Figure 3. Atgl^−/− neutrophils accumulate TG-associated 18:1, 18:2, and 20:4.

Lipids of peritoneal lavage cells, 1 d post-thioglycolate injection, were extracted, and concentrations of TGs, TCs, FC, and CEs were determined by enzymatic assays. Data are shown as means + sem (n = 5). FA composition of the most abundant TG (B), PC (C), and phosphatidylethanolamine (PE) (D) species (abundance >3%) was determined by LC/ESI-MS. Data are presented as means + sem of absolute (insets) and relative values (n = 4–5). *P < 0.05; **P ≤ 0.01; ***P ≤ 0.001.
