Overview

Isolate highly purified human CD33+ myeloid cells from fresh human whole blood or buffy coat samples by immunomagnetic positive selection, with the EasySep™ HLA Chimerism Whole Blood CD33 Positive Selection Kit. Widely used in published research for more than 20 years, EasySep™ combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system.

In this EasySep™ positive selection procedure, desired cells are labeled with antibody complexes recognizing CD33 and magnetic particles. Labeled cells are separated using an EasySep™ magnet and by simply pouring or pipetting off the unwanted cells. The cells of interest remain in the tube. Following magnetic cell isolation, the desired CD33+ cells are ready for downstream applications such as flow cytometry, culture, or DNA/RNA extraction for lineage-specific chimerism analysis. The CD33 antigen is expressed on myeloid progenitor cells, granulocytes, and monocytes.

This product replaces the EasySep™ Human Whole Blood CD33 Positive Selection Kit (Catalog #18287) and EasySep™ HLA Whole Blood CD33 Positive Selection Kit (Catalog #18287HLA) for even faster cell isolations.

Data Figures

Typical EasySep™ HLA Chimerism Whole Blood CD33 Positive Selection Profile

Figure 1. Typical EasySep™ HLA Chimerism Whole Blood CD33 Positive Selection Profile

Starting with fresh whole blood, the CD33+ cell content of the isolated fraction is typically 96 ± 2% (mean ± SD) using “The Big Easy” EasySep™ Magnet. In the above example, the purities of the start (as assessed by labeling with anti-CD33) and the final isolated fractions are 68.0% and 96.2% (as assessed by labeling with anti-CD14 and anti-CD66b), respectively.
NOTE: RBCs were removed from the start sample by lysis prior to flow cytometry.

Antibody-Mediated LILRB2-Receptor Antagonism Induces Human Myeloid-Derived Suppressor Cells to Kill Mycobacterium tuberculosis. V. K. Singh et al. Frontiers in immunology 2022

Abstract

Tuberculosis is a leading cause of death in mankind due to infectious agents, and Mycobacterium tuberculosis (Mtb) infects and survives in macrophages (MФs). Although MФs are a major niche, myeloid-derived suppressor cells (MDSCs) are an alternative site for pathogen persistence. Both MФs and MDSCs express varying levels of leukocyte immunoglobulin-like receptor B (LILRB), which regulate the myeloid cell suppressive function. Herein, we demonstrate that antagonism of LILRB2 by a monoclonal antibody (mab) induced a switch of human MDSCs towards an M1-macrophage phenotype, increasing the killing of intracellular Mtb. Mab-mediated antagonism of LILRB2 alone and its combination with a pharmacological blockade of SHP1/2 phosphatase increased proinflammatory cytokine responses and phosphorylation of ERK1/2, p38 MAPK, and NF-kB in Mtb-infected MDSCs. LILRB2 antagonism also upregulated anti-mycobacterial iNOS gene expression and an increase in both nitric oxide and reactive oxygen species synthesis. Because genes associated with the anti-mycobacterial function of M1-MФs were enhanced in MDSCs following mab treatment, we propose that LILRB2 antagonism reprograms MDSCs from an immunosuppressive state towards a pro-inflammatory phenotype that kills Mtb. LILRB2 is therefore a novel therapeutic target for eradicating Mtb in MDSCs.
