The brain is less immune-priviledged than we thought
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 […]...more

Featured Publication: Integrated single cell analysis of blood and cerebrospinal fluid leukocytes in multiple sclerosis
Münster. Cerebrospinal fluid (CSF) protects the central nervous system (CNS) and analyzing CSF aids the diagnosis of CNS diseases, but our understanding of CSF leukocytes remains superficial. Here, using single cell transcriptomics, SFB researchers identify a specific border-associated composition and transcriptome of CSF leukocytes. In an article published in Nature Communications, they show that multiple […]...more

Wed, 23/11/2016 | Featured publication: Imaging matrix metalloproteinase activity in multiple sclerosis as a specific marker of leukocyte penetration of the blood-brain barrier

Münster – The enzymes gelatinase A/matrix metalloproteinase-2 (MMP-2) and gelatinase B/MMP-9 are essential for induction of neuroinflammatory symptoms in experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis (MS). In the absence of these enzymes, the disease does not develop. SFB128 scientists of Prof. Dr. Lydia Sorokin’s group, therefore, investigated the cellular sources and relative contributions of MMP-2 and MMP-9 to disease at early stages of EAE induction. They demonstrated that MMP-9 from an immune cell source is required in EAE for initial infiltration of leukocytes into the central nervous system and that MMP-9 activity is a reliable marker of leukocyte penetration of the blood-brain barrier.
The neuroscientists then developed a molecular imaging method to visualize MMP activity in the brain using fluorescent- and radioactive-labeled MMP inhibitors (MMPis).
By using radioactive MMP ligand in EAE animals the Muenster neuroscientists produced positron emission tomography (PET) images of MMP activity in patients with MS.
In contrast to traditional T1-gadolinium contrast-enhanced MRI, MMPi-PET enabled tracking of MMP activity as a unique feature of early lesions and ongoing leukocyte infiltration.
MMPi-PET therefore allows monitoring of the early steps of MS development and provides sensitive, noninvasive means of following lesion formation and resolution in murine EAE and human MS, the neuroscientists conclude. Their work was part of the SFB projects B03 and Z02.
