AI Summary (NQ-processed)
A research group led by Professor Eisuke Itakura at Chiba University's Graduate School of Science has discovered that the blood protein GPLD1 acts as a scavenger carrier, directly capturing the abnormal protein serum amyloid A1 (SAA1), the cause of the intractable disease AA amyloidosis, and transporting it to lysosomes within cells for degradation.
