Immune Cell Internalizing Sugar Granules

A new microscope developed at Howard Hughes Medical Institute's Janelia Research Campus is pushing the limits of optical imaging of living organisms. The system combines adaptive optics, a technique commonly used in astronomy to eliminate distortions, with lattice light-sheet microscopy to produce high-speed, super-resolution imagery of cellular dynamics.

Here, a neutrophil (white blood cell) can be seen internalizing small granules of sugar via phagocytosis within a developing zebrafish embryo. The larva has been genetically modified to express the fluorescent protein Citrine in the plasma membrane of all its cells. Dextran particles labeled with the fluorophore Texas Red were injected into the blood stream and then imaged as they prompted an immune response.

This extraordinary view of cellular behavior within a living organism is one of many remarkable videos reported in Science last week alongside the new microscope.

Young people should try to avoid excessive simple #sugar by eliminating the most common sources of consumption like sugared soft drinks, breakfast cereals with added sugar and adding table sugar to foods. Excessive sugar intake has been linked to #obesity and diabetes, both of which contribute to heart disease. Sugar represents “empty calories” with none of the important #nutrients needed in a balanced diet.

Are sweeteners healthier than sugar? Public Health England wants our sugar intake to be cut by a fifth by 2020.

Artificial sweeteners, such as Xylitol, give a sweet taste with few or no calories.

But are they healthier? https://bbc.in/2IImK2S
