      • It Ain’t Over ‘Til the Fat Lady Sings

        The antiatherogenic drug nicotinic acid (niacin) has antidyslipidemic effects independent of free fatty acid suppression mediated by its receptor HCA2 (GPR109A) (Lauring et al., this issue).

      • Niacin Lipid Efficacy Is Independent of Both the Niacin Receptor GPR109A and Free Fatty Acid Suppression

        GPR109A is not the target mediating niacin’s lipid efficacy and the free fatty acid hypothesis does not explain niacin’s mechanism of action.

ONLINE COVER Immunology, Meet Engineering. As translational immunology delves deeper into mechanism, there is a desire for quantitative, design-based bioengineering tools to aid in not only understanding human disease, but also treating it. In this issue of Science Translational Medicine, Swartz et al. discuss the budding relationship between engineers and immunologists by reviewing various opportunities for collaboration in the emerging field of "immunoengineering." In one vaccine-related example depicted on the cover, nanoparticles carrying antigen (red, orange, and blue) can be taken up by antigen-presenting cells in target tissues before traveling through lymphatic vessels (in green) to the lymph node.
