NK cells comprise two main . Different subtypes of human NK cells have been identified that are either CD3-CD56 dim . CD56 bright CD16 − NK cells preferentially localize to secondary lymphoid tissues and CD56 dim CD16 + cells occupy peripheral blood, lungs, and sites of inflammation ( 45 , 51 – 54 ).In human peripheral blood, NK cells are defined as CD56 + CD3 − cells, which can be further characterized based on the relative expression of the CD16 and CD56 markers. NKG7 Is a T-cell-Intrinsic Therapeutic Target for Improving Antitumor Cytotoxicity and Cancer Immunotherapy Cancer Immunol Res. In peripheral blood, NK cells are commonly classified into two major subsets: CD56 bright CD16 neg and CD56 dim CD16 pos despite the characterization of a CD56 neg CD16 pos subset 25 years ago.
Moreover, numerical and functional deficiencies and phenotypic alterations of CD56+ immune cells have been reported in patients with various infectious, autoimmune or malignant diseases.

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. 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 . In addition, a . 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 . 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. References: Van Acker HH, Capsomidis A, Smits EL, Van Tendeloo VF.
Distinctive CD56 dim NK subset profiles and increased NKG2D
As CD56 + CD8 + peripheral T cells are considered the most cytotoxic [5, 7], we evaluated the content of CD56 + cells in the CD8 + subset.Differences in marker expression between CD56 bright NK cells and CD56 dim NK cells.The share of NK cells in cytotoxicity responses can be monitored by a multicolor flow cytometry panel with a selection of antibodies including the pan NK marker CD56.
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.
Shining light on the significance of NK cell CD56 brightness
In addition, it has been suggested that CD56 expression in DLBCL could be related to a more frequent extranodal presentation associated to the adhesive properties of CD56.StraightFrom CD56 MicroBeads, human) and untouched isolation (left column, NK cell isolation kit, human). 27 It may be involved in homophilic adhesion for NK and T cells . Over the past years, the phenotypic and functional boundaries distinguishing the main cell subsets . Backgating on B-cell and plasma cell lineage markers was used to ensure that CD56 + plasma cells were not included within the NK gate. In addition, a positive correlation was found between surface CD56 expression and cytotoxic activity or IFN-γ mRNA gene expression.Pseudotime analysis identified a subset of resident CD56 bright NK cells, NK0 cells, as the precursor of both circulating CD56 dim NK1-like NK cells and CD56 .

Natural Killer Cell Markers
CD56 bright CD16 − cells exhibit superior cytokine production, whereas CD56 dim CD16 + cells primarily demonstrate enhanced cytotoxicity (20, 44–47). Here, the expression of CD56 is most stringently associated with, but certainly not limited to, natural killer (NK) cells (Figure 1) ( 3).Europe PMC is an archive of life sciences journal literature.CD56 is a well-known marker for human NK cells, but there is very limited information about a functional role of this surface receptor. Cell numbers increased 1. f , UMAP embeddings of CD4 + T clusters.Together, these data confirm that CD56 neg CD16 pos cells are legitimate NK cells, yet their transcriptional and protein expression profiles suggest their cytotoxic . Expression of these markers was decreased at 5% and 2.To investigate CIK cells’ nature, we examined their CD markers’ expression, including CD3+, CD56+, and CD3 + CD56 + markers using flow cytometry. While one study showed that CD56 can inhibit NK cell killing, another study concluded no effect of CD56 on the cytotoxicity of NK cells [26, 45].
