Example sentences for: desensitization
How can you use “desensitization” in a sentence? Here are some example sentences to help you improve your vocabulary:
Cyclic nucleotide-gated channels, for example, appear to exhibit functional dimerization of their cyclic nucleotide-binding domains [ 32 ] . The "RCK" domain of BK channels has a dimerization domain even though BK channels, too, are tetrameric at the level of the pore [ 33 ] . Finally, the GluR2 ligand-binding core has a dimerization interface in the crystal structure [ 34 ] . Evidence, including the clustering of residues involved in receptor desensitization at this interface, suggests that the dimerization is not just crystallographic but functional.
Similarly, mutation of only two serine residues in the human alpha-2A receptor resulted in a loss of desensitization [ 12 ] . Because the EESSSSE motif in the human alpha-2A receptor is a known GRK substrate, and because eliminating two potential phosphorylation sites prevents down-reguation, phosphorylation of the opossum alpha-2C receptor may be important in the mechanism of down-regulation of this receptor.
Mammalian ORs are known to undergo rapid desensitization after odorant stimulation [ 56] and GRK3 has been implicated in this process [ 57, 58].
The predicted topological organization consists of six transmembrane domains with a hydrophobic loop between the fifth and sixth domain which lines the ion conducting pore [ 17 ] . VR1 has been expressed heterologously in several cell lines and has intrinsic sensitivity to thermal stimuli and to capsaicin (a pungent extract of the Capsicum pepper family) [ 18 ] . VR1 does not discriminate among monovalent cations [ 19 ] ; however, it exhibits a notable preference for divalent cations with a permeability sequence of Ca 2+> Mg 2+> Na +≈ K +≈ Cs + [ 9 ] . Ca 2+is especially important to VR1 function, as extracellular Ca 2+mediates desensitization [ 20 21 ] , a process which enables a neuron to adapt to specific stimuli by diminishing its overall response to a particular chemical or physical signal.
The quantity of LH secreted by the anterior pituitary gland is the outcome of an interaction between the amount of hypothalamic GnRH secretion and the level of gonadotrope responsiveness to GnRH [ 7 ] . Quantitatively, gonadotrope responsiveness is more important than the level of GnRH secretion; for example, during the estrogen-stimulated preovulatory surge of LH secretion in the rat there is a 5-fold increase in GnRH secretion but a 50-fold increase in LH secretion [ 7 ] . Moreover, a quantity of GnRH that will evoke a normal preovulatory LH surge during the period preceding ovulation will induce only a small increase in LH secretion at other stages of the estrous cycle [ 7 ] . Similarly, termination of the preovulatory LH surge appears to be due to desensitization of the gonadotrope to GnRH action; in the sheep, a decrease in LH secretion precedes the decrease in GnRH secretion [ 41 ] , whereas in the rat, although the decrease in GnRH and LH secretion are co-incident [ 7 ] , there is evidence that the gonadotrope is already desensitized to GnRH [ 42 43 ] .
