Flow cytometric immunophenotype (FCI) comprised P1 cells with large forward scatter, expressing CD2/CD7, CD38, CD56, CD159a, CD161
, and human leukocyte antigen-D related but negative for CD34, TDT, CD45, surface CD3, CDd5 CD138, CD19, and CD20, which indicated extranodal NKTCL.
In contrast, the effect of betamethasone dipropionate on the epidermis was restricted to a normalization of differentiation with a highly significant increase of keratin-10 positive epidermal surface without a significant effect on Ki- 67 positive nuclei, and the effect on T- cell subsets was restricted to a reduction of natural killer T-cell receptors designated by CD94 and CD161
in the epidermis.

Increase of CD69, CD161
and CD94 on NK cells in women with recurrent spontaneous abortion and in vitro fertilization failure.
Flow cytometry (FCM) analysis of the BM aspirate cells using the EuroFlow lymphoid screening tube (LST) and antibody panel for NK cell chronic lymphoproliferative diseases (NK-CLPD) , complemented with other cell surface markers, showed that the neoplastic cells were positive for CD45 (high), CD2, CD26, CD38, CD94 (high), and HLADR (high, heterogeneous) antigens, and negative for surface CD3, TCR, CD4, CD5, CD7, CD8, CD11b, CD11c, CD16, CD56, CD57, and CD161
, as well as for cytoplasmic CD3; in addition, they express intracellular granzyme B and perforin (Figure 3).
We used CD161
as a surrogate marker for Th17 cells (on [CD3.sup.+][CD4.sup.+] T cells) and we observed a decreased number of circulating Th17 cells in the patients with primary MCD in comparison to healthy controls.
Low expression of CD161
and NKG2D activating NK receptor is associated with Impaired NK cell cytotoxicity in metastatic melanoma patients.
Compared to MPB, only CD158a expression was significantly lower in APB and there wasn't a difference in the expression of CD161
and anti-Hu-KIR (p=0.0046).
In addition, IL-10KO DCs expressed greater levels of critical co-stimulatory and signaling molecules including B7.1, CCL27, CD161
and Calmodulin-dependent protein kinase when compared to WT DC.
