TLDR
Recent observations on the impact of dysregulated cytokine networks in neuroinflammation are summarized.Abstract:
Cytokines provide cells with the ability to communicate with one another and orchestrate complex multicellular behaviour. There is an emerging understanding of the role that cytokines play in normal homeostatic tissue function and how dysregulation of these cytokine networks is associated with pathological conditions. The central nervous system (CNS), where few blood-borne immune cells circulate, seems to be particularly vulnerable to dysregulated cytokine networks. In degenerative diseases, such as proteopathies, CNS-resident cells are the predominant producers of pro-inflammatory cytokines. By contrast, in classical neuroinflammatory diseases, such as multiple sclerosis and encephalitides, pro-inflammatory cytokines are mainly produced by tissue-invading leukocytes. Whereas the effect of dysregulated cytokine networks in proteopathies is controversial, cytokines delivered to the CNS by invading immune cells are in general detrimental to the tissue. Here, we summarize recent observations on the impact of dysregulated cytokine networks in neuroinflammation.read more

TL;DR: High‐dimensional cytometry reveals that microglia, several subsets of border‐associated macrophages and dendritic cells coexist in the CNS at steady state and exhibit disease‐specific transformations in the immune microenvironment during aging and in models of Alzheimer’s disease and multiple sclerosis.

An Inflammation-Centric View of Neurological Disease: Beyond the Neuron.
TL;DR: This review will describe the current state of knowledge concerning the biology of neuroinflammation, emphasizing mast cell-glia and glia- glia interactions, then conclude with a consideration of how a cell's endogenous mechanisms might be leveraged to provide a therapeutic strategy to target neuro inflammation.

The Meningeal Lymphatic System: A New Player in Neurophysiology.
TL;DR: The meningeal lymphatic system can be viewed as a novel player in neurophysiology by altering the accessibility of CSF-borne immune neuromodulators to the brain parenchyma, thereby altering their effects on the brain.

TL;DR: It is suggested that mast cell-associated inflammatory mediators from systemic inflammation and brain could augment neuroinflammation and neurodegeneration in the brain.

TL;DR: A single-cell characterization of cerebrospinal fluid and blood of newly diagnosed multiple sclerosis patients is provided, revealing altered composition of lymphocyte and monocyte subsets, validated by other methods including the interrogation of the TFH subset in mouse models of MS.

TL;DR: Elevated circulating TNF may be derived from the local CNS inflammatory reaction in AD, and may account for some systemic manifestations of AD such as weight loss.

TL;DR: Key activities for GM-CSF are revealed in the development of inflammatory demyelinating lesions and control of migration and/or proliferation of leukocytes within the CNS, which hold implications for the pathogenesis of inflammatory and demYelinating diseases.

TL;DR: It is shown that in both mice and humans, interleukin-34 (IL-34), an alternative ligand for Csf-1 receptor, is produced by keratinocytes in the epidermis and by neurons in the brain.

What is the blood–brain barrier (not)?
TL;DR: The BBB is re-define as a capillary barrier for solutes, and it is clarified that leukocyte recruitment requires two differentially regulated steps: passage across postcapillary venules into Virchow-Robin spaces, and subsequent progression across the glia limitans into the neuropil.
