    Single and combined deletions of the NTAL/LAB and LAT adaptors minimally affect B-cell development and function

  • Original language description

    NTAL and LAT are evolutionarily related transmembrane adaptor proteins that are phosphorylated upon immunoreceptor engagement. LAT expression was limited to early B cells, whereas NTAL expression typified mature B cells. Ntal-deficient mice were generated and crossed with Lat-deficient mice. B cells developed in Lat(-/-) Ntal(-/-) double-deficient mice with the same efficiency as in wild-type mice. Upon B-cell antigen receptor cross-linking, Ntal(-/-) B cells exhibited slightly increased Ca(2+) mobilization and proliferation. Ntal-deficient mice had increased levels of natural antibodies and slightly increased humoral response to a T-dependent antigen. Normal titers of serum-specific immunoglobulins were produced in response to a T-cell-independent antigen. NTAL absence did not affect the hypergammaglobulinemia E and G1 that developed in mice with a mutation in tyrosine 136 of LAT. Therefore, NTAL does not play a role in B cells symmetric to the role played by LAT in T cells.

    Jednotlivé a kombinované delece adaptorů NTAL/LAB a LAT minimálně ovlivňují vývoj a funkci B buněk

  • Czech description

    NTAL a LAT jsou evolučně podobné transmembránové adaptorové proteiny, fosforylované během imunoreceptorové signalizace. Exprese LAT byla omezena na časná stádia B lymfocytů, zatímco NTAL byl charakteristický pro zralé B buňky. Ntal-deficientní myši bylyzkříženy s Lat-deficientními myšmi. B buňky se vyvíjely v těchto dvojitě deficientních zvířatech normálně. Po BCR signalizaci vykazovaly Ntal(-/-) B buňky slabě sníženou mobilizaci Ca(2+) a proliferaci. Ntal-deficientní myši měly více přirozených protilátek a slabě zvýšené protilátkové odpovědi na T-dependentní antigen. Absence NTAL neměla vliv na hypergammaglobulinemii E a G1, která se vyvíjí u myší s mutací tyrosinu 136 LAT. NTAL tedy nehraje ve vývoji B lymfocytů podobnou roli jako LAT u T buněk.
