The change in morphology and behavior of a dendritic cell resulting from exposure to a cytokine, chemokine, cellular ligand, pathogens, or soluble factor.

The change in morphology and behavior of a microglial cell resulting from exposure to a cytokine, chemokine, cellular ligand, pathogen, or soluble factor.

Catalysis of the reaction: H2O + peptidyl-L-lysine (or L-arginine) = L-lysine (or L-arginine) + peptide (preferential release of a C-terminal lysine or arginine amino acid).

A change in the morphology or behavior of a cell resulting from exposure to an activating factor such as a cellular or soluble ligand.

The process of regulating the proliferation and elimination of cells of the immune system such that the total number of cells of a particular cell type within a whole or part of an organism are stable over time in the absence of an outside stimulus.

The processes by which an organism enters and maintains a periodic, readily reversible state of reduced awareness and metabolic activity. Usually accompanied by physical relaxation, the onset of sleep in humans and other mammals is marked by a change in the electrical activity of the brain.

Feeding behavior in a fully developed and mature organism.

The breakdown into simpler components of unfolded or misfolded proteins transported from the endoplasmic reticulum and targeted to cytoplasmic proteasomes for degradation.

Any process preventing the degeneration of the photoreceptor, a specialized cell type that is sensitive to light.

The chemical reactions involving quinone cofactors.

The orderly movement of glial cells, non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system.

Interacting selectively with any chemokine receptor.

MAP kinase kinase kinase kinase activity

Catalysis of the phosphorylation of serine and threonine residues in a mitogen-activated protein kinase kinase kinase (MAPKKK), resulting in activation of MAPKKK. MAPKKK signaling pathways relay, amplify and integrate signals from the plasma membrane to the nucleus in response to a diverse range of extracellular stimuli.
