One report addressed AnxA1 and FPRs in the case of ocular allergy. Upon the induction of allergic conjunctivitis in mice, FPR1 and FPR2 expression was increased. Interestingly, AnxA1 knockout mice showed a significant increase in FPR2 expression. AnxA1 is an anti-inflammatory mediator that decreases granulocyte infiltration and proinflammatory cytokine production in allergic conjunctivitis. These protective effects were diminished by treatment with Boc2, a pan-FPR antagonist103.
