CD335 antibody | AKS1
Mouse anti bovine CD335 antibody, clone AKS1 (MCA2365GA) used for the isolation by immunomagnetic separation and evaluation of CD335 expression by flow cytometry of NKp46 expression on bovine peripheral blood mononuclear cells.
Image caption:
CD2 distribution on bovine NK cells in peripheral blood and during cell culture. (A) CD2 expression by PBMCs from healthy cattle, and in NKp46-selected cells cultured for the indicated time in the presence of 100U/ml rbIL-2. Results were obtained by two-colour flow cytometry, gating for viable lymphocytes. Data shown are from one animal representative of 19. (B) Monitoring of cell divisions of CD2- and CD2+ NK cell populations during three and six days of rbIL-2 (100U/ml) stimulation. NKp46-selected cells were labelled with CFSE the day after isolation and CFSE intensity (filled histograms) measured in flow cytometry on the indicated days, gating for CD2- or CD2+ viable cells. Solid line open histograms show non-dividing NK cells, cultured in the presence of 1U/ml rbIL-2, while broken line open histograms show unlabeled stimulated NK cells. Data shown are from one animal representative of five. (C) Stability of CD2 expression in NK cell subsets cultured separately. NK cells separated with immunomagnetic beads for absence or presence of CD2 were cultured separately for eleven days in the presence of IL-2, monitoring CD2 expression at three different time points (filled histograms). Day 1 corresponds to the day of separation, 24 h after primary NK cell isolation. Open histograms show secondary mAb controls. Data shown are from one animal representative of eight.

Image caption:
Effect of anti-CD2 mAbs on bovine NK cell functions. (A) IFN-γ response from NK cells caused by cross-linking of CD2. Plastic wells were pre-coated with two different mAbs against bovine CD2, along with NKp46-mAb as positive control and CD8-mAb or medium as negative controls. rbIL-2 activated NK cells were added and incubated for 24 h in the presence or absence of rbIL-12 (0.5 U/ml), and IFN-γ content in the supernatants analyzed by an ELISA. Data shown are means ± SD of two to four individual animals. (B-C) IL-2 activated NK cell killing of the bovine target lines BL3.1 and MDBK in a 4 h 51Cr-release assay, with addition of the indicated mAbs for blocking. CD2mAb I = BAQ95A, CD2 mAb II = MUC2A, CD8 mAb = CACT80C, NKp46 mAb = AKS1. (D) As above, using murine Fc-receptor bearing P815 target cells to obtain a redirected lysis effect. Data shown in (B-D) are from one animal representative of three to five.

Oenothein B Primes bovine CD335+ cells to respond to IL-18. (A) Bovine PBMCs (105 cells/well) were depleted of CD335+ cells and treated with 20 μg/ml oenothein B or X-VIVO medium alone for 24 hrs. Cells were then washed and treated with 10 ng/ml rhu IL-18 or medium alone for 18 hrs. After incubation, IFNγ levels in the supernatant fluids were measured by ELISA. The data are expressed as mean +/− SEM of three independent experiments comparing depleted PBMCs to un-depleted controls tested concurrently. All samples were tested in duplicate or triplicate. Statistical significance was measured by Two-way ANOVA with Bonferroni post-test. *p<0.05, **p<0.01, ***p<0.001 (B) Bovine PBMCs (105 cells/well) from a new calf were treated with the indicated amounts of oenothein B or X-VIVO medium alone for 24 hrs. Cells were washed and treated with 10 ng/ml rhu IL-18 or X-VIVO medium alone for 6 hrs in the presence of brefeldin A. IFNγ production was measured by intracellular flow cytometry. The data are expressed as mean+/− SEM. All samples were tested in triplicate. Statistical significance was measured by Two-way ANOVA with Bonferroni post-test. *p<0.05, **p<0.01, ***p<0.001 (C) Representative examples of two-color flow cytometry plots comparing IFNγ staining on CD335+ cells.

Unrivaled 
| Mouse anti Bovine CD335 antibody, clone AKS1 recognizes bovine CD335, also known as NKp46 and Natural cytotoxicity triggering receptor 1. CD335 is a type I transmembrane protein, with two extracellular C2-type immunoglobulin-like domains, which functions as an activating receptor. CD335 is expressed by human natural killer cells (Sivori et al. 1997). The bovine homologue is expressed on bovine NK cells (Storset et al. 2004) and no expression of CD335 has been detected on B cells, T cells, monocytes or granulocytes. Clone AKS1 is reported to activate lysis of FcgammaR-expressing cell line P815, by IL-2 activated NKp46+ cells (Storset et al. 2004). |
