Abstract:
Chemokine receptors play a major role in the mobilization and activation of the cells of the immune system, and are discussed in this review by Richard Horuk. Six receptors that bind chemokines with high affinity have been cloned and all belong to the superfamily of G protein-coupled receptors. Chemokine receptors are mainly expressed in immune cells, which are their major target cells. However, two of the cloned receptors are expressed by viruses and may play a role in protecting the virus from immune surveillance. In addition, a novel chemokine receptor that is expressed in human erythrocytes not only binds CC and CXC chemokines with high affinity but is also a receptor for the malarial parasite Plasmodium vivax.

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR activation may...
G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
