In previous studies on platyhelminths, the effects of peptide modulators of the neuromuscular system have been examined on muscle strips or dispersed muscle fibres. Therefore, it probably only metabolizes the released peptide. However, the short peptides did not encompass any sequence characteristic for functional domains of cysteine proteases. Cellular uptake of an alpha-helical amphipathic model peptide with the potential to deliver polar compounds into the cell interior non-endocytically. Identification of regions involved in the binding of alpha-bungarotoxin to the human alpha7 neuronal nicotinic acetylcholine receptor using synthetic peptides. Above a threshold concentration, the peptide disrupts the lipid packing, which leads to the internalization of the peptide. Finally, oxytocin's effects on maternal bonding can be disrupted via blockade of m-opiod receptors, underscoring the relation between oxytocin and opioid peptides. These two peptides seemed to be products of prestressed protoscoleces. It turns out that amphipathicity simply prevented peptide washout, but was not essential for the internalization. Antimicrobial peptide pores in membranes detected by neutron in plane scattering. They created aggregates of simple polyglutamine peptides in vitro and introduced them to mammalian cells in culture. Cellular import of functional peptides to block intracellular signaling. These examples are from corpora and from sources on the web.
