    TRPM4 has recently been described as a calcium-activated nonselective (CAN) cation channel that mediates membrane depolarization. However, the functional importance of TRPM4 in the context of calcium (Ca2+) signaling and its effect on cellular responses are not known. Here, the molecular inhibition of endogenous TRPM4 in T cells was shown to suppress TRPM4 currents, with a profound influence on receptor-mediated Ca2+ mobilization. Agonist-mediated oscillations in intracellular Ca2+ concentration ([Ca2+]i), which are driven by store-operated Ca2+ influx, were transformed into a sustained elevation in [Ca2+]i. This increase in Ca2+ influx enhanced interleukin-2 production. Thus, TRPM4-mediated depolarization modulates Ca2+ oscillations, with downstream effects on cytokine production in T lymphocytes.

    All links from this record

    • Related Articles

      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.

    • Compound (MeSH Keyword)

      PubChem chemical compound records that are classified under the same Medical Subject Headings (MeSH) controlled vocabulary as the current articles.

    • 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.
