Directional migration of T-lymphocytes is a key process during immune activation and is tightly regulated both temporally and spatially. The initial cell membrane protrusion at a particular site is critical for determining the direction of cell migration. In this study, we found that ZAP-70 protein appeared not only at the margin of the spreading areas of polarized Jurkat T cells but also formed clusters...
Aberrant lymphocyte infiltration is crucial for many disorders such as tumor immune escape and autoimmunity. In this study, we have investigated T-cell migration in a three-dimensional collagen matrix containing tumor spheroids and by using μ-Slide chemotaxis and found that Zap70 regulates directionality during cell chemotaxis. Jurkat cells actively migrated toward SDF-1, nutrition, and spheroids...
