    Germinal center B cell development has distinctly regulated stages completed by disengagement from T cell help

    Ting-ting Zhang et al.
    CD40 signaling is necessary to generate the immediate precursors of GC B cells, transition to the BCL6hi follicular state is promoted by a regional and transient diminution of T cell help.

    The transforming growth factor beta signaling pathway is critical for the formation of CD4 T follicular helper cells and isotype-switched antibody responses in the lung mucosa

    Heather D Marshall et al.
    Differentiation of CD4 T cells into CD4 T follicular helper cells during viral infection in mice is promoted by tumor growth factor beta.

    The quantity of CD40 signaling determines the differentiation of B cells into functionally distinct memory cell subsets

    Takuya Koike et al.
    Unveiling a mechanism for the fate decision of B-cell differentiation into two functionally distinct memory B cell subsets.

    Glutamine metabolism modulates azole susceptibility in Trypanosoma cruzi amastigotes

    Peter C Dumoulin et al.
    Trypanosoma cruzi intracellular amastigotes exhibit rapid resistance to azoles, independent of genetic selection, which is dependent on metabolic state and mechanistically distinct from latency.

    Quantitative modeling of the effect of antigen dosage on B-cell affinity distributions in maturating germinal centers

    Marco Molari et al.
    Detailed and inferred model reproduces B-cell affinity distributions measured in mice immunized according to various protocols and explains non-monotonous effects of antigen dosage on maturation.

    Cerebellar nuclei excitatory neurons regulate developmental scaling of presynaptic Purkinje cell number and organ growth

    Ryan T Willett et al.
    The first born excitatory cerebellar nuclei neurons influence the survival of their Purkinje cell partners which stimulate the expansion of granule cells and interneurons to produce functional local circuits.

    Transient inhibition of the ERK pathway prevents cerebellar developmental defects and improves long-term motor functions in murine models of neurofibromatosis type 1

    Edward Kim et al.
    Nf1 is required during early, but not late, cerebellar development to facilitate neuronal lamination, providing a potential therapeutic prevention strategy for NF1-associated developmental abnormalities.

    A bacterial riboswitch class for the thiamin precursor HMP-PP employs a terminator-embedded aptamer

    Ruben M Atilho et al.
    Many bacteria use a tiny riboswitch aptamer to sense the thiamin precursor HMP-PP to regulate the production of another thiamin precursor HET-P to efficiently biosynthesize this essential coenzyme.

    IgM and IgD B cell receptors differentially respond to endogenous antigens and control B cell fate

    Mark Noviski et al.
    Self-reactive B cells downregulate the IgM but not the IgD B cell receptor, and this serves as a critical tolerance mechanism because IgD is less sensitive to bona fide endogenous antigens than IgM.

    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor et al.
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.
