The induction of colitis was associated with an increased expression of a cluster α-defensins together with the expression of other antimicrobial peptides, such as angiogenin 4 (ang4), regenerating islet derived antimicrobial peptides RegIIIγ and RegIV (reg3g and reg4, respectively), and secretory phospholipase A2 type IIA (pla2a2a/pla2g2a). Here, ANGPT4 is linked to colitis.
