Münster. Although the CNS is immune privileged, continuous search for pathogens and tumours by immune cells within the CNS is indispensable. Thus, distinct immune-cell populations also cross the blood–brain barrier independently of inflammation/under homeostatic conditions. It was previously shown that effector memory T cells populate healthy CNS parenchyma in humans and, independently, that CCR5-expressing lymphocytes as well as CCR5 ligands are enriched in the CNS of patients with multiple sclerosis. Apart from the recently described CD8+ CNS tissue-resident memory T cells, CRC researchers from Muenster identified a population of CD4+CCR5high effector memory cells as brain parenchyma-surveilling cells. In an interview with the German radio news channel NDR info they explain these latest insights. Listen to the radio report (in German):
