Overview
Isolate highly purified naïve CD4+ T cells from single-cell suspensions of splenocytes or other tissues by using a simple, two-step method. First, naive CD4+ T cells are pre-enriched by negative selection using the EasySep™ Mouse Naïve CD4+ T Cell Pre-Enrichment Cocktail containing biotinylated antibodies directed against non-naïve CD4+ T cells (CD8, CD11b, CD11c, CD19, CD24, CD25, CD45R, CD49b, TCRγ/δ, TER119). Then CD4+CD62L+ cells, pre-labeled with CD62L PE, are selected using the EasySep™ PE Selection Cocktail. The desired cells are labeled with antibodies and magnetic particles. The cells are separated without columns using an EasySep™ magnet.
For the isolation of mouse naïve CD4+ T cells in as little as 15 minutes by negative selection, we recommend using the EasySep™ Mouse Naïve CD4+ T Cell Isolation Kit (19765).

Figure 1. Typical EasySep™ Mouse CD4+CD62L+ T Cell Isolation Profile
Starting with a single-cell suspension of splenocytes, the naïve CD4 + T cell (CD4+CD44low CD62Lhigh) content of the final isolated fraction typically ranges from 91.7% - 96.7%. In the example above, the final purities of the start and isolated fractions are 17.9% and 92.4%, respectively.

NF-kappaB-driven miR-34a impairs Treg/Th17 balance via targeting Foxp3.
Abstract
Abstract
The subset of regulatory T (Treg) cells, with its specific transcription Foxp3, is a unique cell type for the maintenance of immune homeostasis by controlling effector T (Teff) cell responses. Although it is common that a defect in Treg cells with Treg/Teff disorder causes autoimmune diseases; however, the precise mechanisms are not thoroughly revealed. Here, we report that miR-34a could attenuate human and murine Foxp3 gene expression via targeting their 3' untranslated regions (3' UTR). The human miR-34a, increased in peripheral blood mononuclear cells (PBMCs) and CD4+ T cells from rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) patients, displayed a positive correlation with some serum markers of inflammation including rheumatoid factor (RF), anti-streptolysin antibody (ASO), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) as well as Th17 signature gene RORgammat, but inversely correlated with the mRNA expression levels of FOXP3. In addition, murine miR-34a levels were downregulated in TGF-beta-induced Treg cells but upregulated in Th17 cells induced in vitro compared to activated CD4+ T cells. It has also been demonstrated that elevated miR-34a disrupting Treg/Th17 balance in vivo contributed to the progress of pathogenesis of collagen induced arthritis (CIA) mice. Furthermore, IL-6 and TNF-alpha were responsible for the upregulation of miR-34a and downregulation of Foxp3, which was reverted by the addition of NF-kappaB/p65 inhibitor BAY11-7082, thus indicating that NF-kappaB/p65 inhibited Foxp3 expression in an miR-34a-dependent manner. Finally, IL-6 or TNF-alpha-activated p65 could bind to the miR-34a promotor and enhance its activity, resulting in upregulation of its transcription. Taken together, we show that NF-kappaB activated by inflammatory cytokines, such as IL-6 and TNF-alpha, ameliorates Foxp3 levels via regulating miR-34a expression, which provides a new mechanistic and therapeutic insight into the ongoing of autoimmune diseases.
