Migration of lung-infiltrating T cells is correlated and fits a lognormal distribution. GFP⁺ effector T cells were injected i.v. into LPS-treated mice. After two to five days, lungs were explanted and imaged with two-photon microscopy. Tracks with a duration of 120 min were analyzed. a Shown are the cumulative distribution functions (CDF) of experimentally measured speeds from 2960 frame-to-frame migration steps and of the fits of various mathematical models. b Autocorrelation of turning angle. Analyses were performed on 37 tracks pooled from three independent experiments
