Example sentences for: agrin

How can you use “agrin” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In order to examine the possible interactions between agrin and LN1, combination experiments were conducted in which the total exposure time to individual stimuli was less than or equal to 24 hours.

  • [ 5 ] . BDNF transiently stabilizes silent NM synapses during the period of transition from polyneuronal to mononeuronal innervation of skeletal muscle fibers [ 6 ] . BDNF and CNTF cooperatively affect efficiency of embryonic xenopus neuromuscular synapses in culture [ 7 8 ] . BDNF stimulates transmitter release from neuromuscular synapses [ 9 ] and enhances the efficiency of transmission at the neuromuscular synapse [ 10 ] . BDNF, together with NT-3, can restore neuregulin levels and a normal distribution of AchR at the neuromuscular junction blocked with curare [ 11 ] . BDNF, in conjunction with fibronectin, increases spontaneous synaptic currents in the cultured embryonic xenopus neuromuscular junction [ 12 ] . BDNF down-regulates AchR clustering, most likely by binding to TrkB expressed in myocytes [ 13 ] . BDNF downregulates agrin levels in muscle but increases neuregulin in ventral horn spinal motor neurons at the time when they form neuromuscular synapses [ 14 ] .

  • Agrin dramatically increased the proximity of receptor aggregates, while laminin stimulation resulted in random distributions of aggregates.

  • This is based on aggregation assays showing different time courses, additive dose response relationships, and differential co-localization of the dystrophin complex, and on biochemical observations indicating the lack of requirement for MuSK, and the lack of tyrosine-phosphorylation of receptors during LN1 but not agrin induced aggregation [ 1 2 4 ] . The very minimal receptor aggregation seen in agrin deficient mice certainly argues that laminins are not sufficient to trigger receptor aggregation [ 5 ] . More recently we have shown that agrin and LN1 induced aggregates can also be differentiated on the basis of the ultrastructural arrangement of receptors within aggregates [ 6 ] .

  • Accordingly the question arises as to how this approach can be compared with previous studies which demonstrate a visible colocalization of AChRs and α-DG in muscle cells stimulated by nerve terminals [ 19 ] or agrin [ 4 20 26 27 ] . First we note that the present results do support a significant colocalization of the two molecules in agrin stimulated cells as compared to controls (Figure 5), in general agreement with previous findings.
