The Development Of Humoral And Cellular Responses To Plasmodium Falciparum Malaria In The Hypoendemic Peruvian Amazon And Potential Clinical Protection, Eva Helen Clark

All ETDs from UAB

Each year 300-500 million cases of Plasmodium falciparum malaria occur, leading to more than 1 million deaths. In high malaria transmission regions, development of immunity from severe infection requires 2-10 years of persistent parasitemia. This delay has been attributed to difficulties in the development of protective humoral responses. Indeed, anti-malarial antibody responses tend to be short-lived, and immunologic memory seems to be dysfunctional in high-transmission regions. In contrast, in the low-transmission Peruvian Amazon >60% of infections are asymptomatic, suggesting that clinical immunity occurs despite low parasite exposure. To analyze more precisely the naturally-acquired humoral responses to malarial antigens and their …
