  "summary": "Immune cells rely on exogenous fatty acids (FA) for membrane synthesis, bioenergetics and signalling, yet current approaches cannot accurately quantify physiological FA uptake in vivo. Here, we use cyclopropene-tagged fatty acids (cpFA) that, unlike existing FA-uptake tools, are taken up by physiologically relevant mechanisms. We measure FA uptake at single-cell resolution in vivo and uncover a…",
