Spatial heterogeneity of the myeloid compartment within a single tissue section of a patient with encephalitis revealed by P2RY12 and TMEM119 immunohistochemistry. The immunohistochemical reactions for P2RY12 (brown, upper panel) and TMEM119 (brown, lower panel) are shown in two regions of the same tissue section of a patient with encephalitis. The microglia cells (as identified by P2RY12) positivity show a downregulation/loss of TMEM119 upon activation. Counterstaining with haematoxylin (blue). Scale bar: 100 µm
