Abstract: One example method of operation may include identifying a call originated from a caller entity destined for a called entity at a call content server, identifying a called number associated with the called entity and a caller number associated with the caller entity, comparing a telephone number prefix associated with the called number with a number of enhanced call content data elements to identify a match, selecting one or more of the enhanced call content data elements to pair with the called number based on the match, and forwarding the selected enhanced call content data elements to the called entity.

Abstract: The present invention provides the nucleotide and amino acid sequence of truncated RANTES (3-68), which has the same amino acid sequence as the wild-type RANTES, but with a Serine/Proline truncation at positions 1 and 2 from the N-terminus, respectively. CD26 is a leukocyte activation marker that possesses dipeptidyl peptidase IV (DPPIV) activity but whose natural substrates and immunological functions had not been previously defined. Several chemokines, including RANTES (regulated on activation, normal T expressed and secreted) are provided, which are substrates for human CD26. The truncated RANTES (3-68) lacked the ability of native RANTES (1-68) to increase the cytosolic calcium concentration in human monocytes, but it still induces this response in macrophages activated with macrophage colony-stimulating factor (M-CSF). RANTES (3-68) retains the ability to stimulate CCR5 receptors and to inhibit the cytopathic effects of HIV-1.
