In MS, immune cell infiltration is predominantly localised in focal white matter lesions.
More specifically, PD-L1+ melanoma cells were almost always localised immediately adjacent to tumour-infiltrating lymphocytes (TILs), while tumours with minimal TIL infiltration were less likely to express PD-L1.
Midline localisation, periumbilical or poorly localised 2.
The inflammatory infiltration consisted of single lymphocytes mainly localised subendocardially.
25 27 Such a response in vivo would trigger local infiltration and activation of leucocytes and contribute to localised inflammation.
Malignant infiltration of the muscles on the other hand is more localised and lower in signal intensity.
The present study localised a broad range of individual basement membrane components and also observed islets before and after lymphocyte infiltration where the basement membrane was observed to be present or absent, respectively.
Pavin et al. [ 9] localised laminin around the islets of NOD mice and found disruption of the peri-islet basement membrane associated with intense infiltration by inflammatory cells.
In addition, numbers of CD8+ lymphocytes were found to be localised in the extravascular TDG treated tumor tissue, occurring in regions of tumor adjacent to the tumor vasculature, indicating increased tumor infiltration by these lymphocytes.
