Inflammatory response in white adipose tissue in the non-obese hormone-sensitive lipase null mouse model

In the present study, a local inflammatory response in white adipose tissue from the nonobese HSL-null mouse model is demonstrated. The protein levels of several well-known markers of inflammation, like TNF alpha and ferritin HC, were highly increased and accompanied by an activation of NF kappa B. A number of macrophage proteins, i.e., gal-3, Capg, and MCP-4, were expressed at increased levels and immunohistochemical analyses revealed an increased infiltration of F4/80+ cells.
