Variant-specific immunity to Plasmodium berghei in pregnant mice.
We have investigated the immunological basis of pregnancy-related Plasmodium berghei recrudescence in immune mice with substantial preexisting immunity. Specifically, we examined the relevance of this experimental model to the study of pregnancy-associated malaria (PAM) caused by P. falciparum in women with substantial preexisting protective immunity. We used mice with immunity induced prior to...
متن کاملT cells and protective immunity to Plasmodium berghei in rats.
Experiments were carried out in which unfractionated spleen cells, and T lymphocyte subpopulations characterized by certain experimental criteria, were isolated at various times from rats infected with Plasmodium berghei. By adoptive transfer it was shown that unfractionated spleen cells, and T cells alone, could transfer protection to syngenic recipients as early as 11 days after infection of ...
متن کاملSecreted antibody is required for immunity to Plasmodium berghei.
Infection with Plasmodium berghei is lethal to mice, causing high levels of parasitemia, severe anemia, and death. However, when mice are treated with antimalarial drugs during acute infection, they have enhanced immunity to subsequent infections. With this infection and cure model of immunity, we systematically examined the basis of adaptive immunity to infection using immunodeficient mice. In...
متن کاملChemical attenuation of Plasmodium berghei sporozoites induces sterile immunity in mice.
Radiation and genetic attenuation of Plasmodium sporozoites are two approaches for whole-organism vaccines that protect against malaria. We evaluated chemical attenuation of sporozoites as an alternative vaccine strategy. Sporozoites were treated with the DNA sequence-specific alkylating agent centanamycin, a compound that significantly affects blood stage parasitemia and transmission of murine...
متن کاملThe Impact of Plasmodium Berghei Exposure In-utero on Neurobehavioral Profile in Mice
Introduction: The World Health Organization estimates that about 25 million pregnant mothers are currently at risk for malaria, and that malaria accounts for over 10,000 maternal and 200,000 neonatal deaths per year. The current hypothesis of early life programming supports the premise that many developmental delay and disorders may have their origin In-utero. Therefore, the current study aimed...
