Formation of a microspike, a thin, stiff projection extended from the surface of a migrating cell.

actin cytoskeleton organization and biogenesis

actin cytoskeleton organisation and biogenesis

The assembly and arrangement of cytoskeletal structures comprising actin filaments and their associated proteins.

A type of intermediate filament, typically made up of one or more of the proteins vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Unlike the keratins, the type III proteins can form both homo- and heteropolymeric IF filaments.

The rapid expansion of a neuroblast population by cell division. Neuroblasts are embryonic cells which develop into nerve cells or neurons. As in, but not restricted to, the vertebrates (Vertebrata, ncbi_taxonomy_id:7742).

Processes by which a myeloid precursor cell acquires specializes features of an erythrocyte without a nucleus, as found in mammals.

Catalysis of the reaction: 5-alpha-cholest-7-en-3-beta-ol + O2 = cholesta-5,7-dien-3-beta-ol + H2O2.

Catalysis of the reaction: biotin amide + H2O = biotin + NH3.

Catalysis of the reaction: L-pipecolate + O2 = 2,3,4,5-tetrahydropyridine-2-carboxylate + H2O2.

The process of elimination of immature T cells in the thymus which react strongly with self-antigens.

The chemical reactions involving S-adenosylhomocysteine; the L-enantiomer is formed from S-adenosylmethionine and is a strong inhibitor of S-adenosylmethionine-mediated methylation reactions. It can be cleaved to form adenosine and homocysteine.

Processes of T cell selection that occur in the thymus.

The directed movement of metal ions, any metal ion with an electric charge, into, out of, within or between cells.

Processes of T cell selection that occur in extrathymic locations, often resulting T cells of distinct specificities from those selected in the thymus.

The regulation of the levels, transport, and metabolism of anions within a cell or between a cell and its external environment.

The process whereby a relatively unspecialized T cell acquires the specialized features of a Th1 cell.
