A protocol for isolation of primary human immune cells from the liver and mesenteric white adipose tissue biopsies

Isolation of viable immune cells from human tissues is critical for the characterization of cellular and molecular processes underlying disease pathogenesis. Here, we describe protocols for the isolation of highly viable immune cells from liver wedges and mesenteric white adipose tissue resections from obese persons. Notably, characterization of the isolated single-immune cell suspensions, via utility of basic immunological interrogations and genetic approaches, promises to generate an improved understanding of altered immunological pathways in obese individuals with or without metabolic diseases. For complete details on the use and execution of this protocol, please refer to Moreno-Fernandez et al. (2021).
