An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.

Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.

The process whose specific outcome is the progression of nervous tissue over time, from its formation to its mature state.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that activates or increases the rate or extent of cell proliferation.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

The process in which a relatively unspecialized cell acquires the specialized features of a glial cell.

Any process that modulates the frequency, rate or extent of signal transduction mediated by the phosphatidylinositol 3-kinase cascade.

Any process that modulates the frequency, rate or extent of gene expression as a consequence of a process in which a signal is released and/or conveyed from one location to another.

A series of molecular signals in which a cell uses a phosphatidylinositol-mediated signaling to convert a signal into a response. Phosphatidylinositols include phosphatidylinositol (PtdIns) and its phosphorylated derivatives.

The process whose specific outcome is the progression of a cranial ganglion over time, from its formation to the mature structure.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
