Quantification of Adipose Tissue Leukocytosis in Obesity

The infiltration of immune cell subsets in adipose tissue termed “adipose tissue leukocytosis” is a critical event in the development of chronic inflammation and obesity-associated comorbidities. Given that a significant proportion of cells in adipose tissue of obese patients are of hematopoietic lineage, the distinct adipose depots represent an uncharacterized immunological organ that can impact metabolic functions. Here, we describe approaches to characterize and isolate leukocytes from the complex adipose tissue microenvironment, to aid mechanistic studies to better understand the role of specific pattern recognition receptors (PRRs) such as inflammasomes in adipose-immune cross talk.
