| Galton's delta | A more or less well-marked triangle, in a fingerprint, on either side where the straight ridges near the joint of the distal phalanx are succeeded by arches, loops, or whorls. See: Galton's system of classification of fingerprints. Synonym: triradius. (05 Mar 2000) |
| gene rearrangement, delta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the delta-chain of antigen receptors. (12 Dec 1998) |
| genes, T-cell receptor delta | DNA sequences encoding the delta chain of the T-cell receptor. The delta-chain locus is located entirely within the alpha-chain locus. (12 Dec 1998) |
| receptors, antigen, T-cell, gamma-delta | T-cell receptors composed of CD3-associated gamma and delta polypeptide chains and expressed primarily in CD4-/CD8- T-cells. The receptors appear to be preferentially located in epithelial sites and probably play a role in the recognition of bacterial antigens. The T-cell receptor gamma/delta chains are separate and not related to the gamma and delta chains which are subunits of CD3 (see antigens, CD3). (12 Dec 1998) |
| receptors, opioid, delta | A class of opioid receptors recognised by its pharmacological profile. Delta opioid receptors bind endorphins and enkephalins with approximately equal affinity and have less affinity for dynorphins. (12 Dec 1998) |
