In the Sept. 15 online Early Edition of the Proceedings of the National Academy of Sciences (PNAS), researchers at the University of California, San Diego School of Medicine report that sialic acids at the tips of these cancer cell glycans are capable of engaging with immune system cells and changing the latter’s response to the tumor – for good and bad. … Read the full story from the UC San Diego Newsroom
