Abstract

Pro-inflammatory cytokines induced by glycosylphosphatidylinositols (GPIs) of Plasmodium falciparum contribute to malaria pathogenesis and hence, the naturally acquired anti-GPI antibody thought to provide protection against severe malaria (SM) by neutralizing the stimulatory activity of GPIs. In previous studies, the anti-GPI antibody levels increased with age in parallel with the development of acquired immunity, and high levels of anti-GPI antibodies were associated with mild malaria (MM) cases. In the present study, the relationship between the levels of pro-inflammatory cytokines and anti-GPI IgG antibody responses, parasitemia, and the clinical outcomes were evaluated in SM and mild malaria (MM) patients. Sera from a total of 110 SM and 72 MM cases after excluding of ineligible patients were analyzed for the levels of anti-GPI antibodies, IgG subclasses, and cytokine responses by ELISA. While the total anti-GPI antibody levels were similar in overall SM and MM groups, they were significantly higher in surviving SM patients than in fatal SM cases. In the case of cytokines, the TNF-α and IL-6 levels were significantly higher in SM compared to MM, whereas the IL-10 levels were similar in both groups. The data presented here demonstrate that high levels of the circulatory pro-inflammatory, TNF-α, and IL-6, are indicators of malaria severity, whereas anti-inflammatory cytokine IL-10 level does not differentiate SM and MM cases. Further, among SM patients, relatively low levels of anti-GPI antibodies are indicators of fatal outcomes compared to survivors, suggesting that anti-GPI antibodies provide some level of protection against SM fatality.

17. Comparison of Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry and Molecular Biology Techniques for Identification of Culicoides(Diptera: Ceratopogonidae) Biting Midges in Senegal

Abstract

ABSTRACTBiting midges of the genus Culicoidesare implicated as vectors for a wide variety of pathogens. The morphological identification of these arthropods may be difficult because of a lack of detailed investigation of taxonomy for this species in Africa. However, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) profiling is efficient for arthropod identification at the species level. This study established a spectrum database of Culicoidesspp. from Senegal using MALDI-TOF. Identification of Culicoidesinsects to the species level before mass spectrometry was performed on the basis of morphological characters. MALDI-TOF MS reference spectra were determined for 437 field-caught Culicoidesof 10 species. The protein profiles of all tested Culicoidesrevealed several peaks with mass ranges of 2 to 20 kDa. In a validation study, 72 Culicoidesspecimens in the target species were correctly identified at the species level with a similarity of 95 to 99.9%. Four Culicoidesprotein profiles were misidentified. Nevertheless, six SuperSpectra (C. imicola, C. enderleini, C. oxystoma, C. kingi, C. magnus, and C. fulvithorax) were created. Abdomens of midges were used to amplify and sequence a portion of the mitochondrial cytochrome oxidase I gene (COI). The results obtained using the MALDI-TOF MS method were consistent with the morphological identification and similar to the genetic identification. Protein profiling using MALDI-TOF is an efficient approach for the identification of Culicoidesspp., and it is economically advantageous for approaches that require detailed and quantitative information of vector species that are collected in field. The database of African CulicoidesMS spectra created is the first database in Africa. The COI sequences of five Culicoidesspecies that were previously noncharacterized using molecular methods were deposited in GenBank.
