Using microRNA Fit to a T (cell)

Researchers show B cells can deliver potentially therapeutic bits of modified RNA

Researchers at the University of California, San Diego School of Medicine have successfully targeted T lymphocytes – which play a central role in the body’s immune response – with another type of white blood cell engineered to synthesize and deliver bits of non-coding RNA or microRNA (miRNA). … Read the full story from the UC San Diego News Center

Stress Signal in Cancer Cells Triggers Similar Response in Other Cells, Aiding Tumor Growth

Researchers at the University of California, San Diego School of Medicine say a “stress response” mechanism used by normal cells to cope with harsh or demanding conditions is exploited by cancer cells, which transmit the same stress signal to surrounding cells, triggering an inflammatory response in them that can aid tumor growth….
