CNR2 and uveitis: More recently, Porter et al. demonstrated that the topical application of synthetic cannabinoid agonists of CB2 RO6871304 and RO6871085, as well as HU910 (1.5% w/v in Tocrisolve®), was effective to attenuate the adhesion of leukocytes to the iris microvasculature, especially for RO6871304, in uveitis induced by endotoxins [89].
