The adhesion of one erythrocyte to one or more other erythrocytes via adhesion molecules.

The formation of a protein trimer, a macromolecular structure consisting of three noncovalently associated identical or nonidentical subunits.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a virus.

The process in which a signal is passed on to downstream components within the cell through the NIK-dependent processing and activation of NF-KappaB. Begins with activation of the NF-KappaB-inducing kinase (NIK), which in turn phosphorylates and activates IkappaB kinase alpha (IKKalpha). IKKalpha phosphorylates the NF-Kappa B2 protein (p100) leading to p100 processing and release of an active NF-KappaB (p52).

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.

A secretory vesicle that is stored under the cell membrane of an egg. These vesicles fuse with the egg plasma membrane as part of egg activation and are part of the block to polyspermy.

The nucleus of the female germ cell, a reproductive cell in females.

The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A dimer consisting of an alpha and a beta-subunit that imports proteins with an NLS into the nucleus through a nuclear pore.

A secretory vesicle that is stored under the cell membrane of an egg. These vesicles fuse with the egg plasma membrane as part of egg activation and are part of the block to polyspermy.

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

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

The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

The enlarged, fluid filled nucleus of a primary oocyte, the development of which is suspended in prophase I of the first meiotic division between embryohood and sexual maturity.

The enlarged, fluid filled nucleus of a primary oocyte, the development of which is suspended in prophase I of the first meiotic division between embryohood and sexual maturity.

The space between the membrane of an oocyte and a surrounding membranous structure (zona pellucida or perivitelline membrane).

The space between the membrane of an oocyte and a surrounding membranous structure (zona pellucida or perivitelline membrane).

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

The nucleus of the female germ cell, a reproductive cell in females.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

An organelle found in cnidoblast (nematoblast) cells. When matured, these stinging organelles store toxins and can deliver them when the cnidocil (a short extension of the cnidocyst) is stimulated by a prey or another stimulus.

A dimer consisting of an alpha and a beta-subunit that imports proteins with an NLS into the nucleus through a nuclear pore.
