- Description
- Description: The eBioRDR5 monoclonal antibody reacts with human CD127 (Interleukin-7 Receptor alpha). CD127 complexes with CD132, also known as the common gamma chain (gamma c), to form the multi-functional IL-7 receptor (IL-7R). CD127 is a type I glycoprotein with a molecular weight of 75-80 kDa and is expressed by immature B cells through the early pre-B stage, by thymocytes during several stages of their development, and on most mature T cells, with transient down-regulation upon activation. Binding of IL-7 results in signal transduction which occurs through several tyrosine kinase pathways including the Jak/STAT pathway. IL-7 is indispensible for the development of lymphocytes, and the control of homeostatic proliferation of T-cells in the periphery. In addition, IL-7R signaling is know to be involved in the regulation of T cell receptor (TCR) locus rearrangement in gamma delta T cells. Interestingly, recently it has been demonstrated that CD127 expression is down-regulated on CD4+CD25+ regulatory T cells (T regs). While the co-expression of CD4 and CD25 has become widely used as an indicator of T regs, this method of identification may also include cells without suppressive activity. It has clearly been shown that CD4+CD25+ cells that have down-regulated the expression of CD127 are significantly more highly-enriched for the regulatory T population, as defined by expression of the T reg-specific transcription factor Foxp3 and the suppressive activity of these cells, in vitro. Binding of the eBioRDR5 monoclonal antibody to PBMCs is blocked by pre-incubation of the cells with recombinant human IL-7 (cat. 14-8079). Applications Reported: This eBioRDR5 antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioRDR5 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 µL (0.125 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488 nm; Emission: 695 nm; Laser: Blue Laser. Filtration: 0.2 µm post-manufacturing filtered.

- Figure 6 In vivo knockdown of PITPNM3 in CD4 + T cells reverses immunosuppression and inhibits tumor progression in humanized mice. (A) Humanized mice bearing palpable MDA-MB-231 orthotopic xenografts were intraperitoneally injected daily for 14 days with PBS, 1 nmol CD4-aptamer-control siRNA (AsiC-con) or CD4-aptamer-siRNA targeting PITPNM3 (sequence in A , AsiC-PI) to assess the role of PITPNM3 in TI Tregs, and other T cells and tumor control. Experimental schematic is provided in Supplementary information, Figure S9A . (B) Representative immunoblots showing selective knockdown of PITPNM3 protein in PB CD4 + T cells, but not tumor xenografts ( n = 3). (C) PITPNM3 knockdown did not affect the distribution of human CD45 + hematopoietic cells, CD4 + and CD8 + T cells, and CD14 + monocytes in the peripheral blood of humanized mice. Representative flow plots are shown ( n = 3). (D , E) Effect of PITPNM3 knockdown on TI naive CD4 + , Tregs and CD8 + T cell numbers, and apoptosis by TUNEL assay in xenografts.

- Figure 4. miR-21 Promotes Effector Cell Differentiation through AP-1 Activation (A) Naive CD4 + T cells were transfected with either scrambled control or miR-21-blocking locked nucleic acid (LNA21). After 48 hr, PDCD4 and b-actin expression were assessed by western blot. Representative blots and mean normalized intensities from four experiments are shown (mean +- SEM, two-tailed paired t test). (B) Naive CD4 + T cells were activated with anti-CD3 and anti-CD28 beads and transduced with a lentiviral vector expressing scrambled control or anti-miR-21. The representative histogram shows phosphorylated JNK in GFP + cells on day 3. The filled gray histogram represents unstimulated naive CD4 + T cells. Results from 7 experiments are expressed relative to the geometric mean fluorescence intensity (MFI) of controls (mean +- SEM, two-tailed paired t test). (C) Naive CD4 + T cells were activated and transduced as described in (B) and co-transfected with the AP-1 luciferase reporter plasmid and the Renilla luciferase control construct. On day 3, the activity of AP-1 firefly luciferase was measured and normalized to that of Renilla luciferase (n = 4, mean +- SEM, two-tailed paired t test). (D-F) Naive CD4 + T cells isolated from 20- to 35-year-old and 65- to 85-year-old individuals were activated with beads coated with anti-CD3 and anti-CD28 antibodies. (D) PDCD4 expression was quantified by RT-PCR on day 3 and day 5. Results are normalized to ACTB and presented relative to
