Hypothesis-generating in cellular obesity models; leaves open clinical relevance or therapeutic targeting in patients.
Macrophage-secreted factors alter the function of human differentiated omental adipocytes, promoting a pro-inflammatory state that may contribute to obesity-associated systemic inflammation.
Bassols et al. (2009) studied Systemic chronic low-grade inflammation associated with human obesity. LPS and macrophage-conditioned media vs. Unconditioned media / no LPS was evaluated on Secretion levels of pro-inflammatory adipokines and adipocyte function. Macrophage-conditioned medium upregulated pro-inflammatory adipokines and reduced adipocyte function in human differentiated omental adipocytes, suggesting a role in obesity-associated inflammation.
