| 21. | Secondly, perforin permits delivery of the cytotoxic granzymes A and B into target cells.
|
| 22. | Natural hormones connect with receptors and switch on or off functions within target cells.
|
| 23. | Cytotoxic drugs administered during chemotherapy target cells with fast turnovers such as malignant cells.
|
| 24. | In addition to killing their target cells, granzymes can target and kill intracellular pathogens.
|
| 25. | This mode of transport increases virulence by aiding in EHEC-Hly delivery to target cells.
|
| 26. | There also seems to be a link between IFN-? production and killing of target cells.
|
| 27. | When HIV infects its target cell it requires fusion of the viral and cellular membranes.
|
| 28. | Synaptic signaling, an integral part of nervous system activity, occurs between neurons and target cells.
|
| 29. | These channels disrupt the cell membrane of target cells, leading to cell lysis and death.
|
| 30. | So neurons that are quiet when others throb lose their grip on the target cell.
