Changes in b cell populations and Merozoite surface protein-1-specific memory b cell responses after prolonged absence of detectable p. falciparum infection
Ayieko, Cyrus; Maue, Alexander C.; Jura, Walter G. Z. O.; Noland, Gregory S.; Ayodo, George; Rochford, Rosemary; John, Chandy C. (PLOS, 2013-05)Clinical immunity to malaria declines in the absence of repeated parasite exposure. However, little is known about how B cell populations and antigen-specific memory B cells change in the absence of P. falciparum infection. ... -
Decline in childhood iron deficiency after interruption of malaria transmission in highland Kenya1–3
Frosch, Anne EP; Ondigo, Bartholomew N; Ayodo, George; Vulule, John M; John, Chandy C.; Cusick, Sarah E (AJCN, 2014-07-30)Background: Achieving optimal iron status in children in malariaendemic areas may increase the risk of malaria. Malaria itself may contribute to iron deficiency, but the impact of an interruption in malaria transmission ... -
Decrease in numbers of naive and resting B cells in HIV-infected Kenyan adults leads to a proportional increase in total and Plasmodium falciparum–specific atypical memory B cells
Frosch, Anne E.; Odumade, Oludare A.; Taylor, Justin J.; Ireland, Kathleen; Ayodo, George; Ondigo, Bartholomew; Narum, David L.; Vulule, John; John, Chandy C. (The American Association of Immunologists, Inc., 2017-05-19)Human immunodeficiency virus type 1 (HIV-1) infection is associated with B cell activation and exhaustion, and hypergammaglobulinemia. How these changes influence B cell responses to coinfections such as malaria is poorly ... -
Decreased prevalence of anemia in highland areas of low malaria transmission after a 1-Year interruption of transmission
Noland, Gregory S.; Ayodo, George; Abuya, Jackson; Hodges, James S.; Rolfes, Melissa A. R.; John, Chandy C. (Oxford University Press, 2011-11-03)Background. Malaria control campaigns have reduced malaria transmission to very low levels in many areas of Africa. Yet the extent to which malaria interruption or elimination might decrease the prevalence of anemia in ... -
The Plasmodium falciparum antigen MB2 induces interferon-γ and interleukin-10 responses in adults in malaria endemic areas of Western Kenya
Ochola, Lyticia A; Ng’wena, Gideon M; Noland, Gregory S; Ondigo, Bartholomew N; Ayodo, George; John, Chandy C. (PMC, 2013)Background: MB2 is a novel Plasmodium falciparum antigen of unknown function expressed in pre-erythrocytic and blood stages of infection in the human host. Interferon-gamma (IFN-γ) and interleukin (IL)-10 responses to ... -
Standardization and validation of a cytometric bead assay to assess antibodies to multiple Plasmodium falciparum recombinant antigens
Ondigo, Bartholomew N.; Park, Gregory S.; Gose, Severin O.; Ho, Benjamin M.; Ochola, Lyticia A; Ayodo, George; Ofulla, Ayub V.; John, Chandy C. (BioMed Central Ltd, 2012-12-21)Background Multiplex cytometric bead assay (CBA) have a number of advantages over ELISA for antibody testing, but little information is available on standardization and validation of antibody CBA to multiple Plasmodium ... -
Successful global health research partnerships: What makes them work?
John, Chandy C.; Ayodo, George; Musoke, Philippa (The American Society of Tropical Medicine and Hygiene, 2016-01)There are many successful global health research partnerships, but little information is available about what makes them successful. We asked 14 research colleagues from Uganda, Kenya, and the United States who have extensive ...
