Reduced levels of TJs due to BBB dysfunction lead to pericyte degeneration causing infiltration of antibodies (IgG), intercellular adhesion molecule (ICAM-1/2/vascular cell adhesion molecules (VCAM), thrombin, plasminogen, haemoglobin (Hb) and iron (II) released from RBCs further produce ROS in the matrix, toxic for motor neurons in case of ALS.
