Advance in understanding of all-solid-state batteries

All-solid-state batteries, a battery design composed of all solid components, have gained attention as the next major advance beyond lithium ion batteries because of their potential to store more energy while being safer ...

Chemists ID possible addiction-free pain reliever

An estimated 1.7 million Americans suffer from substance abuse disorders related to opioid use for pain relief, according to the National Institute on Drug Abuse. This causes an economic burden of more than $78 billion per ...

Opening the black box of dendritic computing

How do nerve cells compute? This fundamental question drives LMU neurobiologists led by Andreas Herz. They have now presented a novel method to disentangle complex neural processes in a much more powerful way than was previously ...

Recipe for safer batteries—just add diamonds

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due ...

Snip, snip, cure—correcting defects in the genetic blueprint

Gene editing using 'molecular scissors' that snip out and replace faulty DNA could provide an almost unimaginable future for some patients: a complete cure. Cambridge researchers are working towards making the technology ...

Improving risk assessment of nano particles as food additives

The anticaking agent E551 silicon dioxide, or silica, has been used widely in the food industry over the past 50 years, and was long thought to be quite safe. Now, however, researchers working on the National Research Programme ...

Brain-imaging system uses 'multi-pupil' prism arrays

A specialized type of adaptive-optics technology that has been demonstrated by taking high-resolution time-lapse images of functioning brain cells might be used to better understand how the brain works.

Dendritic cell

Dendritic cells (DCs) are immune cells that form part of the mammalian immune system. Their main function is to process antigen material and present it on the surface to other cells of the immune system, thus functioning as antigen-presenting cells.

Dendritic cells are present in small quantities in tissues that are in contact with the external environment, mainly the skin (where there is a specialized dendritic cell type called Langerhans cells) and the inner lining of the nose, lungs, stomach and intestines. They can also be found in an immature state in the blood. Once activated, they migrate to the lymphoid tissues where they interact with T cells and B cells to initiate and shape the adaptive immune response. At certain development stages they grow branched projections, the dendrites, that give the cell its name. However, these do not have any special relation with neurons, which also possess similar appendages. Immature dendritic cells are also called veiled cells, in which case they possess large cytoplasmic 'veils' rather than dendrites.
