AI Article Synopsis
- Cytotoxic T cells (CTLs) and natural killer (NK) cells are crucial for fighting against tumors and viral infections within the immune system.
- A flow cytometry technique is described to measure the effectiveness of these effector lymphocytes in killing melanoma cells.
- The method involves co-incubating immune cells with labeled tumor cells, allowing researchers to identify dead target cells for diagnostic and research purposes.
Article Abstract
Within the adaptive and innate immune system, effector lymphocytes known as cytotoxic T cells (CTLs) or natural killer (NK) cells play an essential role in host defense against tumor cells and virally infected cells. Here we describe a flow cytometry-based method to quantify CTLs or NK cell cytotoxic activity against melanoma cells. In this assay, spleen cells, peripheral blood mononuclear cells (PBMCs), or purified NK cell preparations are co-incubated at different ratios with a target tumor cell line. The target cells are pre-labeled with a fluorescent dye to allow their discrimination from the effector cells. After the incubation period, killed target cells are identified by a nucleic acid stain, which specifically permeates dead cells. This method is amenable to both diagnostic and research applications.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the result of an exaggerated inflammatory response triggered by a variety of pulmonary and systemic insults. The lung tissues are comprised of a variety of cell types, including alveolar epithelial cells, pulmonary vascular endothelial cells, macrophages, neutrophils, and others. There is mounting evidence that these diverse cell populations within the lung interact to regulate lung inflammation in response to both direct and indirect stimuli.

Gestational diabetes mellitus (GDM) is a metabolic disorder that arises during pregnancy and heightens the risk of placental dysplasia. Ginsenoside Re (Re) may stabilize insulin and glucagon to regulate glucose levels, which may improve diabetes-associated diseases. This study aims to investigate the mechanism of Re in high glucose (HG)-induced apoptosis of trophoblasts through endoplasmic reticulum stress (ERS)-related protein CHOP/GADD153.

Nucleotide-binding oligomerization domain protein 1 (NOD1) is one of the innate immune receptors that has been associated with tumorigenesis and abnormally expressed in various cancers. However, the role of NOD1 in Glioblastoma Multiforme (GBM) has not been investigated. We used the Tumor Immune Estimate Resource (TIMER) database to compare the differential expression of NOD1 in various tumors.
