A Masked Intruder: Extranodal Natural Killer/T-Cell Lymphoma Mimicking Preseptal Cellulitis

In this paper, we describe a method to measure glycolysis and mitochondrial respiration in primary human Natural Killer (NK) cells isolated from peripheral blood, at rest or following IL15-induced activation. The protocol described could be easily extended to primary human NK cells activated by other cytokines or soluble...

Here, we present a protocol to mass-produce gene-silencing murine NK cells by using a feeder-free differentiation system for mechanistic study in vitro and in...

This video demonstrates a technique for the expansion of natural killer (NK) cells directly from peripheral blood mononuclear cells (PBMCs) using a feeder cell line. PBMCs are co-cultured with genetically modified lymphoblastoid feeder cells expressing membrane-bound interleukin-21 (mIL-21), and the culture is supplemented with the cytokines interleukin-2 (IL-2) and interleukin-15 (IL-15). Together, this cocktail of ligands leads to the prolonged expansion of NK cells with high...

This video demonstrates the isolation of lymphocytes, including natural killer cells or NK cells, from human liver tissue for selective expansion. Enzymatic and mechanical digestion, followed by density gradient separation, promotes lymphocyte isolation, including NK cells. The collected lymphocytes can be further used for the selective expansion of NK...

This video describes the isolation of DRG neurons through enzymatic digestion, mechanical dissociation, and gradient centrifugation. The DRG cells are co-cultured with natural killer cells on an extracellular matrix to study the interaction between immune cells and sensory...

This video illustrates a method for isolating invariant natural killer T cells, also known as iNKT cells. The procedure begins with injecting a synthetic glycolipid into a mouse to stimulate the activation and proliferation of iNKT cells in the spleen. Subsequently, single-cell suspensions are prepared from the spleen and incubated with iNKT-cell-recognizing complexes labeled with fluorophores, followed by magnetic bead-based separation, to isolate the iNKT...
