Myeloid-derived suppressor cells (MDSCs) are potent suppressors of T cell immunity in tumors and inflammatory diseases. They are identified by surface expression of CD11b+Gr1+ in mice, and CD11b+Gr1+ cells accumulate in the livers of obese mice. However, many myeloid cells

Serum protein glycation and formation of advanced glycation endproducts (AGE) correlates with diabetic complications. Highly AGE-modified albumin is frequently used to study the biochemical and cellular activities of AGE-proteins. However, moderately modified albumin samples are expected to be (patho)physiologically more

A sensitive and reliable LC-(ESI)MS/MS method was developed and validated for the simultaneous analysis of five common advanced glycation endproducts (AGEs) after enzymatic digestion in raw and roasted almonds. AGEs included carboxymethyl-lysine (CML), carboxyethyl-lysine (CEL), pyralline (Pyr), argpyrimidine (Arg-p), and
