  Evaluation Summary:

  In this study, the authors highlight a role for de novo biosynthesis of Poly-unsaturated Fatty Acids and the consequence effect of these metabolites on the production of arachidonic acid. The increased bio-availability of arachidonic acid seemingly promotes mycobacterial growth whilst inhibition of arachidonic acid formation, and its resultant downstream eicosanoid products, affect macrophage function but somewhat surprisingly do not affect growth of M. tuberculosis in macrophages or in mice. The uptake of the different classes of fatty acids in axenic culture as well as in macrophages is explored and the authors demonstrate that the Mce1 transporter is largely responsible for their uptake during in vitro growth but only plays a partial role in their uptake during growth of the pathogen in host cells. This work will be of interest to bacteriologists and those studying infectious diseases.

Protein kinase Cδ is essential for the IgG response against T-cell-independent type 2 antigens and commensal bacteria

• Curated by eLife

  Evaluation Summary:

  The unexpected key finding is that T-cell-independent B cell activation engages the intracellular protein kinase PKC-delta to induce the necessary machinery of altered gene transcription culminating in IgG production. The methodology and the experimental setting are well-controlled, although how exactly B-cell stimulation by T-cell-independent antigens triggers PKC-delta remains to be elucidated.
