Abstract

Lysosomal acid lipase (LAL) is a key enzyme in the metabolic pathway of neutral lipids, whose deficiency (LAL-D) induces the differentiation of myeloid lineage cells into myeloid-derived suppressor cells (MDSCs), which promotes tumor growth and metastasis. This protocol provides detailed procedures for assessment of various LAL biochemical and physiological activities in Ly6G+ and CD11c+ MDSCs, including isolation of Ly6G+ and CD11c+ cells from the bone marrow and blood of mice, assays of LAL-D-induced cellular metabolic and mitochondrial activities, assessment of LAL-D-induced pathogenic immunosuppressive activity and tumor stimulatory activity. Pharmacological inhibition of the LAL activity was also described in both murine myeloid cells and human white blood cells.

Ly6G+和CD11c+髓源性抑制细胞溶酶体酸性脂肪酶的特征。
溶酶体酸性脂肪酶(LAL)是中性脂质代谢途径中的一种关键酶,缺乏这种酶(LAL-D)会诱导髓系细胞分化为髓源性抑制细胞(MDSCs),从而促进肿瘤生长和转移。该方案提供了评估 Ly6G+ 和 CD11c+ MDSCs 中各种 LAL 生化和生理活性的详细步骤,包括从小鼠骨髓和血液中分离 Ly6G+ 和 CD11c+ 细胞、检测 LAL-D 诱导的细胞代谢和线粒体活性、评估 LAL-D 诱导的致病性免疫抑制活性和肿瘤刺激活性。此外,还描述了在小鼠髓系细胞和人类白细胞中抑制 LAL 活性的药理作用。

期刊介绍: For over fifty years, Methods in Cell Biology has helped researchers answer the question "What method should I use to study this cell biology problem?" Edited by leaders in the field, each thematic volume provides proven, state-of-art techniques, along with relevant historical background and theory, to aid researchers in efficient design and effective implementation of experimental methodologies. Over its many years of publication, Methods in Cell Biology has built up a deep library of biological methods to study model developmental organisms, organelles and cell systems, as well as comprehensive coverage of microscopy and other analytical approaches.
