Regulated migration of T-lymphocytes through high endothelial venules and secondary lymphoid organs is necessary for an adaptive immune response. Uncontrolled trafficking of T-cells is implicated in many pathological conditions, including autoimmune disorders, such as psoriasis and inflammatory bowel disease. T-cell migration is regulated mainly by the αLβ2 integrin receptor LFA-1, which interacts primarily with its cognate ligand ICAM-1 expressed on the endothelium. This interaction triggers a plethora of downstream signaling pathways, which are not fully understood. Thus, in order to dissect the signal transduction processes at molecular levels and phenotypic changes in migrating T-cells, a laboratory model mimicking T-cell motility is important. Here, we describe a simple and highly reproducible in vitro model to study T-cell migration. |
