The neuroimmune connectome in health and disease Wheeler, Michael A.; Quintana, Francisco J. The nervous and immune systems have complementary roles in the adaptation of organisms to environmental changes. However, the mechanisms that mediate crosstalk between the nervous and immune systems...

Abstract: Hepatic encephalopathy, defined as neuropsychiatric dysfunction secondary to liver disease, is a frequent decompensating event in cirrhosis. Its clinical impact is highlighted by a notable increase in patient mortality rates and a concomitant reduction in overall quality of life...

Myocardial infarction augments sleep to limit cardiac inflammation and damage Huynh, Pacific et 36 al. Sleep is integral to cardiovascular health. Yet, the circuits that connect cardiovascular pathology and sleep are incompletely understood. It remains unclear whether cardiac injury influences...

Long COVID elevated MMP-9 and release from microglia by SARS-CoV-2 Spike protein Duraisamy Kempuraj; Irene Tsilioni; Kristina K. Aenlle; Nancy G. Klimas; Theoharis C. Theoharides OBJECTIVES Long COVID is a major health concern because many patients develop chronic neuropsychiatric symptoms, but...

Spinal cord microglia drive sex differences in ethanol-mediated PGE2-induced allodynia Alexander; Reed; Burton The mechanisms of how long-term alcohol use can lead to persistent pain pathology are unclear. Understanding how earlier events of short-term alcohol use can lower the threshold of...

Microglia rescue neurons from aggregate-induced neuronal dysfunction and death through tunneling nanotubes Hannah Scheiblich; Frederik Eikens; Lena Wischhof; Sabine Opitz; Kay Jüngling; Csaba Cserép; Susanne V. Schmidt; Jessica Lambertz; Tracy Bellande; Balázs Pósfai; Charlotte Geck; Jasper...

SUMMARY Microglia are implicated in all stages of multiple sclerosis (MS). Microglia alterations are detected by positron emission tomography in people living with MS prior to the formation of structural lesions determined through magnetic resonance imaging. In histological specimens, clusters...

Mast cell activation triggered by SARS-CoV-2 causes inflammation in brain microvascular endothelial cells and microglia Wu, Meng-Li; Xie, Chengzuo; Li, Xin; Sun, Jing; Zhao, Jincun; Wang, Jian-Hua SARS-CoV-2-induced excessive inflammation in brain leads to damage of blood-brain barrier...

The S1 subunits of SARS-CoV-2 variants differentially trigger the IL-6 signaling pathway in human brain endothelial cells and downstream impact on microglia activation Michael Stangis; Daniel Adesse; Bhavya Sharma; Eduardo Castro; Kush Kumar; Neil Kumar; Masha Minevich; Michal Toborek...

Abstract Sustained smouldering, or low-grade activation, of myeloid cells is a common hallmark of several chronic neurological diseases, including multiple sclerosis1. Distinct metabolic and mitochondrial features guide the activation and the diverse functional states of myeloid cells2...

Full title: Infection-induced vascular inflammation in COVID-19 links focal microglial dysfunction with neuropathologies through IL-1/IL-6-related systemic inflammatory states Abstract COVID-19 is associated with diverse neurological abnormalities, which predict poor outcome in patients...
