    Abstract

    Malaria that is caused by Plasmodium falciparum is a significant global health problem. Genetic characteristics of the host influence the severity of disease and the ultimate outcome of infection, and there is evidence of coevolution of the plasmodium parasite with its host. In humans, pyruvate kinase deficiency is the second most common erythrocyte enzyme disorder. Here, we show that pyruvate kinase deficiency provides protection against infection and replication of P. falciparum in human erythrocytes, raising the possibility that mutant pyruvate kinase alleles may confer a protective advantage against malaria in human populations in areas where the disease is endemic.

      Related information

      • Related Citations
        Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.
      • Gene
        Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.
      • Gene (GeneRIF)
        Gene records that have the current articles as Reference into Function citations (GeneRIFs). NLM staff reviewing the literature while indexing MEDLINE add GeneRIFs manually.
      • Gene (OMIM)
        Gene records associated with Online Mendelian Inheritance in Man (OMIM) records that cite the current articles in their reference lists.
      • HomoloGene
        HomoloGene clusters of homologous genes and sequences that cite the current articles. These are references on the Gene and sequence records in the HomoloGene entry.
      • Nucleotide (RefSeq)
        NCBI nucleotide Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.
      • Nucleotide (Weighted)
        Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.
      • OMIM (calculated)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as references in the light bulb links within or in the citations at the end of the OMIM record. The references available through the light bulb link are collected using the PubMed related articles algorithm to identify records with similar terminology to the OMIM record.
      • OMIM (cited)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as reference cited at the end of the OMIM record.
      • Protein (RefSeq)
        NCBI protein Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.
      • Protein (Weighted)
        Protein records associated with the current articles through related Gene database records. These are the related sequences on the Gene record that are added manually by NCBI.
      • Substance (MeSH Keyword)
        PubChem chemical substance (submitted) records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.
      • Taxonomy via GenBank
        Taxonomy records associated with the current articles through taxonomic information on related molecular database records (Nucleotide, Protein, Gene, SNP, Structure).
      • UniGene
        UniGene clusters of expressed sequences that are associated with the current articles through references on the clustered sequence records and related Gene records.
      • GEO Profiles
        Gene Expression Omnibus (GEO) Profiles of molecular abundance data. The current articles are references on the Gene record associated with the GEO profile.
      • Cited in PMC
        Full-text articles in the PubMed Central Database that cite the current articles.
