Overview

The EasySep™ Mouse Naïve CD4+ T Cell Isolation Kit is designed to isolate naïve CD4+ T cells from single-cell suspensions of splenocytes or other tissues by negative selection. Unwanted cells are targeted for removal with biotinylated antibodies directed against non-naïve CD4+ T cells (CD8, CD11b, CD11c, CD19, CD24, CD25, CD44, CD45R, CD49b, TCRγ/δ, TER119) and streptavidin-coated magnetic particles (RapidSpheres™ ). Labeled cells are separated using an EasySep™ magnet without the use of columns. Desired cells are poured off into a new tube.

ImmunoCult™ Mouse Treg Differentiation Supplement Produces CD4+CD25+FOXP3+ Cells Under Treg Polarizing Conditions

Figure 3. ImmunoCult™ Mouse Treg Differentiation Supplement Produces CD4+CD25+FOXP3+ Cells Under Treg Polarizing Conditions

Naïve CD4+ T cells were isolated from mouse splenocytes using the EasySep™ Mouse Naive CD4+ T Cell Isolation Kit (Catalog #19765), activated with plate-bound anti-CD3 and soluble anti-CD28 and cultured in medium alone (Non-polarizing cultures), or in medium supplemented with ImmunoCult™ Mouse Treg Differentiation Supplement (Catalog #10957; polarizing cultures) for 6 days. Cells were subsequently stained with anti-CD4, anti-CD25, anti-FOXP3, and a viability dye and analyzed by flow cytometry. Shown is the expression of CD25 and FOXP3 back-gated on viable CD4+ cells from non-polarized (A) or polarized cultures (B). The mean proportion of CD4+FOXP3+ cells is significantly higher in cells cultured in ImmunoCult™ Mouse Treg Differentiation Supplement (91 ± 2%) compared to non-polarized cells (2 ± 0.4%) (p < 0.001; n = 14). Data from experimental groups were compared using a paired T-test.

Naïve CD4+ T cells were isolated from mouse splenocytes using the EasySep™ Mouse Naive CD4+ T Cell Isolation Kit (Catalog #19765), activated with plate-bound anti-CD3 and soluble anti-CD28, and cultured in medium alone, or medium containing ImmunoCult™ Mouse Treg Differentiation Supplement (Catalog #10957) for 6 days. A 3.6-fold expansion of total nuclear cells (TNC) occurs in cultures polarized with ImmunoCult™ Mouse Treg Differentiation Supplement (purple column), which is significantly higher compared to non-polarized cultures (grey column). (Data represent the mean ± SEM, n = 14, ***p < 0.001. Data from experimental groups were compared using a paired T-test).

Frequently Asked Questions

Can EasySep™ Streptavidin RapidSpheres™ be used for either positive or negative selection?

Currently, EasySep™ Streptavidin RapidSphere™ kits are only available for negative selection and work by targeting and removing unwanted cells.

How does the separation work?

Streptavidin RapidSphere™ magnetic particles are crosslinked to unwanted cells using biotinylated antibodies. When placed in the EasySep™ Magnet, labeled cells migrate to the wall of the tube. The unlabeled cells are then poured off into a new tube.

Which columns do I use?

The EasySep™ procedure is column-free. That's right - no columns!

How can I analyze the purity of my enriched sample?

The Product Information Sheet provided with each EasySep™ kit contains detailed staining information.

Can EasySep™ Streptavidin RapidSphere™ separations be automated?

Yes. RoboSep™, the fully automated cell separator, automates all EasySep™ labeling and cell separation steps.

Are cells isolated using EasySep™ RapidSphere™ products FACS-compatible?

Yes. Desired cells are unlabeled and ready to use in downstream applications, such as FACS analysis.

Can I alter the separation time in the magnet?

Yes; however, this may impact the kit's performance. The provided EasySep™ protocols have already been optimized to balance purity, recovery and time spent on the isolation.

Prolonged residence of an albumin-IL-4 fusion protein in secondary lymphoid organs ameliorates experimental autoimmune encephalomyelitis. A. Ishihara et al. Nature biomedical engineering 2020 oct

Abstract

Interleukin-4 (IL-4) suppresses the development of multiple sclerosis in a murine model of experimental autoimmune encephalomyelitis (EAE). Here, we show that, in mice with EAE, the accumulation and persistence in the lymph nodes and spleen of a systemically administered serum albumin (SA)-IL-4 fusion protein leads to higher efficacy in preventing disease development than the administration of wild-type IL-4 or of the clinically approved drug fingolimod. We also show that the SA-IL-4 fusion protein prevents immune-cell infiltration in the spinal cord, decreases integrin expression in antigen-specific CD4+ T cells, increases the number of granulocyte-like myeloid-derived suppressor cells (and their expression of programmed-death-ligand-1) in spinal cord-draining lymph nodes and decreases the number of T helper 17 cells, a pathogenic cell population in EAE. In mice with chronic EAE, SA-IL-4 inhibits immune-cell infiltration into the spinal cord and completely abrogates immune responses to myelin antigen in the spleen. The SA-IL-4 fusion protein may be prophylactically and therapeutically advantageous in the treatment of multiple sclerosis.
Synoviocyte-targeted therapy synergizes with TNF inhibition in arthritis reversal. M. N. D. Svensson et al. Science advances 2020 jun

Abstract

Fibroblast-like synoviocytes (FLS) are joint-lining cells that promote rheumatoid arthritis (RA) pathology. Current disease-modifying antirheumatic agents (DMARDs) operate through systemic immunosuppression. FLS-targeted approaches could potentially be combined with DMARDs to improve control of RA without increasing immunosuppression. Here, we assessed the potential of immunoglobulin-like domains 1 and 2 (Ig1{\&}2), a decoy protein that activates the receptor tyrosine phosphatase sigma (PTPRS) on FLS, for RA therapy. We report that PTPRS expression is enriched in synovial lining RA FLS and that Ig1{\&}2 reduces migration of RA but not osteoarthritis FLS. Administration of an Fc-fusion Ig1{\&}2 attenuated arthritis in mice without affecting innate or adaptive immunity. Furthermore, PTPRS was down-regulated in FLS by tumor necrosis factor (TNF) via a phosphatidylinositol 3-kinase-mediated pathway, and TNF inhibition enhanced PTPRS expression in arthritic joints. Combination of ineffective doses of TNF inhibitor and Fc-Ig1{\&}2 reversed arthritis in mice, providing an example of synergy between FLS-targeted and immunosuppressive DMARD therapies.
Mitochondrial Oxidative Phosphorylation Regulates the Fate Decision between Pathogenic Th17 and Regulatory T Cells. B. Shin et al. Cell reports 2020 feb

Abstract

Understanding metabolic pathways that regulate Th17 development is important to broaden therapeutic options for Th17-mediated autoimmunity. Here, we report a pivotal role of mitochondrial oxidative phosphorylation (OXPHOS) for lineage specification toward pathogenic Th17 differentiation. Th17 cells rapidly increase mitochondrial respiration during development, and this is necessary for metabolic reprogramming following T cell activation. Surprisingly, specific inhibition of mitochondrial ATP synthase ablates Th17 pathogenicity in a mouse model of autoimmunity by preventing Th17 pathogenic signature gene expression. Notably, cells activated under OXPHOS-inhibited Th17 conditions preferentially express Foxp3, rather than Th17 genes, and become suppressive Treg cells. Mechanistically, OXPHOS promotes the Th17 pioneer transcription factor, BATF, and facilitates T cell receptor (TCR) and mTOR signaling. Correspondingly, overexpression of BATF rescues Th17 development when ATP synthase activity is restricted. Together, our data reveal a regulatory role of mitochondrial OXPHOS in dictating the fate decision between Th17 and Treg cells by supporting early molecular events necessary for Th17 commitment.
