Control Gene For "Conveyor Belt" Cells Could Help Improve Oral Vaccines, Treat Intestinal Disease, Emory University School of Medicine Study

Scientists have found a master regulator gene needed for the development of M cells, a mysterious type of intestinal cell involved in initiating immune responses. M cells act like "conveyor belts," ingesting bacteria and transporting substances from the gut into Peyer's patches, specialized tissues resembling lymph nodes in the intestines. Better knowledge of M cells' properties could aid research on oral vaccines and inflammatory bowel diseases.
