In this issue of Neuron, Takeo et al. (2021) manipulate synaptic organizers GluD2 and cerebellin-1 to show that Purkinje cells regulate how their dendrites branch by competing with neighboring cells for synaptic real estate.

DCs are bone marrow ( BM) -derived Dendritic cells are the first antigen-presenting cells usually to encounter parasites and helminth modulation of DC function has been well characterized. 41 Filarial parasites induce downregulation of MHC class I and class II as well as cytokines and other genes involved in antigen presentation, thereby rendering DCs suboptimal in activation of CD4 T cells. Nerve cells (neurons) have extensive processes called dendrites. These occupy a large surface area of a neuron. They receive many signals from other neurons and contain specialized proteins that receive, process, and transfer these to the cell body. Dendrites, also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project. Electrical stimulation is transmitted onto dendrites by upstream neurons via synapses which are located at various points throughout the dendritic tree.

Actually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle.
Presenting LUCC Researchers: Targeting of Dendritic Cells
Neurons communicate with each other through an electrochemical process. Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters). 2020-07-17 · B cells have special receptors that bind to one type of antigen. These cells differentiate and mature inside the spleen but are naïve.
Dendritic cells (DCs) are antigen-presenting cells derived from bone marrow precursors and form a widely distributed cellular system throughout the body. DCs exert immune-surveillance for exogenous and endogenous antigens and the later activation of naive T lymphocytes giving rise to various immunological responses. Different growth factors and cytokines can modulate the differentiation and
Dendritic cells are central to the initiation of primary immune responses. They are the only antigen-presenting cell capable of stimulating naive T cells, and hence they are pivotal in the generation of adaptive immunity. Dendritic cells also interact with and influence the response of cells of the …
Dendrites bring electrical signals to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process. Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).
Dendrites now are known to contribute their own electrical charge to the current. These are called dendritic spikes and travel from a dendrite into the extremely large, dense and complex dendritic arbor.
Dendritic cells (DC) are a heterogeneous family of cells that function as sentinels of the immune system. This article summarizes observations suggesting that inflammatory chemokines secreted at the site of pathogen invasion determine the DC subset recruited and influence the class of the immune response initiated. Dendritic cells (DCs) initiate and maintain adaptive T helper 2 (Th2) cell responses to inhaled allergens in asthma.

initiation. • stage 1: "spherical" neuron • stage 2: neurons extend several neurites • stage 3: one neurite accelerates its growth rate and matures to form the axon. • stage 4: dendrites begin to elongate and branch • stage 5: synaptogenesis. polarization and maturation. Dendrites have ion channels that are similar to axons, dependent on electrical charge and voltage. Dendrites now are known to contribute their own electrical charge to the current.
