymorphonuclear leukocytes and monocytes with Lyme disease spirochetes.
- Utilizing microorganisms adhered to plastic or glass surfaces for incubation.
Main Results:
- Both polymorphonuclear leukocytes and monocytes demonstrated efficient phagocytosis of spirochetes.
- These phagocytic cells were also capable of killing the ingested spirochetes.
- Antibodies were found to facilitate phagocytosis but were not essential for the process.
Conclusions:
- Human polymorphonuclear leukocytes and monocytes are key players in combating Lyme disease spirochetes.
- The innate immune system can effectively clear spirochetes, with or without antibody assistance.
