The metabolism of a cell is an intriguing dynamic workflow of metabolites and enzymes that adapt to the needs of each cell in a certain environment. At the end of the day, the main goal of the cell is to produce enough ATP to supply autocrine needs and paracrine or endocrine secretion of different t...

The understanding of how different cell types adapt their metabolism in the face of challenges has been attracting the attention of researchers for many years. Recently, immunologists also started to focus on how the metabolism of immune cells can impact the way that immunity drives its responses. T...

MitoTracker ® dyes are fluorescent compounds that allow cellular mitochondrial content to be measured semi‐quantitatively by flow cytometry and have been used extensively in immunology publications. However, the parameters commonly reported, mean or median fluorescence intensity and percentage of ce...

The fluorescence viewing of mitochondria is commonly performed by MitoTracker, a lipophilic cationic dye that is taken up by the mitochondria. In this forum, we highlight several issues that may occur with MitoTracker, including staining of other organelles. Our aim is to offer alternative dyes and ...

Hematopoietic stem cells (HSCs) are self-renewing, multi-potent, and capable of giving rise to all the cells of the blood1,2. Cellular metabolism is a key regulator of HSC maintenance, along with transcriptional factors, intrinsic signals and the microenvironment3,4,5. The proper control of mitochon...

Mitochondria, the powerhouse of the cell, are known to remodel their membrane structures through the process of fusion or fission. Studies have indicated that T cells adopt different energy metabolic phenotypes, namely oxidative phosphorylation and glycolysis depending on whether they are naïve, eff...

Properly assessing mitochondrial health is crucial to understand their role in disease. MitoTracker green (MTG) and nonylacridine orange (NAO) are fluorescent probes which have been commonly used to assess mitochondrial mass. This is based on the assumption that both MTG and NAO accumulate in mitoch...
