Karolinska Institutet researchers have demonstrated that B lymphocytes, on which the efficient operation of the immune system depends, can occasionally cause more harm than good since their numbers sharply increase following intestinal trauma, impeding the healing process.
B cells are critical to the proper functioning of the immune system. However, researchers at Karolinska Institutet have shown that they can sometimes do more harm than good, as their numbers greatly increase after bowel damage, preventing the tissue from healing. The results, which are presented in the journal Immunity, can be of significance to the treatment of inflammatory bowel disease.
