- Description
- Description: This TXRX10 monoclonal antibody reacts with human and mouse TOX, which is also known as Thymocyte selection-associated HMG box protein. This DNA-binding nuclear factor is expressed in thymocytes, T lymphocytes, NK cells, and lymphoid tissue-inducer (LTi) cells. TOX expression in thymocytes is upregulated during beta-selection and positive selection. Studies using Tox knockout mice have demonstrated a critical role for TOX in CD4+ T cell development as a regulator of the CD4loCD8lo to CD4+CD8lo transition. Moreover, TOX has been shown to be involved in the development of NK and LTi cells. While its regulation remains unclear, TOX expression has been shown to be induced by calcineurin-mediated TCR signaling in thymocytes during positive selection.

- C57Bl/6 thymocytes were stained with Anti-Mouse CD4 APC (Product # 17-0041-82) and Anti-Mouse CD8a FITC (Product # 11-0081-82), followed by intracellular staining with 0.5 µg of Anti-Human/Mouse TOX PE using the Foxp3 Staining Buffer Set and protocol (Product # 00-5521-00). The histogram (right) demonstrates TOX staining of CD4+CD8+ (blue histogram), CD4loCD8lo (green histogram), and CD4+CD8lo (purple) thymocytes. Cell populations were gated as indicated on the dot plot (left). Cells in the lymphocyte gate were used for analysis.

- Figure 6 Vav1 DeltaC -mediated proliferation requires engagement of several downstream pathways A Schematic representation of the experiments used in this figure. See details in main text and Materials and Methods. B Depiction of the Vav1 mutants used in these experiments. The E201A mutation is shown as a gray circle. The activity of each mutant is represented on the right. Green box, WT activity; red box, gain of function; blue box, loss of function. C Representative immunoblot showing the abundance of the ectopic Vav1 proteins, EGFP, and the endogenous tubulin alpha (loading control) in CD4 + T cells transduced with retrovirus particles used in these experiments (top). D Representative FACS plots showing EGFP epifluorescence in CD4 + T cells transduced with retroviruses encoding the indicated proteins (top). Numbers indicate the relative percentage (%) of the EGFP + cell population in each case. Gray shaded histograms represent the fluorescence obtained from CD4 + T cells nontransduced with retrovirus particles. Similar results were obtained in CD4 + T cells transduced with virus encoding EGFP ( n = 6), Vav1 WT ( n = 6), Vav1 DeltaC ( n = 6), Vav1 DeltaC+E201A ( n = 6), and Vav1 DeltaN ( n = 3).

In A, gray shaded histograms represent the fluorescence obtained from nonstimulated CD4 + T cells before stimulation and retroviral transduction. n = 3 independent experiments. C-E Flow cytometry determination of intracellular Tox (C), intracellular ICN1 (D), and surface ICOS (E) levels in EGFP + CD4 + T cells expressing the indicated Vav1 proteins. f.i., mean fluorescence intensity relative to the isotype-matched control antibody. n = 3 independent experiments.

The other downstream effectors and pathways of Vav1 are indicated. The main primary effectors as shown in red. Data information: In panels (B, C, D, and E), values are shown as means +- SEM from three independent experiments. P -values are given relative to nontreated (light blue asterisks) and treated (dark blue asterisks) EGFP + cells. We also include P -values for the values exhibited by each experimental group relative to those obtained in nontreated condition (black asterisks). * P
