        Expression of CB2 receptor in rat dermis
        Immunohistochemical staining of paraffin embedded section of rat dermis using Anti-Cannabinoid Receptor 2 Antibody (#ACR-002), (1:100). CB2 is expressed in sebaceous glands and ducts of sweat glands in the reticular dermis. Hematoxilin is used as the counterstain.

      • Cannabinoids have been used as pain relievers in Eastern medicine for many years.1 To date, two specific cannabinoid receptors have been identified: cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2).2 The cannabinoid receptors can be distinguished by their amino acid sequence, signaling mechanisms and tissue distribution.2 Both receptors belong to the G-protein coupled receptor superfamily and are coupled to Gi/0 G protein.2,3

        The CB2 receptor is highly expressed in cells of the immune system such as macrophages, lymphocytes natural killer cells and mast cells but has also been shown to be expressed, by both, in situ-hybridization and in immunohistochemistry, in spleen, thymus, and pancreas.1,2,4 CB2 expression in the brain is still much less characterized than that of CB1. Recently, it was demonstrated that CB2 is expressed in the brain and might have a role in controlling fundamental processes such as proliferation and survival of neural cells.5,6

        Overexpression of CB2 was reported in several cancers such as prostate, glioma and acute myeloid leukemias.7-9 In human astrocytoma a direct relationship between CB2 expression and tumor malignancy was demonstrated.8 Activation of CB2 in vivo by its agonist JWH-133, completely blocked cell growth.8 In C6 glioma, it was shown that activation of the CB2 by JWH-133 resulted in the internalization of only the CB2 and not CB1 leading to apoptosis of the cells. This may well be a new approach for the treatment of glioma.

    Alomone is pleased to offer a new antibody directed against an intracellular epitope of the rat CB2 receptor. Anti-Cannabinoid Receptor 2 Antibody (#ACR-002) can be used in western blot and immunohistochemistry applications, and recognizes CB2 in rat samples.
