A framework for characterizing dendritic cells

Immunological sentinels known as dendritic cells (DCs) help the body eliminate a wide variety of potential threats, from pathogens to cancer—but they are not all created equal. Some DCs are better at fighting bacteria, ...

T cells support long-lived antibody-producing cells

If you've ever wondered how a vaccine given decades ago can still protect against infection, you have your plasma cells to thank. Plasma cells are long-lived B cells that reside in the bone marrow and churn out antibodies ...

New software automates brain imaging

When humans and animals learn and form memories, the physical structures of their brain cells change. Specifically, small protrusions called dendritic spines, which receive signals from other neurons, can grow and change ...

Anti-viral rapid reaction force

After host cells have been attacked by a virus, they present parts of the pathogen on their surface. Thanks to these virus components, the killer cells patrolling in the body (CD8+ T lymphocytes) can recognise the infected ...

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.
