Apoptosis

... and published in Science Online in December, 2001. Albert described how dendritic Cells, a type of antigen-presenting cells, phagocytose (that is, engulf) apoptotic tumor cells. Upon maturation, these dendritic cells present antigen (derived from the apoptotic corpses) to killer T ...

Immune system

... cells (APCs). A major category of APCs involved in T cell activation, the dendritic cells , are part of the innate immune system. Activation occurs when a DC ... by T cells that are all belonging to the adaptive immune system. But the dendritic cells are often directly activated by engaging their toll like receptors ...

Major histocompatibility complex

... a risk of contagion for neighboring cells. Mhc Class II molecules are found only on a few specialized cell types, including macrophages , dendritic cells , activated T cells , and B cells , which may be referred to collectively as "antigen-presenting cells" (APCs). Class II molecules are also ...

Neuron

... with many target cells. The dendrite , a short, branching arbor of cellular extensions. Each neuron has very many dendrites with profuse dendritic branches. These structures form the main information receiving network for the neuron. Axon and dendrites alike are typically only about a ...

Synapse

... Integration of synaptic inputs 5 Detailed properties and regulation 6 References Anatomy At a prototypical synapse, such as a dendritic spine , a mushroom-shaped bud projects from each of two cells and the caps of these buds press flat against one another. At this interface, the ...
