IgG1 and IgG2 antibody responses to Plasmodium falciparum exoantigens correlate inversely and positively, respectively, to the number of malaria attacks

IgGl and IgG2 antibody responses to Plasmodium falciparum

In Manarintsoa, near Antananarivo, Madagascar, two groups of patients were defined in terms of malaria clinical immune status: Group MA+ consisted of 36 patients who suffered from between one to four malaria attacks (MA) during the 20-week study, and Group MAwho comprised of 48 persons who did not have any malaria attacks during this time. In group MA+, IgM and IgG antibody levels to Plasmodium...

The Use of Crude Plasmodium falciparum Antigens for Comparison of Antibody Responses in Patients with Mild Malaria vs. Cerebral Malaria

Background: Cerebral malaria (CM) is one of the major causes of death in African populations infected with Plasmodium falciparum. Only 1% of infected subjects develop CM. The reasons for these differences are not fully understood, but it is likely that the host humoral response against blood-stage antigens plays a role in protection from malaria, although the precise targets and mechanisms medi...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

Effect of placental malaria and HIV infection on the antibody responses to Plasmodium falciparum in infants.

BACKGROUND Placental malaria (PM) and maternal infection with human immunodeficiency virus (HIV) type 1 have been shown to affect infant morbidity and immune responses to Plasmodium falciparum. We studied the effects of PM and HIV infection on the antimalarial antibody responses and morbidity outcomes of infants throughout the first year of life. METHODS A total of 411 Kenyan infants who were...
