CD56 in the Immune System: More Than a Marker for Cytotoxicity?
CD56 is often considered a marker of neural lineage commitment due to its discovery site ( 2). However, in the 5% hPL group, more than 40% of the cells express CIK CD markers .3 to 3 fold, (from Day 4-7 after sorting, to allow cells to recover), dependent on the donor. Increased expression of CD107a after IL-2 stimulation of NK cells was parallel to the increase of cytotoxicity. 2022 Feb;10(2):162-181. published: 24 July 2017 doi: 10. However, CD56 expression is also found in, among others, the hematopoietic system. An increase in the . O Penack1, C Gentilini1, L Fischer1, AM Asemissen1, C Scheibenbogen1, E Thiel1 and L . Expression of CD16 was determined in CD3–CD56+ NK cells as well as CD25 and CD69 were measured as indication of cell activation. In addition to monitoring infection and immune status, CD antigens can be used to detect the abnormal growth of .However, the T-cell intrinsic factors required for human CTLs to accomplish highly efficient antitumor cytotoxicity are not well defined. We revealed that the quantification of surface CD56 .It was observed that NCAM/CD56 had no impact on the lysis effect of target cells 46, 47 whereas on the other hand, other reports demonstrated that the cytotoxicity of NK cells interacting with . These reports suggested a functional role of NCAM/CD56 in the recognition of target .CD56 is the archetypal phenotypic marker of natural killer cells but can actually be expressed by many more immune cells, including alpha beta T cells, gamma .
Since then, several studies have described . Under homeostatic conditions, CD56 bright NK cells and CD56 dim NK cells express a variety of activation, functional and migratory markers that can be used to differentiate them, but also to explain their different locations and functions. Our results suggest that CD107a expression may be a sensitive marker for the cytotoxic activity determination.It was observed that NCAM/CD56 had no impact on the lysis effect of target cells 46, 47 whereas on the other hand, other reports demonstrated that the cytotoxicity of NK cells interacting with NCAM-expressing target cells is enhanced by NCAM/CD56 48, 49. Despite their low reliance on CD56 for cytotoxicity (2), CD56 is found at the YTS cell immune synapse (Fig.
Distinctive CD56 dim NK subset profiles and increased NKG2D
Monitoring CD56 and CD3 markers in NK and LAK cultures from 4 healthy donors up to 25 days showed that NK cultures remained pure over time, starting from 94%-98% to 91%-96% NK cells in culture after expansion.CD56 expression on CD3 + T cells has been associated with enhanced cytotoxicity and pro-inflammatory function [ 1 ].However, on the basis of the differential expression of the surface markers CD11b and CD27, .
CD56 Antigen
This observation implies that CD56 is a potential predictive biomarker of breast cancer sensitivity to NK-92-mediated cytotoxicity, which seems to be tissue specific as the highly sensitive K562 leukemia cells didn’t express this marker.IL-2 stimulation resulted in a significant increase of CD107a expression in CD56+ NK, CD8+ T cells and lymphocytes.The CD56 dim subset was defined as CD16 + CD56 low, and the CD56 bright subset was CD16 +/− CD56 high.
