Association between Fcγ receptor IIA, IIIA and IIIB genetic polymorphisms and susceptibility to severe malaria anemia in children in western Kenya
Munde, Elly O.; Okeyo, Winnie A.; Raballah, Evans; Anyona, Samuel B.; Were, Tom; Ong’echa, John M.; Perkins, Douglas J.; Ouma, Collins (BMC Infectious Diseases, 2017-04-20)Background Naturally-acquired immunity to Plasmodium falciparum malaria develops after several episodes of infection. Fc gamma receptors (FcγRs) bind to immunoglobulin G (IgG) antibodies and mediate phagocytosis of opsonized ... -
Feedback-Based, System-Level Properties of Vertebrate-Microbial Interactions
Rivas, Ariel L.; Jankowski, Mark D.; Piccinini, Renata; Leitner, Gabriel; Schwarz, Daniel; Anderson, Kevin L.; Fair, Jeanne M.; Hoogesteijn, Almira L.; Wolter, Wilfried; Chaffer, Marcelo; Blum, Shlomo; Were, Tom; Konah, Stephen N; Kempaiah, Prakash; Ong’echa, John M.; Diesterbeck, Ulrike S.; Pilla, Rachel; Czerny, Claus-Peter; Hittner, James B.; Hyman, James M.; Douglas J. Perkins, Douglas J. (PLOS ONE, 2013-02-20)Background Improved characterization of infectious disease dynamics is required. To that end, three-dimensional (3D) data analysis of feedback-like processes may be considered. Methods To detect infectious disease data ... -
Genetic variation in CSF2 (5q31.1) is associated with longitudinal susceptibility to pediatric malaria, severe malarial anemia, and all-cause mortality in a high-burden malaria and HIV region of Kenya
Kisia, Lily E.; Cheng, Qiuying; Raballah, Evans; Munde, Elly O.; McMahon, Benjamin H.; Hengartner, Nick W.; Ong’echa, John M.; Chelimo, Kiprotich; Lambert, Christophe G.; Ouma, Collins; Kempaiah, Prakasha; Perkins, Douglas J.; Schneider, Kristan A.; Anyona, Samuel B. (Tropical Medicine and Health, 2022-06-25)Plasmodium falciparum infections remain among the leading causes of morbidity and mortality in holoendemic transmission areas. Located within region 5q31.1, the colony-stimulating factor 2 gene (CSF2) encodes granulocyte ... -
Genetic variation in interleukin-7 is associated with a reduced erythropoietic response in Kenyan children infected with Plasmodium falciparum
Kisia, Lily E.; Kempaiah, Prakasha; Anyona, Samuel B.; Munde, Elly O.; Achieng, Angela O.; Ong’echa, John M.; Lambert, Christophe G.; Chelimo, Kiprotich; Ouma, Collins; Perkins, Douglas J; Raballah, Evans (BMC Med Genet., 2019-08-16)Background Severe malarial anemia (SMA) is a leading cause of malaria-related morbidity and mortality in children. The genetic factors that influence development of SMA and inefficient erythropoiesis, a central pathogenic ... -
Haplotype of non-synonymous mutations within IL-23R is associated with susceptibility to severe malaria anemia in a P. falciparum holoendemic transmission area of Kenya
Munde, Elly O.; Raballah, Evans; Okeyo, Winnie A.; Ong’echa, John M.; Perkins, Douglas J.; Ouma, Collins (BMC Infectious Diseases volume, 2017-04-20)Background Improved understanding of the molecular mechanisms involved in pediatric severe malarial anemia (SMA) pathogenesis is a crucial step in the design of novel therapeutics. Identification of host genetic susceptibility ...
