PTX3 and chronic kidney disease: As suggested by previous observational data from our group, showing associations between fat mass and plasma levels of PTX3 in CKD patients [40], as well as the emerging literature on plausible pathophysiological interactions between fat and inflammatory modulators in CKD [35], [36], [37], [38], [39], adipose tissue may represent a promising target for studies on local PTX3 expression.
