ABSTRACT Reciprocal communication between the brain and the immune system is essential for maintaining lifelong brain function. This interaction is mediated, at least in part, by immune cells recruited from both the circulation and niches at the borders of the brain. Here, we describe … Read more

ABSTRACT Circulating immune cells contribute to the pathogenesis of Alzheimer’s disease (AD), but their role is poorly understood. Rosenzweig et al. recently identified a subset of interleukin (IL)-17+ neutrophils that inhibit neuroprotective microglia in female APOE4 carriers. Blockade of IL-17 signaling or APOE4 deletion … Read more

ABSTRACT Neural cells in our central nervous system (CNS) have long been thought to be mere targets of neuroinflammatory events in neurodegenerative diseases such as multiple sclerosis (MS) or Alzheimer’s disease. While glial populations such as microglia and astrocytes emerged as active responders and … Read more

ABSTRACT The importance of neuroinflammation in neurodegenerative diseases is becoming increasingly evident, and, in parallel, human induced pluripotent stem cell (hiPSC) models of physiology and pathology are emerging. Here, we review new advancements in the differentiation of hiPSCs into glial, neural, and blood-brain barrier … Read more

ABSTRACT Kloosterman and colleagues studied molecular and cellular changes during radiation therapy and disease recurrence across molecular subtypes of glioblastoma. They uncovered a distinct immune-cancer cell metabolic crosstalk during proneural/oligodendrocyte progenitor cell-like to mesenchymal-like transition, wherein macrophages feed on cholesterol-rich myelin debris to provide … Read more

ABSTRACT The astrocyte, a major glial cell type in the central nervous system (CNS), is widely regarded as a functionally diverse mediator of homeostasis. During development and throughout adulthood, astrocytes have essential roles, such as providing neuron metabolic support, modulating synaptic function, and maintaining … Read more

ABSTRACT The recent study by Ryu et al. demonstrates that the SARS-CoV-2 Spike protein binds fibrin(ogen), impacting coagulation and immune responses in mice. In this spotlight article we focus on the described effects on natural killer (NK) cell responses as well as the suggested … Read more

ABSTRACT Extrahepatic, cell-autonomous, and/or intracellularly active complement components are increasingly recognized as key orchestrators of cell physiological processes. A recent study by Scott-Hewitt et al. demonstrates that microglia-derived C1q unexpectedly associates with the ribosomes of neurons in the aging murine brain, where it impacts … Read more

Thus, disrupting neuron-cancer crosstalk holds promise for blocking metastasis. Recently, Padmanaban et al. reported new therapeutic targets and showed that breast cancer cells activate sensory neurons to secrete the neuropeptide substance P (SP), leading … Read more
