Interleukin 15 (IL-15) is a novel cytokine that has recently been cloned and expressed. Whereas it has no sequence homology with IL-2, IL-15 interacts with components of the IL-2 receptor (IL-2R). In the present study we performed a functional analysis of recombinant IL-15 on phenotypically and functionally distinct populations of highly purified human(More)
Human natural killer (NK) cells are large granular lymphocytes that constitutively express functional forms of the interleukin-2 receptor (IL-2R) and lyse tumor and virally infected cells without prior sensitization. NK cells with high density expression of CD56 (CD56bright) express the high affinity IL-2R and proliferate in response to low (picomolar)(More)
The origin, lineage derivation, and sites of human natural killer (NK) cell differentiation are presently unresolved. The vast majority of NK cells found in peripheral blood have surface membrane expression of CD2 and CD16. Both antigens trigger activation pathways which require the zeta protein, a signal-transducing subunit of the CD3-T cell receptor(More)
