Although the requirement of membrane cholesterol for ligand binding to 5-HT1A receptors [23], and other G-protein-coupled receptors [41] has been demonstrated earlier, the present results constitute the first observation where the availability of free cholesterol rather than its mere physical presence in the membrane is essential for receptor function.
Sample text:```The ¬¨¬µ-opioid receptor agonist morphine also induced inhibitory effects in both assays, in accordance with previous reports describing the opiate-mediated inhibition of the BSL evoked in mice by excitatory amino acids and neurokinins (Aanonsen et al. 1987; Takahasi et al. 1987; Wilcox 1988).```
Sample intent: result
Sample text:```Intriguingly, using MPRs-deficient MEF cells, mouse and human CLN5 have been shown to reach lysosomes in an MPRindependent manner [12].```

Sample text:```The extracellular region of SIRPα interacts with its ligand, CD47, which is also a member of the Ig superfamily,(19,20,24) with such interaction promoting the tyrosine phosphorylation of SIRPα.(20,25) In contrast to the relatively restricted distribution of SIRPα, CD47 is expressed in most cell types including a variety of hematopoietic cells.```
