A well-conserved Plasmodium falciparum var gene shows an unusual stage-specific transcript pattern [PDF]

, 2003
The var multicopy gene family encodes Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) variant antigens, which, through their ability to adhere to a variety of host receptors, are thought to be important virulence factors.

Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

Integrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

Integrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Production and characterization of different types of malaria pigment (hemozoin) and their potential use for screening for hemozoin inhibiting drugs [PDF]

, 2012
Tese de mestrado. Biologia (Microbiologia Aplicada). Universidade de Lisboa, Faculdade de Ciências, 2012Malarial pigment, hemozoin, appears to modulate the immune system, however it remains controversial if it has stimulatory or inhibitory effects ...

Profiling invasive Plasmodium falciparum merozoites using an integrated omics approach [PDF]

, 2017
The symptoms of malaria are brought about by blood-stage parasites, which are established when merozoites invade human erythrocytes. Our understanding of the molecular events that underpin erythrocyte invasion remains hampered by the short-period of time

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

Integrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

Integrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Functional profiles of orphan membrane transporters in the life cycle of the malaria parasite

Nature Communications, 2016
The functions of many putative membrane transport proteins of malaria parasites are unknown. Here, Kenthirapalan et al. use mutant strains carrying targeted gene deletions to study the functions of 35 such proteins during the life cycle of Plasmodium ...

Structural Basis for Trivalent Cross‐Linking of a Patient‐Derived IgE Antibody by the Major Peanut Allergen Ara h 2.0201

Allergy, EarlyView.
Graphical The crystal structure of a major peanut allergen Ara h 2.0201 in a complex with a human‐derived IgE Fab fragment has been determined. The immunocomplex shows the trivalent binding of Fabs, creating a cross‐linked structure effective in the formation of large complexes on the surface of effector cells. Hydroxylation of proline has implications
