Patrolling monocytes sense peripheral infection and induce cytokine-mediated neuronal dysfunction pp659 - 661

Josef Priller & Chotima Böttcher


A new study reveals that virus-associated activation of a subset of circulating monocytes results in the release of the proinflammatory cytokine tumor necrosis factor (TNF)-α, which induces increased turnover of synapses in the brain and learning deficits in mice.

MSK-IMPACT is a clinical sequencing platform able to detect genomic mutations, copy number alterations and structural variants in a panel of cancer-related genes. This assay is implemented prospectively to inform patient enrollment in genomically matched clinical trials at Memorial Sloan Kettering Cancer Center (MSKCC). Sequencing results of tumor and matched normal tissue from a cohort of >10,000 patients with detailed clinical annotation provide an overview of the genomic landscape of advanced solid cancers and bring new insights into molecularly guided cancer therapy.

CX3CR1+ monocytes modulate learning and learning-dependent dendritic spine remodeling via TNF-α pp714 - 722

Juan Mauricio Garré, Hernandez Moura Silva, Juan J Lafaille & Guang Yang


In a rodent model of viral infection, immune activation causes impairments in motor-learning-dependent cortical synaptic remodeling that are mediated by peripheral monocytes rather than by CNS-resident microglia.

MAFB prevents excess inflammation after ischemic stroke by accelerating clearance of damage signals through MSR1 pp723 - 732

Takashi Shichita, Minako Ito, Rimpei Morita, Kyoko Komai, Yoshiko Noguchi, Hiroaki Ooboshi, Ryusuke Koshida, Satoru Takahashi, Tatsuhiko Kodama & Akihiko Yoshimura


The scavenger receptor MSR1 contributes to the clearance of damage-associated molecular patterns (DAMPs) by infiltrating myeloid cells in the post-stroke rodent brain. Myeloid cell MSR1 deficiency impairs clearance and exacerbates stroke-induced impairments, whereas a pharmacological intervention to boost MSR1 expression improves pathological and functional outcomes.

Pericytes impair capillary blood flow and motor function after chronic spinal cord injury pp733 - 741

Yaqing Li, Ana M Lucas-Osma, Sophie Black, Mischa V Bandet, Marilee J Stephens, Romana Vavrek, Leo Sanelli, Keith K Fenrich, Antonio F Di Narzo, Stella Dracheva, Ian R Winship, Karim Fouad & David J Bennett


In rat models of spinal cord injury, the region of the spinal cord below the site of injury becomes hypoxic owing to inadequate blood flow. This effect on blood flow is due to increased production of neurotransmitters known as ‘trace amines,’ which act on pericytes to constrict blood vessels. Alleviation of hypoxia by hyperoxic breathing or inhibition of trace amine synthesis or action improves locomotor function in the injured rats.
