High levels of immunosuppressive IL1-RA in AqH of uveitis/endophthalmitis patients have also been shown in B27+ AAU patients (Zhao et al., 2015; de Vos et al., 1994; Planck et al., 2012) and may reflect the immune-privileged microenvironment in the anterior chamber (Zhao et al., 2015; de Vos et al., 1994; Planck et al., 2012; Dana et al., 1998). Here, MRAP is linked to endophthalmitis.
