Scientists at the Georg-August-University generated different monoclonal antibodies which specifically react with either Il-8RA (CXCR1, Cdw128A) or Il-8RB (CXCR2, Cdw128B), a G protein linked seven transmembrane domain protein, expressed on monocytes, granulocytes and on a subset of T cells. Interleukin-8 (IL-8) is a potent inflammatory mediator that belongs to the family of C-X-C chemokines. IL-8 promotes the activation and the extravasation of circulating neutrophils to the site of inflammation. Two IL-8 receptor isotypes (type A and B) are identified in human and rabbit neutrophils. Both receptor subtypes A and B bind with high affinity to human IL-8, but they exhibit distinct binding affinity to two functional and structurally related IL-8 peptides, melanoma growth-stimulating activity peptide (MGSA) and neutrophil-activating peptide-2 (NAP-2). Human IL-8 receptor A binds with low affinity to MGSA or NAP-2. In contrast, human IL-8 receptor B binds MGSA with high affinity, and NAP-2 with lesser affinity.
Scientists at the Georg-August-University produced different monoclonal antibodies directed against beta-arrestin1 and beta-arrestin2 (one reacts specifically with beta-arrestin1 but not beta-arrestin2, the other one with both of them). Arrestins are cytosolic proteins that are involved in G protein-coupled receptor (GPCR) desensitization. Arrestin binding to activated GPCRs phosphorylation dependent and once bound, uncouple the GPCR from the associated heterotrimeric G proteins. There are currently known 4 mammalian isoforms, beta-arrestin1 (arrestin2), beta-arrestin2 (Arrestin3), visual arrestin (Arrestin1), and cone arrestin. The beta-isoforms are ubiquitously expressed and known to interact with acetylcholine and adrenergic receptors.
