- static microtubule bundle
A microtubule bundle that has a constant length, and in which microtubule sliding does not take place.
- homoiothermy
Any homoeostatic process in which an organism maintains its internal body temperature at a relatively constant value. This is achieved by using metabolic processes to counteract fluctuations in the temperature of the environment.
- obsolete auxin homeostasis
OBSOLETE. A homeostatic process that maintains an endogenous steady-state concentration of primary auxin, or constant level of auxin in a biological system, by a number of biochemical processes including transport, biosynthesis, catabolism and conjugation.
- septate junction
A cell-cell junction that forms a continuous band around each cell in an epithelium; within the septate junction the membranes of adjacent cells maintain a constant distance of approximately 15 nm; found in arthropods.
- isotype switching
The switching of activated B cells from IgM biosynthesis to biosynthesis of other isotypes of immunoglobulin, accomplished through a recombination process involving an intrachromosomal deletion involving switch regions that reside 5' of each constant region gene segment in the immunoglobulin heavy chain locus.
- isotype switching to IgE isotypes
The switching of activated B cells from IgM biosynthesis to IgE biosynthesis, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and IgE constant region gene segments in the immunoglobulin heavy chain locus.
- isotype switching to IgD isotypes
The switching of activated B cells from IgM biosynthesis to IgD biosynthesis, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and IgD constant region gene segments in the immunoglobulin heavy chain locus.
- Fc receptor mediated stimulatory signaling pathway
The series of molecular signals generated as a consequence of a the binding of the Fc portion of an immunoglobulin by an Fc receptor capable of activating or perpetuating an immune response. The Fc portion of an immunoglobulin is its C-terminal constant region.
