Sex hormones regulate gut function and mucosal immunity; however, their specific effects on the mucosa-associated lymphoid tissue (MALT) in the rectum of mammals remain unclear. Here, we aimed to investigate the influence of sex on MALT in the rectum of mammals by focusing on the rectal mucosa-associated lymphoid tissues (RMALTs) of C57BL/6NCrSIc mice.
