Adhesion characteristics of LAD-III T lymphocytes expressing WT kindlin-3. (A) Differential interference contrast (DIC), GFP, and IRM images of the patient T lymphoblasts transfected with GFP (top panel) and mouse GFP-kindlin3 cDNAs (middle panel) compared with the GFP-transfected control T lymphoblasts (bottom panel). Images are representative of 11-15 cells; n = 3. (B) Quantification of the area of close contact of the same cells; n = 11 cells per group.
