In a mouse endometriosis model study, researchers found that the F8 antibody had a strong targeting effect on endometriotic tissues, based on which the study significantly reduced the size of endometriosis lesions using the F8 antibody-IL-10 fusion protein55, and a similar study found that the F8 antibody-IL4 can similarly reduce the size of endometriosis lesions56. Here, IL4 is linked to endometriosis.
