To examine the role of myeloid-derived CCL5 in obesity-associated metabolic abnormalities, we used BM-specific BMT chimeras in which WT mice were irradiated and given the BM of WT or CCL5KO mice to generate L5KO/WT and WT/WT mice and examine whether the loss of CCL5 from hematopoietic cells could influence adipose tissue inflammation. Here, CCL5 is linked to Obesity.
