21. Gliotransmission can also occur between two types of glial cells : astrocytes and microglia . 22. Within the brain, quinolinic acid is only produced by activated microglia and macrophages. 23. Microglia and macrophages produce the vast majority of quinolinic acid present in the body.24. Microglia are immune cells for the spinal cord.25. IDO-1, IDO-2 and TDO are present in microglia and macrophages. 26. Glial cells ) and activation of the microglia ( another type of glial cell ). 27. At the final stage of the process, these microglia develop into active demyelinating MS lesion 28. When microglia are activated they take on an amoeboid shape and they alter their gene expression. 29. Infected microglia contain viral particles intracellularly. 30. CCR5 is predominantly expressed on T cells, macrophages, dendritic cells, eosinophils and microglia .
