What is a Dentrite: The word dendrite derived from the Greek word "Dendron", which means the 'tree' or the 'branched such as e tree'. Vaccines by definition are biological agents that elicit an immune response to a specific antigen derived from an infectious disease-causing pathogen. Define dendritic cell. Dendritic cells are named after their shape and are not neurons with dendrites, as was thought when first discovered in the late nineteenth century. 2. Dendritic cell: A special type of cell that is a key regulator of the immune system, acting as a professional antigen-presenting cell (APC) capable of activating naïve T cells and stimulating the growth and differentiation of B cells. The functions of dendrites are to . The information transfer is usually received at the dendrites through . The cells are irregular in shape with phase-dense granules, an irregular nucleus, and a small nucleolus. Dendrites allow the most complex interconnection between nerve cells, as in the brain, so that elaborate control arrangements over the passage of nerve impulses are made possible. Dendritic cells (DCs) are antigen-presenting cells (also known as accessory cells) of the mammalian immune system.Their main function is to process antigen material and present it on the cell surface to the T cells of the immune system. Dendrites allow the most complex interconnection between nerve cells, as in the brain, so that elaborate control arrangements over the passage of nerve impulses are made possible.

They are innate immune cells as they can recognize pathogens, but they can also prepare and present antigens in the context . Definition. dendritic spines: variably long excrescences of nerve cell dendrites, varying in shape from small knobs to thornlike or filamentous processes, usually more numerous on distal dendrite arborizations than on the proximal part of dendritic trunks. Dendritic spines are a preferential site of synaptic axodendritic contact; they are sparse or absent in some types of nerve cells (motor neurons, the large cells of the globus pallidus, and stellate cells of the cerebral cortex), and exceedingly numerous in others such as the pyramidal cells of the cerebral cortex and the Purkinje cells of the cerebellar cortex.

As an APC, a dendritic cell can retain antigen for long periods on its surface, present . 2.6). dendritic cell. and Na+ channels (Ca vs, Na vs) and NMDA receptors (NMDARs) that can amplify locally suprathreshold electrical signals and thus, generate dendritic spikes in many neuron types. Major subsets of MDSC: Appearances matter. Initially, MDSC in mice were defined as cells expressing a Gr-1 + CD11b + phenotype and lacking the expression of markers typical of mature macrophages (MΦ) and dendritic cells (DC) [18, 19].In humans, MDSC were defined as cells that co-purified with mononuclear cells, lacked markers of lymphocytes, natural killer cells, monocytes, and DC, and . Dendrites (from Greek Î´Î­Î½Î´Ï Î¿Î½ déndron, "tree") (also dendron) are the branched projections of a neuron that act to propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project. The ease with which they can be grown in laboratories . Dendritic spines are the most excitatory connection sites in the central nervous system, and changes in the density and/or morphology of prefrontal cortical dendritic spines are a common feature of the human condition and associated animal patterns characterized by impaired cognitive and social behavior [66, 67]. 2).Dendritic spines represent sites of synaptic contact and primarily comprised of polymerized actin or filamentous actin.
